Readers often ask for a good, authoritative resource on doping the wind and reading mirage. Many of our Forum members recommended M.Sgt. Jim Owens’ Wind-Reading Book. With 22 sets of wind charts, this 166-page resource is offered for $14.95 in print format or $12.95 in CD format.
Owens’ Reading the Wind and Coaching Techniques clearly explains how to gauge wind speeds and angles. Owens, a well-known High Power coach and creator of Jarheadtop.com, offers a simple system for ascertaining wind value based on speed and angle. The CD also explains how to read mirage — a vital skill for long-range shooters. In many situations, reading the mirage may be just as important as watching the wind flags. Owens’ $12.95 CD provides wind-reading strategies that can be applied by coaches as well as individual shooters.
NOTE: The Wind DVD product is completely different than Owens’ $12.95 CD. The DVD is like an interactive class, while the CD is basically an eBook.
Played straight through, the DVD offers about 75 minutes of instruction. M.Sgt. Owens says “You will learn more in an hour and fifteen minutes than the host learned in fifteen years in the Marine Corps shooting program. This is a wind class you can attend again and again. [It provides] a simple system for judging the speed, direction and value of the wind.” The DVD also covers mirage reading, wind strategies, bullet BC and more.
The 2020 Berger Southwest Nationals, one of the biggest (and best) rifle competitions of the year, kicks off Wednesday, February 5, 2019 at the Ben Avery Range outside Phoenix, Arizona. The big match continues through Sunday, February 9th. This match attracts the top F-Class and sling shooters in the country, along with many talented foreign competitors.

Didn’t get enough gun stuff in Sin City during SHOT Show? Then head to Reno, Nevada for the biggest hunting/safari show of the year. The 48th Annual Safari Club International (SCI) Hunters’ Convention kicks off today, Wednesday, February 5, 2018, at the Reno Sparks Convention Center. The big event runs through Saturday, February 8, 2018. Over 20,000 hunters and sportsmen are expected to attend this year. Ask any member who has attended the SCI Convention, and you will likely hear, “You have to go! It is the ultimate hunters’ market/showcase.”
This year’s convention will have almost 1,100 companies in over 450,000 square feet of exhibit space. Thirty-two countries from six continents are represented under one roof where members come to book hunts, meet outfitters, and shop for guns, hunting equipment, and outdoor gear. There will be dozens of seminars covering hunting techniques, care for gear/equipment, and ways to prepare wild game.
Impressive Selection of Auction Items This Year
The SCI show is famed for its gun, safari, and outdoor art auctions which raise money for the organization. At this year’s Convention, exotic firearms, once-in-a-lifetime hunts, and fine collectibles will be auctioned. Net proceeds from the auctions are used by SCI to promote conservation and game management efforts worldwide. CLICK HERE for Auction Preview Guide.
Here are some of the hunts which will be auctioned:
And here is one of the most impressive firearms to be auctioned at the 2020 show, a classic “Big Five” Double Rifle from Krieghoff International, valued at $18,690.
The SCI convention boasts “the largest display of wildlife art at one venue anywhere in the world” according to Ammoland.com. The work of scores of painters, sculptors, and taxidermists will be on display. There will be auctions of wall paintings and sculpture items, such as this Bronze Buck:
Guided Hunts in Exotic Destinations
At the SCI Convention, hundreds of top guides and outfitter services are showcased in the Outfitters Hall. You will find hunting guides who can literally take you to the ends of the earth to find prize game. From the Arctic to Africa to New Zealand’s Southern Alps, you will find “dream hunts” to pursue.
Are you a confirmed wildcatter? Do you like to experiment with custom cartridge types? Or do you just like the extra performance you can get from a specialty cartridge such as a 20 Vartarg or 22-250 AI? Well, if you love wildcat cartridges, you’ll probably enjoy this book. Now available for the first time since 2003, The Handloader’s Manual of Cartridge Conversions explains the processes and tools needed to convert standardized brass into hundreds of different rifle and pistol cartridge types. A vast variety of case designs are covered — from vintage cartridge types to modern, cutting-edge wildcats.
This classic reference guide has been revised with an easy-to-search format, complete with a full index of hundreds of cartridges. This book belongs on the shelf of any hand-loader who enjoys making and shooting wildcat cartridges. However do note that much of the text is unchanged from earlier editions. For some cartridge types, the author recommends “parent” brass brands that are no longer available. In other situations, there may be more convenient conversions now offered. Nonetheless this is an important resource. As one verified purchaser explains: “Great reference for making the cartridges that are hard to get or no longer in production. Offers an alternative to the the time, expense and effort of having to re-chamber a classic. Saves ‘Grandpa’s shooters’ from becoming safe queens.”
The 2020 Berger Southwest Nationals kicks off 2/5/2020 at the Ben Avery Range outside Phoenix, AZ. The big event starts with a 600-yard Mid-Range Match. Many of the nation’s most talented F-Class and sling shooters will be there. But no matter what your skill level, it is still possible to make major mistakes that can spoil the day and/or put you out of the running for the entire match. This article aims to help competitors avoid the big errors/oversights/failures, aka “train wrecks”, that can ruin a match.

In any shooting competition, you must try to avoid major screw-ups that can ruin your day (or your match). In this article, past F-TR National Mid-Range and Long Range Champion Bryan Litz talks about “Train Wrecks”, i.e. those big disasters (such as equipment failures) that can ruin a whole match. Bryan illustrates the types of “train wrecks” that commonly befall competitors, and he explains how to avoid these “unmitigated disasters”.
Urban Dictionary “Train Wreck” Definition: “A total @#$&! disaster … the kind that makes you want to shake your head.”
Success in long range competition depends on many things. Those who aspire to be competitive are usually detail-oriented, and focused on all the small things that might give them an edge. Unfortunately it’s common for shooters lose sight of the big picture — missing the forest for the trees, so to speak.
Consistency is one of the universal principles of successful shooting. The tournament champion is the shooter with the highest average performance over several days, often times not winning a single match. While you can win tournaments without an isolated stellar performance, you cannot win tournaments if you have a single train wreck performance. And this is why it’s important for the detail-oriented shooter to keep an eye out for potential “big picture” problems that can derail the train of success!
Train wrecks can be defined differently by shooters of various skill levels and categories. Anything from problems causing a miss, to problems causing a 3/4-MOA shift in wind zero can manifest as a train wreck, depending on the kind of shooting you’re doing.
Below is a list of common Shooting Match Train Wrecks, and suggestions for avoiding them.
1. Cross-Firing. The fastest and most common way to destroy your score (and any hopes of winning a tournament) is to cross-fire. The cure is obviously basic awareness of your target number on each shot, but you can stack the odds in your favor if you’re smart. For sling shooters, establish your Natural Point of Aim (NPA) and monitor that it doesn’t shift during your course of fire. If you’re doing this right, you’ll always come back on your target naturally, without deliberately checking each time. You should be doing this anyway, but avoiding cross-fires is another incentive for monitoring this important fundamental. In F-Class shooting, pay attention to how the rifle recoils, and where the crosshairs settle. If the crosshairs always settle to the right, either make an adjustment to your bipod, hold, or simply make sure to move back each shot. Also consider your scope. Running super high magnification can leave the number board out of the scope’s field view. That can really increase the risk of cross-firing.
2. Equipment Failure. There are a wide variety of equipment failures you may encounter at a match, from loose sight fasteners, to broken bipods, to high-round-count barrels that that suddenly “go south” (just to mention a few possibilities). Mechanical components can and do fail. The best policy is to put some thought into what the critical failure points are, monitor wear of these parts, and have spares ready. This is where an ounce of prevention can prevent a ton of train wreck. On this note, if you like running hot loads, consider whether that extra 20 fps is worth blowing up a bullet (10 points), sticking a bolt (DNF), or worse yet, causing injury to yourself or someone nearby.
3. Scoring/Pit Malfunction. Although not related to your shooting technique, doing things to insure you get at least fair treatment from your scorer and pit puller is a good idea. Try to meet the others on your target so they can associate a face with the shooter for whom they’re pulling. If you learn your scorer is a Democrat, it’s probably best not to tell Obama jokes before you go for record. If your pit puller is elderly, it may be unwise to shoot very rapidly and risk a shot being missed (by the pit worker), or having to call for a mark. Slowing down a second or two between shots might prevent a 5-minute delay and possibly an undeserved miss.

4. Wind Issues. Tricky winds derail many trains. A lot can be written about wind strategies, but here’s a simple tip about how to take the edge off a worse case scenario. You don’t have to start blazing away on the command of “Commence fire”. If the wind is blowing like a bastard when your time starts, just wait! You’re allotted 30 minutes to fire your string in long range slow fire. With average pit service, it might take you 10 minutes if you hustle, less in F-Class. Point being, you have about three times longer than you need. So let everyone else shoot through the storm and look for a window (or windows) of time which are not so adverse. Of course this is a risk, conditions might get worse if you wait. This is where judgment comes in. Just know you have options for managing time and keep an eye on the clock. Saving rounds in a slow fire match is a costly and embarrassing train wreck.
5. Mind Your Physical Health. While traveling for shooting matches, most shooters break their normal patterns of diet, sleep, alcohol consumption, etc. These disruptions to the norm can have detrimental effects on your body and your ability to shoot and even think clearly. If you’re used to an indoor job and eating salads in air-conditioned break rooms and you travel to a week-long rifle match which keeps you on your feet all day in 90-degree heat and high humidity, while eating greasy restaurant food, drinking beer and getting little sleep, then you might as well plan on daily train wrecks. If the match is four hours away, rather than leaving at 3:00 am and drinking five cups of coffee on the morning drive, arrive the night before and get a good night’s sleep.”
Keep focused on the important stuff. You never want to lose sight of the big picture. Keep the important, common sense things in mind as well as the minutia of meplat trimming, weighing powder to the kernel, and cleaning your barrel ’til it’s squeaky clean. Remember, all the little enhancements can’t make up for one big train wreck!
Forum members are lamenting that they can’t find Hodgdon H4350 at local gunstores or through major online Vendors. There ARE a few shops that do have H4350 (and Varget) on the shelves. But the nearest H4350 may be in another state, far away. Therefore, you may want to consider using Alliant Reloder 16 (RL16). We highly recommend Reloder 16 for shooters who can’t find H4350. RL16 has a very similar burn rate, excellent accuracy, and is VERY temp stable. Some ace F-Class shooters (among Top 10 at Nationals) tell us that, with hot ambient temps (80-100+° F), RL16 is even more temp stable than H4350.
Powder Availability at Online Vendors — H4350, Reloder 16, Varget
*This is available in-store only at a few locations. You need to search store locations near you for availability. For example, H4350 8-pounders are available in a couple locations including Show Low, AZ and Midvale, UT. Varget 8-pounders are available in AZ, NM, and WY and a couple other states.
Do You Like H4350? Then You Should Try Reloder 16 — It Is Accurate and Temp Stable
Alliant Reloder 16 is used now by many top shooters for cartridges that work well with Hodgdon H4350. In fact, we’d say that Reloder 16 is the best substitute for H4350 on the market. Alliant’s RL 16 is very temp stable, offers good velocity, and the accuracy is top tier. Some guys report slightly better accuracy than H4350 in the .284 Win, .260 Rem, 6.5 Creedmoor, 6mm Creedmoor, and 6XC cartridges. If you currently use H4350, you should definitely give Alliant Reloder 16 a try. The powder also boasts excellent lot-to-lot consistency and contains a proprietary de-coppering additive.
This is NOT just a slower version of Alliant’s double-based Reloder 15 (which words great in the 6mmBR and Dasher cartridges). Reloder 16 is a completely new formulation, produced in Sweden by Bofors for Alliant. Reloder 16 utilizes TZ technology, which manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures. As a result, Alliant’s Reloder 16 offers truly outstanding temperature stability.

With the Berger Southwest Nationals (SWN) taking place this week in Phoenix, we are reprising this discussing of rear bag designs and fill levels. By “tuning” your rear bag you can reduce hop on shot-firing and help your rifle track better. All that can translate to better scores, particularly with large-caliber rifles.
Tuning Your Rear Sand Bags
Over the years, noted gunsmith and a Benchrest Hall-of-Fame inductee Thomas ‘Speedy’ Gonzalez has learned a few things about “tuning” rear sandbags for best performance. On his Facebook page, Speedy recently discussed how sand bag fill levels (hard vs. soft) can affect accuracy. Speedy says you don’t want to have both your front and rear sandbags filled up ultra-hard. One or the other bag needs to have some “give” to provide a shock-absorbing function (and prevent stock jump). And you want to tune your fill arrangements to match your shooting style. Free recoil shooters may need a different fill levels than bag squeezers (who a softer bag but harder ears).
SAND BAGS & HOW TO FILL THEMby Speedy Gonzalez
I was asked several times by competitors at the S.O.A. Matches and F-Class Nationals as to how I fill my sand bags for benchrest competition. Here is a copy of a reply I gave several years ago:
Back in the old days, Pat McMillan told me: “You can not have two bags filled so hard that you gun bounces on them in the process of firing round at your target, especially if you have a rig with a very flexible stock. The bags must be set up in a manner for them to absorb the initial shock of the firing pin moving forward and igniting the primer.
Then [they must] maintain their shape and absorb the second shock wave as well the rearward thrust and torque of the rifle. What happens to the rifle when this is not done? Well let me tell you. The rifles have a very bad tendency to jump and roll in the bags. This causes many of those wild, lost shots that one can’t explain.”
Here’s some Good General Advice for Bag Set-up:
1. You should not have TWO hard bags [i.e. both front AND rear] in your set-up.
2. Heavy sand magnifies these phenomena.
3. If you are a bag squeezer, pack ears hard and leave bag pliable enough to squeeze for the movement required. You may pack front bag as hard as rules permit.
4. Free recoil shooters pack both bags firm, but not so hard as to allow stock jump. Especially if you have a stock with a very flexible forearm.
5. We use play-ground sand, also know as silica sand. I sift mine to get any large impurities out then mix it with 25% to 50% with Harts parakeet gravel to the desired hardness that I am looking for. The bird gravel keeps the sand from packing itself into that solid as a brick state.
Speaking of bricks — another thing that happens when shooters employ that heavy zircon sand is the ears form a low spot under them from recoil and then tend to rock back and forth with the rifle causing many low shots to crop up. Edgewood makes an Edgewood/Speedy rear bag specially reinforced under the ears to eliminate this scenario.
General Thoughts about Bag Construction and Ear Materials
I do not like the solid double-stitched leather bottoms. While this seems like a good idea, I see more shooters have problems because of them. They tend to slide around the bench and or slide with the rifle on recoil. The standard Protektor with Cordura rabbit ears and an Otto ring bag with a Cordura front would be what I would suggest to the new shooter or one of the Edgewood / Speedy rear bags, these mimic the “Donut” and feature a ring of leather around the bottom circumference that keep the bottom from rocking on the bench or ground[.]
One last note –If you use the Cordura bags, keep them sprayed with a good silicon spray or “Rain-Ex”. This keeps them from getting sticky. — Speedy
With the Berger Southwest Nationals commencing this week, we thought our readers would appreciate a showcase of two impressive, state-of-the-art F-Open match rifles. The first, show above, is the .284 RAHM (40° .284 Win Imp) with which Brian Bowling captured the 2019 F-Class Open Division Long Range National Championship. The second rifle belongs to barrel-maker Bryan Blake. Like Bowling’s rifle, Blake’s rig features a low-profile Cerus stock, but with purple highlights. Both rifles have 6-groove, cut-rifled barrels from Blake Barrel & Rifle and both sport Nightforce scopes.
Twin World-Class F-Open Rifles
Report from Bryan Blake of Blake Barrel & Rifle
We had been producing gun barrels for about 1.5 years prior to the 2019 NRA Long Range F-Class Nationals. Brian Bowling started shooting our 7mm barrels in May of 2019. Bowling and I are both on the Rutland team, Team Cerus, which has seven members. Bowling and I received the first Cerus XL stocks from Cerus Rifleworks in August of 2018. The stock was a very straight design.
With our barrels, these F-Open rigs can shoot! In 2018, Brian Bowling and I had the only two clean scores for the first match at the 1000-yard team NRA Nationals. In spring of 2019, I worked with Will of Cerus Rifleworks to see if we could come up with a lower center of gravity design to enhance what was already the straightest stock out there. We developed the Cerus XR stock which features stepped metal rails on the fore-end. I cut my XL Cerus stock and designed the rail system attached to the sides of the fore-end. Bowling’s stock (with black rails) was the second XR in the shooting world. On his very first weekend match at 600 yards he shot a 200-20X with the new XR stock and Blake 7mm 1:8.5″-twist barrel. He was using Berger 184gr 7mm bullets.
In 2019, at the NRA F-Class Long-Range Nationals, Brian Bowling won the F-Open National Championsship with a strong performance. He finished with a ton of Xs, three points ahead of the second place competitor. Before Brian’s impressive victory, we were told by many top shooters that a 6-groove barrel has never won any F-Class Mational event, and hypothetically never would. Well with Brian Bowling’s excellent shooting and reloading capabilities, we achieved a feat many said couldn’t be done.
Bowling’s Championship-winning rifle features a Bat Model B action in the Cerus XR stock. His Blake barrel is chambered for the .284 RAHM wildcat cartridge. This is a 40-degree (40°) version of the .284 Winchester. The .284 RAHM has a straighter case body compared to the original .284 Win.
We built Bowling’s rifle, doing everything except the final clear finish. We can do that work, but were short on time for the Nationals last year. We are proud of the chambering work we do and the quality of our bedding jobs.
Bryan Blake’s F-Open Rifle — the Purple XR
The Purple XR-stocked gun I shoot was built in August of 2019, right before the 2019 NRA F-Class Nationals. The natural wood is complimented by highlights finished with a bright purple metallic epoxy resin that Will from Cerus dreamed up. For this rifle we mated a BAT 3LL action with Blake barrels (switch-barrel configuration). Up front the fore-end rails are painted purple “plum crazy” to match the purple resin. The purple XR is finished with automotive “high solids” clear-coat, and block-sanded for a smooth, flawless look.
Blake’s Rifle is a Switch Barrel — 7mm and .30 Caliber
This Purple XR was set up to be a switch barrel rig, with both a 7mm BBM and a .30 BBM*. These BBM wildcats are based on shortened and straightened .300 WSM with a 40-degree shoulder. On my purple XR rifle as well as Bowling’s rifle, we employ Nightforce optics and load Berger bullets. These are the only glass and projectiles we use in our rifles.
The Purple XR is extremely accurate. Check out this 2.6″ group, shot at 1000 yards during a club match at the Ben Avery Range in Arizona. Yes, that is 1/4-MOA at 1K! Many folks would be very happy with that group at 600 yards. At 1000 yards it is remarkable. No, the rifle can’t do that every time. But this does demonstrate that the Purple XR is a tack-driver. CLICK HERE to see a 3.9 inch, 15-shot group at 1000 yards on the F-Class target (150-15X).
About Blake Barrel and Rifle — History and Barrel-Making Process
Blake Barrel and Rifle was re-launched in 2018. The business was actually started by my grandfather, Robert Blake, in 1966. In 1969 my grandfather stopped doing gunsmithing and making single-point cut-rifled barrels. He transitioned to doing industrial work, and less work for the public. After all those years he and my father, Dave Blake, kept the barrel-making equipment in storage. They kept the gun-drilling machines in the shop as they used them to drill long, deep holes in anything from aircraft parts to electric motor rotors.
In 2012 we got the diamond single-point, sine-bar rifling machine out of storage, along with the Pratt and Whitney double-spindle reaming machine. We then completely rebuilt and updated the equipment. We modified the gun-drill to be a counter-rotating drilling system. What that means is the drill spins at about 20% of the rotational speed, and the barrel at 80%. The counter-rotation keeps the drill on the center axis of the barrel more precisely than just rotating the barrel, or just rotating the drill. We are able to consistently drill holes in our barrel steel (primarily 416R) that at the end of a 33.25″ blank that is only .005″ off of center axis.
We then ream the barrels to be .0004″ below desired finish bore size. After the reaming process we mandrel-hone the bores to be .0001″ below finish bore size. This process eliminates reamer marks in the barrel bore. Therefore very minimal lapping is needed after rifling to remove any tooling marks. We then rifle the barrel to any twist rate we like. With a fine lap after rifling, the barrel has no tooling marks and all surface metal is flowing in the direction of the twist of the rifling.
* 7mm BBM stands for “Blake Bramley Magnum”. Dan Bramley and I developed that cartridge together in October of 2017. The .30 BBM is the “Blake Barrel Magnum”, which I developed in May of 2018.
Powder Moisture Content — Did You Know?
Variations in moisture content change the burning rate of a powder and thereby chamber pressures and muzzle velocity. The moisture content of the Vihtavuori N100 and N300 series powders is usually around 1%, while the N500-series’ normal moisture content is 0.6% because of the added nitroglycerine.
So what difference does moisture content make? Here’s an example. In a test, a [Vihtavuori] powder sample was dried by heating it, losing about 0.5 % of its weight. Cartridges were then loaded with the dried powder and fired using a pressure gun. Chamber pressures and muzzle velocities produced by these special cartridges were compared to those produced by cartridges loaded with untreated powder. (The powder charge and bullet were of course the same in both sets of cartridges.)
After Powder Drying:
Pressure Increased 11% from 320 MPa to 355 MPa
Velocity Increased 2.6% from 2526 to 2592 FPS
Comparing results showed chamber pressures increased from 320 MPa to 355 MPa with the dried powder, and the muzzle velocity increased accordingly from 770 m/s to 790 m/s (2526 to 2592 FPS). And note, this is only one example, of one caliber and loading. The difference might be much higher depending on the cartridge and loading combinations.
Recommendation: Store powder below 68°F in 55-65% humidity.
What does this tell us? Well, it seems we need to forget the old saying “Keep your powder dry”! Instead, focus on proper powder storage, at a temperature below 20°C/68°F and humidity between 55 and 65%. Safe reloading everybody!
