Holiday Season Rimfire Fun with 22Plinkster

22 plinkster velocitor CCI Christmas ornament trick shot

YouTube gun video producer 22plinkster has unbridled curiosity when it comes to .22 LR performance. A while back he wanted to see how many Christmas ornaments could be penetrated by one .22 LR round. To answer that burning question, Mr. Plinkster lined up 40 plastic Xmas bulbs in a row and then fired a single round of CCI .22 LR Velocitor ammo through the bunch, using his Henry Golden Boy lever action rifle. Did the bullet penetrate a dozen ornaments? Two dozen? What do you think? Watch the video to find out the surprising answer. The CCI Velocitor ammo is rated at 1435 fps.

Saturday at the Movies: Single-Stage Reloading Press Showcase

RCBS Rock Chucker MEC Marksman Lyman Brass smith ideal Frankford co-ax forster Hornady iron Lee Classic Cast Breech Lock Press

Hand-loaders have never had so many great choices in single-stage presses, with many different configurations and features. There are classic O-Frame presses, Coax-style presses, Open-front presses, Pyramid presses, and compact C-Frame presses. Here is our 2019 Single Stage Press Showcase with products from Forster, Hornady, Lee, Lyman, MEC, and RCBS. We’ve included short videos showing the features of these reloading presses.

If you are shopping for a new press you should look at the various features of each. You may prefer something classic like a Rock Chucker, or the innovative open-front MEC. If you are looking for a compact press to use at the range, the Lyman C-Frame is very impressive for the price. And the Forster Co-Ax remains a great addition to any loading room.

MEC Marksman Single-Stage Press

If you are looking for a new, full-size single-stage reloading press, definitely consider the MEC Marksman. Created by the makers of the popular MEC shotshell reloading systems, the MEC Marksman combines a sturdy cast-iron frame with a modern open-front design. If you are looking for a new, full-size single-stage reloading press, definitely consider the MEC Marksman. Created by the makers of the popular MEC shotshell reloading systems, the MEC Marksman combines a sturdy cast-iron frame with a modern open-front design. With a $239.99 street price, the MEC Marksman press now costs more than an RCBS Rock Chucker Supreme press, but the MEC offers some distinct advantages — such as an open front plus a floating shell-holder system.

MEC Marksman Press Gavin Gear single stage open front press die caddy accessories

Our friend Gavin Gear of UltimateReloader.com got his hands on a MEC Marksman press and put it through its paces. He came away impressed with the product, saying it delivers excellent performance, and has many impressive features. Gavin tells us: “Cast iron tools and machines are a lifetime investment. The made-in-USA MEC Marksman features ductile cast-iron construction, an open-front frame design for easy cartridge access, a new floating shell-holder design with a unique retention system, and ambidextrous handle setup.” MEC also offers a wide selection of accessories for the Marksman press, including a press riser/mount, shell-holder caddy, and die trays.

Forster Co-Ax Press

co-ax forster Hornady reloading single-stage PressIf you are not yet familiar with the many unique features of the Forster Co-Ax, we recommend you watch the video above, a very thorough video review by Rex Roach. This shows how the press operates and highlights the design elements which set the Co-Ax apart from every other reloading press on the market. This 14-minute video shows the key Co-Ax features, explaining how the floating case-holder jaws work (3:30 time-mark), how the dies are held in place (4:40 time-mark), how spent primers are captured (6:10 time-mark), and how to set the primer seating depth (10:00 time-mark). We’ve used a Co-Ax for years and we still learned a few new things by watching this detailed video. If you are considering purchasing a Co-Ax, definitely watch this video start to finish.

In recent years, Forster Co-Ax® presses have been somewhat hard to find, as demand has out-stripped supply. The Co-Ax has many dedicated fans, given its unique features, such as the floating case-holder jaws, and easy, rapid slide-in/slide-out die placement. We’ve also found that Co-Ax presses load very straight ammo and we like the ability to switch between short handle (good for bullet seating) and long handle (ideal for heavy case-sizing tasks). We also think the Forster Co-Ax has one of the best spent primer capture systems on the market — a straight drop into a removable plastic cup. Simple and it works.

Lyman Brass Smith Victory Single-Stage Press

Lyman Brass Smith Victory Single stage press videoLyman’s sturdy Victory Single-stage Press is a full-size unit that competes with the RCBS Rock Chucker Press. With beefy cast iron construction, the Victory’s strength and leverage rivals the Rock Chucker. The press operates smoothly and the handle can be mounted on either side.

If you like to prime cases using a press, this Victory press has a priming system that’s much easier to use than the RCBS Rock Chucker system. The priming tube is right up front, with multiple primers loaded vertically in a tube. Simply push the shuttle at the button of the tube to advance the primer into place.

For convenience, the entire primer-loading system can also be removed so it doesn’t interfere with case and bullet-handling operations. We generally prefer to prime cases separately using a dedicated hand- or bench-mounted tool, but the Victory press does the job nicely.

Overall, the Victory is a great value in a full-size “O-Frame” press with sturdy construction and a solid Lyman warranty. It’s on sale now for $179.99 at Midsouth.

RCBS Rock Chucker Supreme Single-Stage Press

RCBS Rockchucker Rock Chucker Supreme Single Stage reloading press Bruno ShootersNearly every serious hand-loader has owned or used the RCBS Rock Chucker press. This Editor still uses a Rock Chucker passed down by his brother 20 years ago. And yes, it is still going strong. The latest Rock Chucker Supreme single-stage press features an improved “upside-down Y-path” dual-bin spent primer catcher. Otherwise the Rock Chucker Supreme remains big, strong, versatile and sturdy. It has very strong linkages, with a compound leverage system providing plenty of power — FL-sizing is a breeze even with large, magnum cases. The 1″-diameter ram has 12.5 sq. inches of ram-bearing surface.

Some people may not know that the Rock Chucker offers a secondary 1 1/4″ x 12 thread for shotshell reloading dies and Piggyback 3 upgrade. The Rock Chucker Supreme retails for under $190.00 ($169.99 now at Midsouth). The RCBS Rock Chucker is definitely a quality product that can last a lifetime. For heavy-duty sizing chores this remains one of the best choices in single-stage presses. We do recommend shopping around. You can sometimes get a pretty big discount on Rock Chuckers and RCBS has regular rebate programs.

Lyman Brass Smith Ideal C-Frame Compact Press

The Lyman Brass Smith Ideal Press is a very affordable, cast iron C-Frame reloading press. We think it is the new “class leader” in compact presses. This works great as a secondary press for your reloading room or a small press you can take to the range. The large front opening allows you to access the shell holder without hitting the support bar on other types of presses. Unlike other compact presses made from aluminum, Lyman’s Ideal press is cast iron so it is rigid and strong. The high-quality steel ram is one inch in diameter. The Brass Smith is a true ambidextrous press that can be accessed from either side and mounted the same. This is a great choice for a second, auxiliary press for depriming and bullet seating.

Hornady Iron Single Stage (Open-front) Press

In this “Reloading with Rosie” video, the attractive female host loads some ammo using the Hornady Iron Press. With a beefy, pyramid-style cast-iron frame with an open front, this press offers some advantages over a traditional “O-Frame” type press. Access is considerably easier, for one thing. And the top of the press includes slots to hold dies and tools — that’s really a very nice feature that saves time. Also an optional “automatic” priming system shuttles primers from a vertical tube in the back to the shell-holder in the front. That’s clever. Over all the Iron Press is a nice piece of engineering — good job Hornady.

Hornady Iron Press video

Lee Classic Cast (Iron) Breech Lock Press

Lee Classic Cast Breech Lock PressThe Lee Classic Cast Breech Lock Press offers excellent value for the money ($169.99 at Midsouth). Based on the proven design of the Classic Cast press, the updated Breech Lock series adds the quick-change die bushing and an improved primer drop system. This press is strong, with cast iron frame, all-steel linkage, and 12 square inches of ram bearing surface.

Lee says this press has the “largest opening and the longest stroke in the industry” among O-frame type presses. The handle can be mounted on either side. We love the fact that the handle ANGLE can be adjusted, as well as the lever arm length — that allows you to adjust travel and leverage to suit your preference. Smart engineering.

The new spent primer drop features a large-diameter hollow ram with clear hose that drops primers straight to a bin — that’s simple and effective. The press is very rigid and the base is wide enough for good stability. We have one of these Classic Cast Breech Lock Presses in our reloading room and it works well.

Protect Your Valuable Firearms with Long Gun Cleaning Mats

rifle shotgun cleaning mat pad rush creek DryMate Boyt Harness
This deluxe, roll-out Rush Creek Creations 42-0000 69″ x 16″ gun cleaning mat (with pockets), is available from Tractor Supply for $76.49.

We normally use a gun cradle when cleaning or adjusting our rifles. But there are situations, such as when working on a barreled action, when it’s nice to use a pad that lies flat. Many work pads are too small — they’re nothing more than oversize mouse pads. Here are three gun pads that are big enough to work well with rifles and/or barreled actions.

DryMate Gun Cleaning Pad

rifle Gun cleaning pad drymateThe Drymate Gun Cleaning Pad is a full 59″ x 16″. That’s nearly five FEET from end to end — longer than most rifles, so you have plenty of surface area for working. Conveniently, this product can be washed with soap and water. It is offered in Green and Charcoal Gray colors. We prefer the Green version because the color makes it a bit easier to see small black and gray parts such as screws and springs.

Boyt Harness Counter Pad

The 48″ x 12″ Boyt Harness Counter Pad was originally designed more for display purposes than for serious work sessions, but we like this product. It is useful if you want to lay your gun on a bench to make small adjustments. The Boyt Counter Pad, $25.99 at MidwayUSA, is nice and big, a full four feet from end to end. The back side is canvas while the top-size is a quilted cotton fabric. This product has received high praise from buyers. Here are actual owner reviews:

rifle Gun cleaning pad drymate

Worth every penny. I bought three of them because I want to have at least one always around. I use one for a shooting bench or tailgate mat and another for my primary gun cleaning workbench mat. Awesome for both purposes. This one was perfect for my array of needs. — Joe D.

This mat is great for cleaning guns and keeping your surfaces clear of oil or solvent. The mat has plenty of space for a rifle or handgun and the padding is thick enough[.] I would definitely buy again and have recommended this to my friends and family. — Safety Guy

I bring this to the rifle range with me every time, to rest my rifle on the table without worrying about scratches. It fits nicely in my soft rifle case. One side is a tough canvas material that doesn’t show scratches, and the other side is a soft fleece material that protects the finish of your gun. — MACPSU


Hoppes Gun Cleaning Pad

rifle Gun cleaning pad drymateThe Hoppes Gun Cleaning Pad is 36″ wide x 12″. That’s big enough for many barreled actions (unless you have a really long barrel). This pad has a non-slip nylon backing, and Hoppes claims that the “Soft acrylic material absorbs 8 times its weight in fluids.” This Hoppes Cleaning Pad is very affordable. It costs just $10.95 at Amazon.

Even with Suppressed Firearms Hearing Protection is Important

suppressor silencer moderator facts fiction sound levels noise decibles dB
Silencer-equipped AR photo courtesy The Silencer Shop.

OK, you’ve paid the tax stamp and acquired your new suppressor (aka “silencer” or “moderator”). Do you still need to wear earplugs or muffs? Absolutely. Even with that expensive new “can”, your rifle could be generating over 140 decibels (dB) of noise — about the same as as an unmuffled 9mm pistol shot. That’s loud enough to create permanent hearing loss with repeated exposure.

Firearms Are Loud: 140 dB to 175 dB

Audiology group ASHA explains: “Exposure to noise greater than 140 dB can permanently damage hearing. Almost all firearms create noise that is over the 140-dB level. A small .22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss. Also, adding muzzle brakes or other modifications can make the firearm louder. People who do not wear hearing protection while shooting can suffer a severe hearing loss with as little as one shot[.] Audiologists see this often, especially during hunting season when hunters and bystanders may be exposed to rapid fire from big-bore rifles, shotguns, or pistols.” Source: ASHA, Recreational Firearm Noise Exposure.

suppressor silencer moderator facts fiction sound levels noise decibles dB

Suppressors, On Average, Reduce Noise Levels about 30 Decibels
In an article for Ammoland, gunwriter Sam Hoober says that you can expect about 30 decibels (dB) of noise reduction from the average suppressor: “Looking at a few different products, SilencerCo attests their suppressors reduce the sound pressure of a 9mm gunshot to anywhere from 125.7 dB to 131.5 dB, depending on the model. Advanced Armament Co, another popular supplier, attests a 23 dB to 33 dB reduction or down to 127 dB. Liberty Suppressors, another manufacturer, attests a reduction of 24 dB to 38 dB, depending on model and other factors. In short, we can presume something on the order of 30 dB of attenuation as an average.”

Using that 30 dB number you can quickly discern that you’ll still need hearing protection — good hearing protection — when shooting any suppressed firearm (even a .22 LR). “Spikes of 130 dB and more can result in permanent hearing damage instantly”. Source: NRA Blog.

The Myth of the “Quiet” .22 LR
The NRA Blog notes that “many rimfire shooters, particularly those using the beloved .22 Long Rifle cartridge, argue that the small .22 LR caliber doesn’t produce enough sound to damage your hearing”. So, is that really true. or is it a myth?

In fact, a .22 LR can be much louder than you think — a .22 LR pistol can produce sound levels of 134 dB. That’s well above the normal human pain threshhold.

Sound Levels for Common Noises:

9mm Luger pistol: 160 dB

Jet aircraft engine (near): 140 dB

.22 LR pistol: 134 dB

Normal human pain threshold: 120 dB

Noisy Nightclub: 110 db

Riding Motorcycle at 65 mph: 103 db

Power Lawnmower: 95 dB

Hearing damage possible: 85 dB (sustained for 8+ hours)

Ringing Telephone: 80 dB

Normal conversation: 60 dB


The Risk of Hearing Loss
Hearing loss can be progressive and irreversible. If you are a shooter, this is serious business. As the NRA Blog cautions: “You may not even realize you’re harming your hearing. Hearing loss occurs gradually, and can go effectively unnoticed until symptoms become severe. By then, the damage is done.”

Nobody wants to go deaf. But we often see shooters without effective hearing protection when they are walking around a few yards behind the firing line. That’s bad — even if you are away from the firing line, gunshot noises can damage your hearing. You MUST use effective hearing protection every time you go to the range. Good foam earplugs costs mere pennies but they can prevent deafness in your later years. Many folks also wear muffs over plugs.

Stocking Stuffers for December 2022 — 15 Selections

AccurateShooter.com stocking stuffer tools

Christmas is just nine days away, so today we’re featuring a hand-picked collection of “stocking stuffers” for precision shooters. Some of these are recent inventions. All are handy items that you’ll use over and over again at the range, on your vehicle, and/or at your loading bench (so you’re allowed to buy them for yourself, even after Christmas).

Cabela’s Multi-Tool — $7.99

Cabela's Multi-tool blank stocking stuffer

You won’t find a more versatile tool at this low price — just $7.99. The Cabela’s multi-tool performs many functions.

This handy tool is available in five colors: Red, Teal, Orange, Silver, and Green. A durable nylon belt sheath protects and carries the multitool.

B&T Industries BT62 Determinator — $7.95

Group Size Measuring plate Determinator

The acrylic BT62 Determinator measures groups with laser-cut concentric measuring rings. Check group size quick and easy — simply place the Determinator over shot group. Adjust until one of the circles crosses the center of the two outer-most holes. That gives you the center to center group measurement (1.5″ maximum). Alternatively, you can measure edge to edge (of the farthest shots) and then subtract the bullet diameter. Cool tool for gun guys. The supplied lanyard also glows in the dark.

JKL Precision — LabRadar Recoil Pulse Trigger — $35.00

labradar inertial recoil trigger

Frustrated with your LabRadar missing shots? With this $35 LabRadar Recoil Trigger you will be much happier — and you won’t get false readings from the guy on the next bench. This plug-in device, made by JLK Precision, activates the LabRadar from your rifle’s inertial recoil pulse. It will work with any rifle from a .22 LR up to the big magnums. NOTE: The inertial trigger is sensitive so a “phantom” reading may occur with hard bolt manipulation. However, our Forum members who use this trigger say it is is a great improvement, with no more LOST shots and LabRadar placement is no longer critical. One owner noted: “This unit works flawlessly. Didn’t miss a single shot, and allows you to place the LabRadar in pretty much any position.” Velcro attachment standard — Picatinny and magnetic mounts sold separately. This trigger is made by JLK Precision, NOT by the LabRadar company.

How Cut-Rifled Barrels Are Made — History of Cut-Rifling Process

Pratt & Whitney Cut rifling hydraulic machine

You’ve probably heard of cut-rifling, but did you know this process was invented in Germany nearly 500 years ago? Read on to learn more about how a cut-rifled barrel is made…

The cut-rifling process, used by leading barrel-makers such as Bartlein, Blake, Brux, and Krieger can yield a very high-quality barrel with a long useful life. Cut-rifled barrels have been at the top in short- and long-range benchrest competition in recent years, and cut-rifled barrels have long been popular with F-Class and High Power shooters.

You may be surprised to learn that cut-rifling is probably the oldest method of rifling a barrel. Invented in Nuremberg around 1520, the cut-rifling technique creates spiral grooves in the barrel by removing steel using some form of cutter. In its traditional form, cut rifling may be described as a single-point cutting system using a “hook” cutter. The cutter rests in the cutter box, a hardened steel cylinder made so it will just fit the reamed barrel blank and which also contains the cutter raising mechanism.

Above is a computer animation of an older style, sine-bar cut-rifling machine. Some machine features have been simplified for the purposes of illustration, but the basic operation is correctly shown. No, the cut-rifling machines at Krieger don’t use a hand-crank, but the mechanical process shown in this video is very similar to the way cut-rifling is done with more modern machines.

Kolbe Border Barrels Firearms ID

Read About Cut-Rifling Process at FirearmsID.com
To learn more about the barrel-making process, and cut-rifling in particular, visit FirearmsID.com. There you’ll find a “must-read” article by Dr. Geoffrey Kolbe: The Making of a Rifled Barrel. This article describes in detail how barrels are crafted, using both cut-rifling and button-rifling methods. Kolbe (past owner of Border Barrels) covers all the important processes: steel selection, hole drilling, hole reaming, and rifling (by various means). You’ll find a very extensive discussion of how rifling machines work. Here’s a short sample:

“At the start of World War Two, Pratt & Whitney developed a new, ‘B’ series of hydraulically-powered rifling machines, which were in fact two machines on the same bed. They weighed in at three tons and required the concrete floors now generally seen in workshops by this time. About two thousand were built to satisfy the new demand for rifle barrels, but many were broken up after the war or sold to emerging third world countries building up their own arms industry.

Pratt & Whitney Cut rifling hydraulic machine

Very few of these hydraulic machines subsequently became available on the surplus market and now it is these machines which are sought after and used by barrel makers like John Krieger and ‘Boots’ Obermeyer. In fact, there are probably less of the ‘B’ series hydraulic riflers around today than of the older ‘Sine Bar’ universal riflers.

The techniques of cut rifling have not stood still since the end of the war though. Largely due to the efforts of Boots Obermeyer the design, manufacture and maintenance of the hook cutter and the cutter box have been refined and developed so that barrels of superb accuracy have come from his shop. Cut rifled barrel makers like John Krieger (Krieger Barrels), Mark Chanlyn (Rocky Mountain Rifle Works) and Cliff Labounty (Labounty Precision Reboring)… learned much of their art from Boots Obermeyer, as did I.” — Geoffrey Kolbe

Video find by Boyd Allen. Archive photos from Border Barrels. In June 2013, Birmingham Gunmakers Ltd. acquired Border Barrels. Dr. Geoffrey Kolbe has set up a new company called BBT Ltd. which produces chamber reamers and other gunsmithing tools and gauges. (Thanks to L. Holland for the Kolbe update).

Planning to Gift a Gun? Learn the Laws Before You Buy

firearm gun gift law rules NSSF

‘Tis the season of gift-giving (Christmas Day is 8 days hence). Perhaps you’re considering giving a a first rifle to your grandson or perhaps a carry pistol to a spouse. When making a gun gift to a friend or family member, however, there are some very important legal considerations. Also the rules on firearms gift transfers vary from state to state. Bottom line here — you need to know the law BEFORE you deliver that shiny new firearm to a family member, close friend, or relative.

The first thing to remember if you’re thinking about giving someone a gun is that … it’s a gun! You already know that ownership of a firearm brings with it some serious legal and ethical obligations that other consumer products don’t. So let’s look at some questions you may have about giving a firearm as a gift.

firearm gun gift law rules NSSF

ATF Firearms gun giftsThe first question you have to ask is whether the intended recipient can legally own the firearm where he or she lives. With more than 20,000 different gun laws on the books, even the kinds of firearms that law-abiding citizens can own vary from place to place. For example, juveniles (under age 18) generally speaking are precluded by law from possessing a handgun. Check out the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) website for an overview of local laws and, whatever you do, don’t forget that you can never under any circumstances transfer a firearm to someone you know — or have reasonable cause to believe — legally can’t own one. That’s a federal felony, so be careful.

There’s no federal law that prohibits a gift of a firearm to a relative or friend who lives in your home state. Many states — including California, Colorado, Connecticut, Delaware, New York, Oregon, Rhode Island, Washington State and the District of Columbia — require you to transfer a firearm through a local FFL-holder so an instant background check will be performed to make sure the recipient is not legally prohibited from owning the gun. Maryland and Pennsylvania require a background check for private party transfer of a handgun. And yes, Oregon has new restrictions due to the passage of Ballot Measure 114 (though a State Judges has issued an injunction blocking some provision BM 114). There are exceptions, so it’s important to check the law of your state or ask your local firearms retailer.

The ATF recommends that if you want to give someone a new firearm, rather than going to a gun store and buying the gun on your own, consider instead purchasing a gift certificate/card from your favorite gun retailer. Then give that gift card as the present. That way the recipient can choose the exact gun he or she wants, and there’s no question about who is “the actual buyer of the firearm”, which is a question any purchaser must certify on the Federal Form 4473 at the time of purchase. The Gift Card option avoids any “straw purchaser” issues.

And right now you can earn a “bonus” for giving a gift card. Brownells is running a promotion. For every $100 you give in Brownells Gift Cards you get a $25.00 gift card for yourself. That’s essentially a 25% Bonus for your generosity. You can have the Brownells Gift Card mailed directly to the lucky recipient. Or, if you’re running low on time, you can have electronic Gift Card sent via email. CLICK HERE for details.

Intra-Family Transfers and Antique Arms
What if you want to give “Old Betsy,” your favorite old deer rifle, to your son or daughter as a college graduation gift? Again, in some states, there’s no law that says you can’t, but many states require even intra-family transfers to go through a licensed dealer. Remember, you can never transfer a firearm directly to another person who is a resident of a different state. In that case, you must transfer the firearm through a licensed dealer in the state where the person receiving the gift resides.

Using a gift certificate from a firearms retailer near where the recipient lives might be a good solution. Be safe and check with an in-state FFL dealer before you give any firearm to a friend or family member.

IHEA-USA Offers Firearms Fundamentals Training Courses

IHEA Rifle handgun shotgun pistol fundamentals safety online training

The International Hunter Education Association (IHEA-USA) now offers low-cost online Firearm Fundamentals courses for gun owners. The new IHEA-USA online training program provides separate online courses for Rifles, Shotguns, and Handguns, each priced at $12.00:

Rifle Fundamentals | Shotgun Fundamentals | Handgun Fundamentals

These programs were developed by the IHEA-USA to meet the nationally growing demand for accessible firearms safety education. These courses were crafted with input from the U.S. Fish and Wildlife Service, state hunter education staff, volunteer hunter education instructors, and professional hunters.

IHEA Rifle handgun shotgun pistol fundamentals safety online training

IHEA-USA Firearm Fundamentals include modules on firearms safety best practices, responsibilities as a firearms owner, safety in the home, storing and transporting firearms, specific information on safe handling of types of firearms, ammunition, locks and safes, range safety and etiquette, firearms care and cleaning as well as introductions to using firearms for hunting and sport shooting. The course also teaches new firearms owners about Pittman Robertson funding and how their purchases contribute to wildlife management in America.

“It made perfect sense for us to address general firearms safety for the thirteen million new firearms owners coming into the marketplace over the last two years … we believe that all new firearms owners can benefit from these introductory training modules”, states IHEA-USA Executive Director Alex Baer.

The Firearm Fundamentals course also offers all participating states the opportunity to introduce new firearms owners to hunting, local ranges, sport-shooting, and other firearms-related activities in their states upon completion of the course. For more information on IHEA-USA programs and initiatives, contact sponsorship@ihea-usa.org.

Could You Shoot 0.8 MOA at 300m — for FIVE HUNDRED Shots?

Sierra Bullets 500 round tunnel test

For load development, some guys shoot 3-shot groups. Other guys shoot 5-shot groups, or even 10-shot strings. But for testing its projectiles, Sierra Bullets takes it to another level entirely. A while back Sierra was testing its .30-Caliber 175gr HPBT MatchKing in the Sierra underground tunnel. The results appear above — a FIVE HUNDRED Round group!

500 Shots Form 0.82 MOA Group at 300m (328 yards)
Sierra’s trigger-pullers sent five full boxes of bullets down-range at a single target. The photo above shows the result of 500 shots taken in a 300 meter test tunnel. The raw group size, edge to edge of the farthest shots, is about 3.13 inches, as shown on the calipers’ metal linear scale. Subtract a .308″ nominal bullet diameter* to get the 2.823″ on the digital readout. So you’re seeing a 2.823″ group at 300 meters (328 yards). One MOA at this distance is 3.435″ so this 500-round group is 2.823 divided by 3.435 or 0.82 MOA (0.8218 MOA to be precise).

This 500-round group was shoot as part of a pressure/velocity test for a commercial customer. The cartridge was .308 Winchester, loaded at 2.800″. The powder was Reloder 15. A 26″ barrel was shot from a return to battery rest. The gun was cleaned every 125 rounds and two foulers shot.

What do you think — could you beat this group from a bench for 500 rounds?

One Facebook poster joked: “500-round group? Everyone knows anything less than 1000-round groups are a waste of time and statistically irrelevant.”

Sierra’s 300 Meter Testing Tunnel
Ever wonder how (and where) Sierra tests its bullets? The answer is underground, in a 300-meter test tunnel located under Sierra’s factory in Sedalia, Missouri. The photo above shows the construction of the tunnel back in May, 1990. Like most bullet manufacturers, Sierra does live-fire bullet testing of its projectiles. Sierra’s 300-meter test range is the longest, manufacturer-owned underground bullet test facility in the world. In years past, Sierra offered free visits to the test tunnel as part of a factory tour.

* Normally, to get an exact group size, you should subtract the TRUE bullet hole size, which is usually smaller than the nominal bullet diameter. E.g. a .308 bullet hole may show on paper as .298 or so. But here, for simplicity, we are subtracting .308″ because we do not have the original target to measure.
