Team shooting is very different than individual competition. Typically a team coach makes the wind calls for the shooters. In some cases (where the rules allow), the wind coach even dials elevation and windage changes for the active shooter. For the wind coach to do his job effectively, he must follow the changes in the wind and determine what the correct wind call should have been for each shot. (In other words — what was the “right call”)
Bryan Litz, founder of Applied Ballistics and Past USA F-TR National Champion, served as wind coach for the winning 4-man F-TR Team at the 2017 Canadian F-Class Championships, which preceded the F-Class World Championships also held in Canada. Here Bryan explains how he has used a Wind Plot to make better wind calls, helping his team-mates maximize their scores.
Wind Plot Methodology by Bryan Litz
The wind plot I use is a running history of what the correct wind call was for every shot fired. The more you shoot, the more history you have in a condition, and I find that very useful information. This kind of plot IS NOT showing where the bullet hit, and is NOT showing what you held. It’s showing what you should have held to center each shot. IMO, this is the most valuable information to have when guessing where to hold next for each shot. Here are some key points:
1. I always look for blocks of stable conditions to shoot in and wait out the rest.
2. If the wind plot shows drastic changes, either I’m not picking the right time to shoot or it’s just a really unstable wind condition.
3. When you see many shots using the same hold (e.g. Robby’s 700m and 900m strings on plot), it can indicate very fast shooting and fast pit service.
Q. What are the numbers and Markings on this Wind Plot?
Litz: The wind plot represents the rings on the target. Left 2 for example, is the 5 line on the international target, while Left 2 is the 10 line on the USA target. F-Class shooters and coaches talk about wind holds in relation to these rings. A Left 2 hold isn’t left 2 MOA or 2 MILS, it’s the second ring from center. The vertical lines on the plot represent the rings going out from center, 4 or 5 in each direction. A left or right 5 hold is edge of black on the int’l target.
Q: What Does this Specific Plot Reveal?
Litz: Looking at the plot, from left to right is 700m, 800m, and 900m that we shot progressively through the day. Top to bottom shows each shooter in sequence (shooters names are shown by their blocks). To the right I note what was on the gun for that shooter, and note when it changes. Often times we run the same wind on the gun for several shooters but if it changes, I note what the new windage is and continue on. For example if we’re settled into a condition where we’re shooting Vs with a right 3 hold, I might adjust the scope 1 MOA right because a right 3 hold is equal to 1 MOA. So we can move the scope and start shooting with a center hold.
Q. Are you Plotting Where the Bullet Hits?
Litz: Not exactly. This kind of plot IS NOT specifically showing where the bullet hit, and IS NOT showing what the shooter held. It’s showing what the shooter should have held to center each shot. IMO, this is the most valuable information to have when guessing where to hold next for each shot.
On each shot, the shooter or coach takes a guess about where to hold, and fires the shot. If the bullet hits the center, you plot the point right where you held because it was the correct hold. However, if you miss the call, you plot what hold was required to put that shot in the center. For example if you shoot a right 3 and hit where you held, the correct call would have been “center”. In this way, you’re building a history of what you should have done, which may or may not be what you actually did. This shows you the trends, and brackets which can be used to make future decisions.
Q: Is this Type of Wind Plot Something New?
Litz: I didn’t invent this method, it’s been around a long time. Vertical can be plotted the same way. In team matches, we have a plotter who is advising on elevation trends and suggesting corrections. But, as wind coach, my job is the horizontal so I only keep the wind plot. I have learned lots of strategies from my coaches Emil Praslick and Steve Hardin.
There are many ways to plot and many standard work sheets for this. They’re all tools and the key is to find something that works for you in different situations. I don’t keep a plot when I am personally behind the trigger string firing because I lose more points when I take the time to do it vs. just shooting fast. When pair firing or coaching, I can keep the wind plot without compromising the shooting.
Here Team Australia used plots and communication gear linking coaches. This helped the Aussies win the 2013 F-Open Team World Championship held at Raton, NM.
Know Your Goal — Keep It Simple
Know your goal of plotting. The simplest plot is where you write the shot number where it hit on a target face. This kind of plotting is useful for evaluating shooter performance because it shows how big the group is (in particular the vertical dispersion). However keeping a plot like this does little to help you figure out the wind. It just shows you what shots you messed up on. It does nothing to help you find the center. [Editor: That’s a whole different matter with many variables.] The wind plot I use is a running history of what the correct wind call was for every shot fired. The more you shoot, the more history you have in a condition, and I find that very useful information.

While a 16.5-pound benchrest gun is wonderfully stable on the bench, it’s not what you want in a field rifle. There is much to be said for a slim, light-weight, and easy-handling firearm when it comes to a walking varmint adventure. Eben Brown, who runs E. Arthur Brown Company, has created just such a rifle — the Model 97D Falling Block. When chambered for the 6PPC cartridge it delivered quarter-MOA accuracy in a splendidly portable package that tips the scales at just over six pounds without scope. The Model 97D is fairly unique in its lightweight and compact format — that makes it a great field-carry varmint rig. [Editor’s Note: This is an older article and we use some more recent photos of other model 97D Rifles to better illustrate the design and layout.]

Excellent Accuracy Made Easy for Sport Shooters
by Eben Brown, E. Arthur Brown Company
You don’t have to be a benchrest competitor to enjoy shooting one of the most accurate centerfire cartridges in the world, the 6mm PPC. With no complicated brass forming or finicky reloading processes, you can be shooting near half-inch groups right from the start and hone your skills to near quarter-inch groups by your second outing–at least that’s how it worked for me, and I’m NOT a good bench rest shooter! Developed by Louis Palmisano and Ferris Pindell, the 6PPC has won more bench rest accuracy competitions than any other cartridge. Easily made from Lapua .220 Russian brass, the 6mm PPC has a small primer and uniquely small flash hole that is credited for much of its inherent accuracy. The “short, fat” shape and nearly straight body contribute to efficient, consistent powder burning and stable chamber performance (it grips the chamber well during ignition).
The Brown Model 97D — A Slim, Accurate 6-Pound Rifle
The 97D was developed from the EABCO “BF” falling block silhouette pistols that have won world championships and set 500-meter distance records. In operation, the 97D falling block slides perpendicularly and closes the breech with absolutely zero camming leverage. This makes it a perfect test-bed to measure the chamber performance needed for hand-loading most other single-shot rifles accurately. At the reloading bench, I worked up a load with the now fully shaped 6mm PPC brass. I full-length sized the brass, trimmed, and primed each case the same as I would with any other cartridge, and began loading. With the resultant load, I easily shot a 5-shot 1/4″ group, a personal best for me. See target photo at right.
Making 6mm PPC Cartridges
Full-length size, prime, charge with powder, and seat a bullet… sounds like what you do with any other cartridge, doesn’t it? In fact, the only difference with 6mm PPC is that it has to be fired once (fire-formed) to expand to its final shape and size. But even fire-forming shots produce exceptional accuracy. I shot several 3/4″ groups while fire-forming at 100 yards, with my best group at nearly half-inch–so the time spent fire-forming was wonderful! In the photo, the parent .220 Russian case is on the left, while the fire-formed 6PPC case is on the right.
The EABCO 6mm PPC Chamber – 6PPC without Neck-turning!
We dimensioned our 6mm PPC chamber reamer to cut a chamber that fits Lapua 220 Russian brass closely without neck-turning. Naturally we recommend you use the Lapua brass for best results.
[Editor’s Note: We asked Eben if he had tried a 6BR chambering in a model 97D. He explained that, because of the extractor design, the falling block action works better with a smaller rim diameter: “The larger .308 rim width creates some issues. This design works best with cartridges no wider than the 30/30 case, or the 7.62×39 case, from which the 22 Russian case was derived. Cases with .308-sized rims develop more bolt thrust and work best with a different type of extractor than we use in the 97D. I love the 6BR, but I recommend the 6PPC for our 97D.”]
6mm PPC Reloading Data for Model 97D
The following loads were worked up in a Model 97D Rifle with 24″ barrel chambered for 6mm PPC with the chamber neck reamed to .275″ to fit Lapua brass without neck-turning. Lapua 220 Russian brass was full-length sized and fire-formed to 6mm PPC using 65gr V-Max bullets, CCI BR4 primers, and 24.5gr of VV N135 powder. Eben cautions: Load at Your Own Risk — Always start 10% low and work up
The following optimum loads were worked up with Vihtavuori N135, 58gr and 65gr V-Max bullets, and CCI BR4 primers. Please Note: There really is no “standard” for 6mm PPC. It can be finicky. But once you find what works best for you, the cartridge performs superbly. The accuracy will astound you.

This video shows the Loading Technique for Model 97D Rifle
Powder Selection — Choosing the Right Propellant
I’ve found that my maximum single-shot loads reach the same level of performance as bolt gun loads when I use one level slower burning powder type and proper chamber preparation. For example, when the VihtaVuori loading guide shows a maximum with VV N133, my best single shot load ends up being with the slower burning VV N135. Here’s the simplest way to proceed: Use a starting load from the loading guide and increase the powder charge until you detect some resistance to block movement with your thumb. Next, charge a case with that same amount of powder, tap it to settle, and look to see if the case is full to the base of the neck. If it’s not full, step up to the next slower-rated powder and repeat the load development process. There’s a powder burn rate chart for all brands of powder in the front of the current VihtaVuori Loading Guide. When you have the maximum load that will fill the case and still allow the 97D single-shot to open and eject freely after firing, you’re ready to shoot some groups!
Loading for Best Chamber Performance
In the model 97D rifle you can check chamber performance easily. After firing a shot, see if you can press the block downward with only your thumb on the top of the block. If it moves freely, you’ve got good chamber performance.
I use three pressure indicators when developing loads on the Model 97D. First I check the block with my thumb. Then I check to see if the cartridge sticks at all when ejecting. And finally, I check the primer for the excessive flattening that would indicate too much pressure. Generally, the hottest load that still allows the gun to open and eject freely ends up being my most accurate shooting load.
Chamber Preparation
Best chamber performance happens when a cartridge grips the chamber and does not drive backward significantly. When you want something to grip (rather than slip), you want to make sure there is no lubricant on the gripping surfaces. Case forming lube and gun oil are the two lubricants you want to remove. Clean your 6mm PPC cases after sizing (I wipe mine with a paper towel and Windex). Clean your chamber with a chamber sized jag and patch wetted with acetone. (Note: protect your chamber with a thin coat of Clenzoil when you’re not out shooting.)
Conclusions of a Single-Shot Sport Shooter
I love the 6mm PPC! It was easy to hand-load for the cartridge and it was easy to get excellent results. The group shot on this page was with the 65gr bullet and a rifling twist of 1:10. I usually recommend a 1:12 twist and the 58gr bullet because customers have reported superb accuracy (better groups than I can shoot). But the 5-shot ¼” group I shot with this set-up is my personal best ever–so naturally I’m thrilled!
While it’s hard to beat the 6PPC’s accuracy in a Model 97D rifle, my company currently offers the rifle in a variety of chamberings including 17 Hornet, 219 Donaldson Wasp, and 6mm BRM. The 97D Standard features a blued 24″ chrome-moly barrel, French Gray receiver, anodized buttstock transition, 2-ring scope mount and swivel studs.– Eben Brown
About the production Model 97D Rifles: “The 97D is a small frame single shot rifle that’s suitable for big game as well as small game and varmint hunting. It originally evolved from our World Champion long range silhouette pistol action and incorporates the same accurate gun making processes. The 97D action itself is inherently accurate and simple. Onto this we fit an EABCO Accuracy Barrel, precision turned and threaded between centers. Each chamber is individually reamed on-center and individually head spaced. We feel the crown is so critical to accuracy that we leave it until after the gun is finished. Our 11 degree target crowns are cut last and left bright — our trademark finishing touch.”
GunsAmerica Digest has a new Suppressor Academy webpage that provides host of helpful information about suppressors (aka “silencers” and “cans”). The Suppressor Academy online resource page features in-depth articles with important information for anyone considering acquiring a suppressor. The articles explain the key benefits of suppressors, how to choose a suppressor, and how to comply with Federal and state laws regulating suppressors. Below we link to four Suppressor Academy articles. Click the title for each topic to read the full-length article.
Suppressors are now legal in 42 U.S. States. There are certain legal requirements for obtaining a suppressor, including paying a $200 Tax Stamp. To own a suppressor you must be legally eligible to purchase a firearm, pass a BATFE background check, pay a one time $200 Transfer Tax, and satisfy age requirements. (SEE ALL Requirements). In most (but not all) of those states you can use a suppressor for hunting. The eight (mostly blue) states which still prohibit civilian suppressor ownership are: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island. READ FULL ARTICLE on GunsAmerica Digest.
Suppressors serve one main purposes — to reduce the sound levels produced when firing pistol or rifle rounds. But GunsAmerica Digest editor True Pearce notes there are many other reasons to own a suppressor. A suppressor can reduce muzzle blast and felt recoil. The suppressor may prevent hearing damage that occurs through bone conduction better than earplugs and muffs because it reduces the noise energy at the source. When hunting, the reduced shot noise can help avoid spooking game. Having a suppressor also makes it easier to communicate when working as a team on a hunt. And, when compared to a muzzle BRAKE, suppressors are much less likely to kick up dust, dirt, sand, and snow when you shoot prone. READ FULL ARTICLE on GunsAmerica Digest.
There is some confusion surrounding the laws concerning suppressors, which are now legal in 42 U.S. States. In most jurisdictions that allow suppressor ownership, no additional state permit or license is required. But you do have to comply with Federal requirements when acquiring the suppressor. You may wish to create a trust to own the suppressor — there are some important practical advantages to having a suppressor trust. The Traditional NFA Gun Trust allows multiple responsible parties, i.e. “trustees”, to legally have possession of the suppressor. Each trustee must be verified and for each suppressor owned by the trust there will be a $200 Tax Stamp. READ FULL ARTICLE on GunsAmerica Digest.
When shopping for a suppressor there are many factors to consider: price, build quality, materials, sound level reduction effectiveness, weight, ease of mounting, and ease of cleaning and maintenance. We recommend that all suppressor buyers research the options. Check the manufacturer’s reputation, check diagrams for disassembly and maintenance. There are always trade-offs. Shorter suppressors may save some weight, but if they don’t cut the decibels as well you may be disappointed. You also need to consider the caliber — will your suppressor be used on multiple firearms? If so then get one that fits the largest caliber you will shoot. READ FULL ARTICLE on GunsAmerica Digest.
Jessie Harrison — one of the greatest female pistol shooters on the planet. In the video below, Jessie offers good tips on safe handgun mag changes.
In this Pro Tip Video, Jessie Harrison talks about Dry-Fire Pistol Training:
One of our Forum members asked: “Are there any good books on pistol marksmanship? I’m looking for a book that covers techniques and concepts….” Here are eight recommended titles that can make you a better pistol shooter. These books run the gamut from basic handgun training to CCW to Olympic-level bullseye shooting.
Good Guidebooks for Pistol Shooters
There are actually many good books which can help both novice and experienced pistol shooters improve their skills and accuracy. For new pistol shooters, we recommend the NRA Guide to the Basics of Pistol Shooting. This full-color publication is the designated student “textbook” for the NRA Basic Pistol Shooting Course.
If you’re interested in bullseye shooting, you should get the USAMU’s The Advanced Pistol Marksmanship Manual. This USAMU pistol marksmanship guide has been a trusted resource since the 1960s. Action Shooters should read Practical Shooting: Beyond Fundamentals by Brian Enos, and Practical Pistol by Ben Stoeger. Brian Enos is a well-known pistol competitor with many titles. Ben Stoeger is a two-time U.S. Practical Pistol shooting champion. Julie Golob’s popular SHOOT book covers pistol marksmanship, along with 3-Gun competition. Julie holds multiple national pistol shooting titles.

The United States Postal Service allows shipment of long-barreled rifles and shotguns via the U.S. Mail. However, regular citizens who do not possess an FFL are NOT allowed to mail handguns at all.* You must use UPS for handguns (or ship via an FFL). While the USPS allows rifle and shotgun mailing there ARE many rules and regulations with which long gun shippers must comply. Here are key USPS Gun Shipping Rules from the official USPS website. CLICK HERE to Read All Gun Shipping Rules.
U.S. Postal Service Rifle and Shotgun Shipping Rules
432.1 General
Mailers must comply with the Gun Control Act of 1968, all of the provisions of postal law in 18 U.S.C. 1715, and all other all federal and state regulations and local ordinances affecting the movement of firearms. The following also applies:
a. The Postal Service may require the mailer to open parcels containing firearms or air guns or give written certification that the weapon is unloaded and not concealable (see note 1).
b. Short-barreled rifles or shotguns that can be concealed on the person are nonmailable.
c. No markings of any kind that indicate the nature of the contents may be placed on the outside wrapper or container of any mailpiece containing firearms.
d. Mailable matter must be properly and securely packaged within the general packaging requirements in DMM 601.1-7.
e. Except for shipments between licensed dealers, manufacturers, or importers, all regulated firearms must be mailed using a USPS product or Extra Service that provides tracking and signature capture at delivery (see note 2).
432.3 Rifles and Shotguns
Except under 431.2, unloaded rifles and shotguns are mailable. Mailers must comply with the rules and regulations under 27 CFR, Part 478, as well as state and local laws. The mailer may be required by the USPS to establish, by opening the parcel or by written certification, that the rifle or shotgun is unloaded and not ineligible for mailing (see note 1). The following conditions also apply:
a. Subject to state, territory, or district regulations, rifles and shotguns may be mailed without restriction when intended for delivery within the same state of mailing. These items must:
1. Bear a “Return Service Requested” endorsement.
2.Be mailed using a class of mail, product, or Extra Service that provides tracking and signature capture at delivery.
b. A rifle or shotgun owned by a non-FFL may be mailed outside the owner’s state of residence by the owner to himself or herself, in care of another person in the other state where he or she intends to hunt or engage in any other lawful activity. These mailpieces must:
1. Be addressed to the owner.
2. Include the “in the care of” endorsement immediately preceding the name of the applicable temporary custodian.
3. Be opened by the rifle or shotgun owner only.
4. Be mailed using a class of mail, product, or Extra Service that provides tracking and signature capture at delivery.
d. Mailing of rifles and shotguns between licensed FFL dealers, manufacturers, or importers are not restricted. The Postal Service recommends that these items be mailed using a class of mail, product, or Extra Service that provides tracking and signature capture at delivery.
e. Except as described in 432.3a, licensed curio and relic collectors may mail firearms meeting the definition of curios or relics under 27 CFR 478.11 domestically to licensed FFL curio and relic collectors in any state. These items must be mailed using a class of mail, product, or Extra Service that provides tracking and signature capture at delivery.

A shipment containing an air gun with a muzzle velocity of 400 or more feet per second (fps) must include an adult signature service under DMM 503.8. Mailers must additionally comply with all applicable state and local regulations.
FOUR TIPS for Safer, More Secure USPS Firearms Shipping
Here are some other helpful suggestions when shipping long guns via USPS:
1. Bring a copy of the destination FFL holder’s license to the Post Office, just in case the staff asks for confirmation.
2. Use a Shipping Mode that Requires Signature on Delivery for confirmation.
3. Ship Priority Mail for faster delivery and BUY INSURANCE to cover complete replacement value of the firearms. Some guns may be damaged, but insurance is needed to cover full gun value with a lost/stolen shipment.
4. Double tape the ends of the box, and put plenty of padding around the muzzle and buttstock INSIDE the box.
* While ordinary (non-FFL) person may never mail handguns, there are some types of handgun mail shipments allowed by manufacturers etc. to Government and U.S. Military recipients:
432.21 Authorized Persons

Handguns may also be mailed between licensed manufacturers of firearms, licensed dealers of firearms, and licensed importers of firearms in customary trade shipments, or for repairing or replacing parts.
This story is based on a recent NRA-ILA article.
Half the USA’s 50 states now recognize a Constitutional right to carry firearms. Constitutional Carry eliminates the need for government permission before a law-abiding individual can exercise their right to bear arms. A citizen can carry without attaining a CCW permit and/or paying special fees. This is a significant milestone, achieved with the recent passage of Constitutional Carry legislation in Georgia. Georgia Governor Kemp is expected to sign Georgia’s new Constitutional Carry act today, making Georgia the 25th U.S. state to recognize such rights. SEE: Fox News Report on Georgia law.
When Gov. Kemp signs the legislation, Georgia will join Alabama, Alaska, Arizona, Arkansas, Idaho, Indiana, Iowa, Kansas, Kentucky, Maine, Mississippi, Missouri, Montana, New Hampshire, North Dakota, Ohio, Oklahoma, South Dakota, Tennessee, Texas, Utah, Vermont, West Virginia, and Wyoming, in allowing law-abiding individuals to carry a concealed handgun without a government-issued permit.
Before Georgia adopted Constitutional Carry, Ohio passed similar legislation last month, with Ohio Governor Mike DeWine signing S.B. 215, permitting firearms carry by Ohio citizens. READ Ohio Report.
According to the NRA: “The NRA paved the way for Constitutional Carry by first leading the charge for right-to-carry nearly 40 years ago. Today, every state, and the District of Columbia, provides for the carrying of a firearm for self-defense outside the home in some form, and half the nation recognizes the Second Amendment protects law-abiding citizens’ right to self-defense as an inherent and inalienable right.”
The modern carry movement in America began in earnest in 1987 when NRA helped pass a law legalizing concealed carry outside the home for all law-abiding gun owners in Florida. This law established a “shall issue” permitting regime in Florida, meaning the state was required to issue a carry permit to anyone who applied and could legally possess a firearm. Over the next 15 years, NRA successfully worked to establish right-to-carry laws in 42 states.
Constitutional Carry legislation, which eliminates the need for government permission before law-abiding gun owners can carry concealed firearms, was the natural next step after the success of “shall issue” legislation. In 2003, NRA helped to pass constitutional carry legislation in Alaska. Seven years later Arizona joined the fold, followed by Wyoming, Kansas, and Maine. Ten additional states passed similar legislation by 2019. And in the last two years, nine states have become constitutional carry states.
“This is a monumental moment for the Second Amendment, NRA members and gun owners nationwide,” said Jason Ouimet, executive director of NRA’s Institute for Legislative Action. “Half the country now rightfully recognizes the fundamental right to carry a firearm for self-defense as enshrined in our Constitution – as opposed to a government privilege that citizens must ask permission to exercise. Passing this essential legislation has been a priority for the NRA for many years, and we’re thrilled to celebrate this huge success.”
How to Fill Shooting Sandbags Most Effectively
For both front and rear Edgewood bags, start by looking for the black nylon/cordura flap. This flap will have white stiches running along both sides. Note that the flap is actually two pieces of nylon/cordura which are sewn together. These two pieces must be separated at the end where there are no stitches in order to insert a funnel or other filling device.
Hold the bag so that the flap is pointed straight up and fill half way. Using a blunted rod and alternating between filling and packing, begin packing the sand firmly into the bag until the shape is uniform and you are satisfied with the firmness. Slam the base of the bag firmly on the bench several times to compact and evenly seat the sand. Then, check to see if more sand needs to be added. Repeat this process for the ears if you are filling a rear bag. Note that as the sand continues to condense during use, the bag may occasionally require additional sand until it reaches maximum capacity. NOTE: This tip is from Creedmoor Sports, which carries Edgewood Shooting Bags.
Edgewood offers an innovative rear Twisted Gater bag with an unusual asymmetrical footprint. This provides arm/hand support for the shooter while still providing superb rear support for your bench rifles.
SANDBAG Fill Options — Yes Weight Matters
For most shooting applications, “heavy is good” when it comes to sandbags. The more your sandbag weighs, the better it will resist movement or mis-alignment that can throw off a shot. In order to increase the weight of their rear bags, serious shooters have turned to exotic sand formulations that offer greater density (hence higher weight by volume) than plain silica sand (aka “play sand”).
In this article, Jason Baney reviews three popular alternatives to play sand for rear sandbags. He tested each variety to determine its density, i.e. how much volume it would displace per pound. Then he calculated how much each type of sand would weigh in various sizes of rear sandbags: standard, large, and ultra-large (Bigfoot). Check our Rapid Reference Chart to see how much weight you can add to your sandbag by switching to heavy sand.
Is heavy sand worth the added expense? For serious shooters, the answer is yes. More mass equals more stability, and a more stable bag will help you shoot tighter groups. By switching from conventional sand to Zircon or Chromite, you can DOUBLE the weight of sand in your rear bag.
Shown above are the latest SEB Bigfoot Bags. Note that the bags sit perfectly flat — there is no bulge on the bottom even though the bags are “packed to the brim with sand”.
Heavy Sand — Weighing the Benefits by Jason Baney
Many serious Benchrest shooters fill their sand bags with “heavy sand”. This practice may seem “overkill” to most shooters, but its benefits are realized quickly when shooting from a bench. Heavy sand is more dense than normal silica “play sand” and therefore makes the sandbag heavier and more stable. How much heavier is the heaviest sand? Check the chart below and you’ll see that Zircon sand weighs essentially TWICE as much as ordinary play sand. More weight equals more inertia opposing bag movement, plus more gravity-induced “stiction” on the bottom of the bag. In other words, using heavy sand helps your rear bag stay planted on the bench during a string of fire. When you shoot a hard-recoiling gun, the difference between a bag filled with play sand vs. Zircon is very noticeable. The Zircon-filled bag stays put. The play sand-filled bag may not.

The Benefits of Heavier Sand
Heavy Sand helps your sandbag resist the tendency to shift or change alignment (relative to the stock) during recoil. This ability to maintain sandbag alignment is vital when shooting competitive Benchrest, either short-range or long-range. Having to fight a “migrating” rear bag during a group at 1000 yards will not do anything to help your accuracy. In non-competitive use, heavy sand can still benefit shooters. Friction from the stock on the rear bag, or bumping the bag on recoil with either a body part or pistol grip can move a lighter bag out of place and necessitate realigning the bag to get on target.
Of course there are some shooting situations where you don’t need (or don’t want) maximum sandbag weight. During a “walk-around” varmint session you may prefer a lighter bag. Beanbags that I carry around the groundhog fields stay filled with plastic beads, making the bag handier to tote. But, any rear bag used on a bench will be as heavy as I can make it while still using “sand” as filler.
Heavy Sand, Lead Shot, and Competition Rules
Some will say, “Well if you want a heavier sandbag, why not just add lead shot?” That is a great idea, but as far as I know, it is also illegal in every form of Benchrest competition. The material in sandbags must actually be “sand”, and only sand. It’s tempting to filter in a mix of shot and sand to increase weight, but that would also violate the rules.
Heavy Sand — Available Types and Properties
Heavy sand comes in several different varieties. In this article we tested three types: Zircon, Chromite, and commercial Riverbed sand (Exo-Terra brand “Reptile Sand”). All these are heavier alternatives to normal silica “play sand.” There are other types of Heavy Sand not tested here, such as Garnet Sand, which is between Chromite and Zircon in weight.
Sources: Sinclair Int’l sells black “Heavy Sand”, basically chromite. Large quantities of Zircon and Chromite are available from IFS Industries, and other industrial suppliers.
Exo-Terra Riverbed sand (amber). Available at pet stores.
Silica “Play Sand” (tan or light gray). Available at Home/Garden stores.
Zircon — Heavy-Weight Champion
To my knowledge, “Dupont Zircon M” is the heaviest “sand” that a normal human can acquire. It is also the most expensive. Zircon is a very light tan/brown color and is very similar in appearance to normal sandbox “play sand”. Zircon is normally rated as having the greatest density among heavy sands and it has the smallest particle size, though some Chromite sand density values overlap the Zircon numbers.
1.00 pound of Zircon displaces 149cc vs. 295cc for Play Sand. So, that means Zircon is 98% heavier than an equal volume of Play Sand.
CONSUMER TIP: Real ZIRCON sand is TAN in color, not black or dark gray. Some “heavy sand” vendors promise Zircon but deliver a dark gray sand that is something else entirely!
Chromite — Almost as Heavy as Zircon, and 30% Cheaper
Chromite sand is nearly the same density as Zircon but it costs quite a bit less. Chromite typically sells for about 25-30% less than Zircon (comparing bulk prices of both types of sand). Chromite sand is black in color. So when you buy “heavy sand,” make sure you are getting what you pay for.
1.00 pound of Chromite displaces 152cc vs. 295cc for Play Sand. So, that means Chromite is 94% heavier than an equal volume of Play Sand.
Riverbed Sand — Weighs Less but Costs More than Chromite
Riverbed sand, is about 30% less dense than Zircon or Chromite, but is about 150% more dense than silica sand. Depending upon where you buy this sand, and the quantity, you will most likely pay more for this sand than you would Zircon or Chromite. Riverbed sand is a conglomerate of several different sizes and colors and appears red and black. Unless you are unable to get Zircon or Chromite, I would not bother with the riverbed sand.
1.00 pound of Riverbed Sand displaces 190cc vs. 295cc for Play Sand. So, that means Riverbed Sand is 55% heavier than an equal volume of Play Sand.
Density/Volume Testing and Weight Comparisons
All four sand varieties mentioned above were tested for volumetric density by weight. Each type of sand was weighed out to 1.00 lbs. on a commercial postal scale. Each 1.00 lb sample of sand was then poured loosely into a 600ml beaker and shaken minimally to level the top surface. This served to determine the volume that the sand occupied.
1.00 pound of sand displaced the following volumes:
Zircon: 149 cc
Chromite: 152 cc
Riverbed sand: 190 cc
Play Sand: 295 cc
How do the density-volume numbers translate to the real world? Here is an estimate of how much each sand would weigh in various sizes of rear bag:
Standard Bunny Ear Bag
5″ by 6″ footprint or about 1500cc
Zircon: 10.1 lbs.
Chromite: 9.9 lbs.
Riverbed Sand: 7.9 lbs.
Play Sand: 5.1 lbs.
Protektor Doctor Bag
6″ by 8″ footprint or about 2000cc
Zircon: 13.4 lbs.
Chromite: 13.2 lbs.
Riverbed Sand: 10.5 lbs.
Play Sand: 6.8 lbs.
Seb BigFoot Rear Loaf Bag
6″ by 13″ footprint or about 3000cc
Zircon: 20.1 lbs.
Chromite: 19.7 lbs.
Riverbed Sand: 15.8 lbs.
Play Sand: 10.2 lbs.
Conclusions and Recommendations
What’s the best choice? For most users, we recommend Chromite. Chromite delivers nearly the same bag weight as Zircon but is more economical to buy. But for those who demand the maximum weight in their sandbag (without consideration of cost), Zircon is the top choice because it is sold at a finer grade (higher density) than Chromite. However, Chromite will save you money, and deliver very nearly the same amount of weight by volume. When purchased in bulk, Chromite is typically 25-30% LESS expensive than Zircon.
I would not suggest using the Riverbed sand unless you really need to fill a sandbag immediately and can’t wait to locate a source for either Zircon or Chromite. Keep in mind that Sinclair Int’l and other major mail-order vendors do sell heavy sand (though Zircon and Chromite may be much less expensive when purchased in larger quantities from local industrial sources.) The price of the Riverbed sand will vary quite a bit depending on the pet store and quantity bought. The Riverbed sand I tested, Exo-Terra Reptile sand (photo right), was fairly expensive as purchased at a pet store.
Bottom Line: When it comes time to fill your new rear bag, you may want to save a few dollars and go with cheaper Chromite sand, but if you want to gain every bit of weight possible, step up to the heavier Zircon.

At the request of our Shooters’s Forum members, we’re repeating an excellent article by Steven Blair on wind reading. Steven, a top F-Class shooter, talks about mirage, topography effects, tail winds, and other subtle factors that can cause frustration for shooters. Steve explains that wind effects can be complex — there’s more going on than just velocity and angle. You need to notice things like berm locations and effects of temp changes over the course of the day.
Wind Reading Tips for Competitive Shooters by Steven Blair, Past California State Long Range F-Open Champion
Assess the Terrain and How the Wind Will Interact with It
Before you begin a match, take a few minutes to look around the range at the terrain, any obstructions, range topography (berms and backstop), and trees, buildings or structures that could affect wind flow over the range. Imagine what might happen if the wind was from the left or right, headwind or tailwind. Depending upon the direction, significant effects may be seen on range. A head or tail wind may ripple across the berms, causing elevation changes, both high and low. A tall side berm, like the east side berm at Ben Avery, may cause turbulence when the wind comes from that direction. Blocking features might shield most of the wind but a break along the range can funnel strong gusts through the gap with no other indications. Take a few notes about the effects of different wind directions and refer to them if the prevailing direction changes. (Tip courtesy Tony Robertson.)
Use a Spotting Scope, Even When Shooting a Scoped Rifle
A good spotting scope can “see” mirage much more clearly than even an expensive rifle scope. Take your spotting scope to the line and position it as sling shooters do, close enough to use without much movement. Focus the scope approximately 1/3 of the way down range or where the most significant wind effects are likely to occur. Take a quick look while waiting for pit service, glance at the flags and compare to your scope sight picture. I often see ambiguous indications at the target through the rifle scope, but see a clear indication of wind direction and speed through the spotting scope at the shorter distance. When shooting the Arizona Palma Championship at Ben Avery last weekend, I was scoring while the wind was coming from the east. Shooters up and down the line were out to the left, losing points. Mirage at the target looked moderate and the flags weren’t indicating strong wind. As I focused the spotting scope back, the mirage suddenly looked like it was flowing twice as fast around 500 yards than it was closer or farther. It wasn’t until I realized that the access road cut through the berm there that I understood what was happening. (Tip courtesy Gary Eliseo.)
Don’t Over-React to Something That May Be an Anomaly
On ranges with sizable berms, a headwind or tailwind can cause significant elevation problems. It is generally not possible to see or predict when this will occur. When the conditions exist that cause elevation changes and other competitors are experiencing the same problem, the best strategy is to ignore it. Certainly, avoid shooting when the head or tail wind is gusting, the same as you would in a crosswind. But, if you react to random, range-induced elevation changes, the only likely result is to make it worse. Whether the problem is caused by range or ammunition, maintain your waterline hold until you have evidence that something has fundamentally changed.
My .284 Shehane will usually require a click or two down during a string as the barrel warms. That is normal and manageable. But, if your shots are just bouncing up and down in the 10 ring, leave it alone. The same is also true of an occasional gust pushing a shot into the 9 ring. If the conditions have not changed and one shot just went out, it may be the result of a random occurrence that was not predictable. (Tip courtesy “School of Hard Knocks”.)
Adjust Spotting Scope Focus and Magnification as Needed to View Mirage vs. Target Details
In F-Class we only need to see mirage, spotters, and scoring disks. That does not take a lot of magnification. My scope is a Nikon 25-75x82mm ED. It is a superb scope for the money and makes it trivial to see minor variations in mirage. It is good to have the high magnification available, and it can always be reduced if necessary. I use different power settings for different situations.
Setting Magnification Levels
During a match, in very good viewing conditions, I set my spotting scope at 75X, full power. The mirage is more subtle in the morning and greater magnification is needed.
During a match with heavy mirage I set my spotting scope at about 40X. I have no problem seeing mirage, even at this magnification.
When practicing at 300 yards or closer I set my spotting scope at max power (75X) so I can see the little 6mm holes from my 6BR rifle. I usually need to focus back and forth between shots to see both bullet holes and mirage.

Are sound suppressors useful in competition shooting? In some disciplines, and in venues where sound “moderators” are permitted, the answer is “yes”. In the November edition of Shooting Sports USA eZine, you’ll find an interesting article about the use of sound suppressors (aka “cans”). The article explores the use of suppressors in Europe and in tactical matches in North America. You’ll also find an explanation of the rules and regulations governing suppressor ownership and use in the United States.
Shooting Sports Editor Chip Lohman tests three rifles from the bench and found that sound suppressors did not harm accuracy. In fact, all three test rifles (one each in .223 Rem, .308 Win, and .338 Lapua Magnum), shot slightly better 5-shot groups at 200 yards when a suppressor was fitted to the barrel. However, the suppressors did alter point of impact. Interestingly, velocity standard deviation (SD) values were lower with suppressors in place for all three test rifles. This observation calls for further study.*
So the use of suppressors in competition could be a good thing. However, in the United States, current NRA rules prohibit the use of sound suppressors. NRA Rule 3.16.1 subsection (a) states: “Sound Suppressors are not authorized for use in High Power competition.” In addition, there are some practical problems with suppressors — the heat rising off of a naked suppressor can create mirage problems (that’s why some shooters wrap their cans with a cover).
Despite such issues, now commonly see suppressors on rifles used in tactical matches and PRS/NRL events. For example, many competitors in the Steel Safari field challenge match use suppressors. The photo below shows our friend Zak Smith competing in the Steel Safari with his suppressed Accuracy International rifle.
Commentary — What Can We Conclude?
Obviously, this three-rifle SSUSA test was not definitive. One well might observe different results with different types of suppressors, fitted to different kinds of rifles. Mounting a suppressor to any barrel will certainly affect harmonics and “tune”. But this SSUSA study does suggest that tactical shooters, who are allowed to use suppressors in competition, may find that the benefits of suppressors (significantly reduced recoil and less noise) outweigh any meaningful accuracy loss, at least in PRS-type matches.
NOTE: The article cautions that one should not extrapolate too much from the SD numbers, given the low number of test shots. Chronograph-maker Ken Oehler, when asked to comment on the SD values stated: “[You should] report the observed SDs, but draw no conclusions until… you can do more testing with larger sample sizes.”
Qualifications to Obtain a Suppressor
To legally obtain a suppressor, you must fill out Federal Forms and pay a $200 fee to the ATF. You must also pass BATFE background checks and otherwise comply with Federal and state laws. States can regulate suppressor ownership or use, so be sure to check the laws in your area. On the federal level, the process to acquire a suppressor is regulated under the National Firearms Act of 1934.

How to Fill Shooting Sandbags Most Effectively
For most shooting applications, “heavy is good” when it comes to sandbags. The more your sandbag weighs, the better it will resist movement or mis-alignment that can throw off a shot. In order to increase the weight of their rear bags, serious shooters have turned to exotic sand formulations that offer greater density (hence higher weight by volume) than plain silica sand (aka “play sand”).
Many serious Benchrest shooters fill their sand bags with “heavy sand”. This practice may seem “overkill” to most shooters, but its benefits are realized quickly when shooting from a bench. Heavy sand is more dense than normal silica “play sand” and therefore makes the sandbag heavier and more stable. How much heavier is the heaviest sand? Check the chart below and you’ll see that Zircon sand weighs essentially TWICE as much as ordinary play sand. More weight equals more inertia opposing bag movement, plus more gravity-induced “stiction” on the bottom of the bag. In other words, using heavy sand helps your rear bag stay planted on the bench during a string of fire. When you shoot a hard-recoiling gun, the difference between a bag filled with play sand vs. Zircon is very noticeable. The Zircon-filled bag stays put. The play sand-filled bag may not.
