Sunday GunDay: Summer Varmint Hunts — Guns, Ammo, Planning

sunday varminting Varmint Bullet 17 hmr 6mmBR Prairie dog

It’s the height of summer now, just two weeks after the nation’s 250th birthday on July 4th. Will you head to the varmint fields this summer? Proper planning is key to a safe, satisfying, and productive varmint holiday. Definitely make a check-list of all the gear and supplies you need. Bring a variety of rifles if possible — you’ll need to switch off as one barrel gets hot, and the chambering that works best for your close shots may not be ideal for those longer shots out past 400 yards.

Here are some tips from our Forum members that can help you shoot more effectively, and avoid problems on your varmint hunt. Here’s one key tip: at your shooting station, put a strip of surveyor’s tape on a tall stake to show the wind direction. Then shoot in the direction the wind blows. This will minimize the effect of cross-winds.

Varmint Safari Planning, Equipment, and Shooting Advice

From PatchHound: “The gear you bring will make or break a trip out to Prairie Dog land. A lot has to do with where you going and how far you are from [civilization]. For starters, bring lots of water. It will be hot in Wyoming in a few more weeks but it don’t hurt to bring warm clothes in case it snows. It’s best to wear leather boots unless you’re real good at dodging cactus while walking around. Good sunscreen [and a wide-brimmed hat] will save the day too. [What you need to bring] really depends on whether you’re shooting on some friendly ranch or 100 miles in the middle of [a wilderness area]. Good survival gear is a good thing to have for the latter!”

From Stoner25mkiv: “I’d suggest an adjustable bipod if you are going to do any walking. A laser rangefinder is a huge asset. Have a fanny pack or backpack for extra ammo, water, bore-snake, etc. when you go on your walkabouts. We also take a couple pivoting benches, heavy movers’ pad/blanket, sandbags (Uncle Bud’s Bulls Bag) for shooting from near the vehicle. Boonie hat for blocking the sun, sun glasses, sunscreen. High leather boots.

From CTShooter: “The .204 [Ruger] is a laser beam and good to 400 yards easy. Forget the rimfire! Do you have a portable bench that pivots? Bring bipod, binocs. Bring a LOT of water. I have a milspec sniper shooter’s mat/drag bag with shoulder straps. It is good to carry everything when you want to wander off and shoot prone with bipod. Here’s a view through my 6BR in ND.”

From RJinTexas: “In most of the locations that we’ll be shooting we’ll usually set up a minimum of 200 yards from the edge of a major dog town. We’ll start by working over the close-in dogs and shooting our way out, some of these towns may run in excess of 500/600 yards deep. [A .204 Ruger] will work well out to 300/400 yards unless the wind is blowing hard. We classify a 10-mph crosswind as a very calm day and what makes it a little more challenging is that it is usually also gusting.”

From Wes (P1ZombieKiller): “[For my first PD trip] there are so many things I was not ready for. The one thing that I did bring (that no one told me about) was a canopy. I’m glad I did. Even though the weather was [near perfect], I know that sun can humble you real fast. With my pop-up canopy, I could shoot all day without getting killed by the sun. You had to tie the canopy down real well or the wind would blow it across the pasture.

We sat on shooting benches that pivot 360°, and are fast and easy to set up. Most all shots were 175-250 yards. I just felt comfortable at that range. It was more fun for me to be able to film the hits, and the camcorder I was using just did not get good video past 350 yards. The digital zoom distorted the image too much. I knew I would only get this one chance to film my first P-dog outing, and I wanted to get it on film for [posterity].”

Bring Multiple Rifles on Your Varmint Adventures

On our P-Dog adventures, we like to have multiple rifles — a .17 HMR for close work, then maybe a .20 Practical AR for 150-250 yards, then a larger caliber such as 22 BR, 6BRA, 6 Dasher or 6-6.5×47 for those long shots. The classic .22-250 is also a wickedly effective varmint cartridge.

Prairie dog adventure varmint hunting

Popular Varmint Rifle Chambering Options: .17 HMR, .17 WSM, .20 Practical, .204 Ruger, .223 Rem, .22 BR, 6mmBR, 6mm BRA, 6mm Dasher, 6-6.5×47 Lapua, 6 Creedmoor, 6XC, .243 Win.

.17 HMR Savage A17 Varmint Rifle

We like to have a Rimfire varmint rig for the closer shots, inside 150 yards. The .17 HMR or .17 WSM are good choices. With a rimfire you save on ammo costs and you don’t waste precious centerfire barrel life. This video shows a successful Prairie Dog hunt with a .17 HMR. Watch and you’ll see hits out to 160 yards (00:50), proving the effective range of the 17 HMR cartridge. The host is shooting a Savage A17 semi-auto 17 HMR rifle in a Boyds laminated stock.

.17 WSM Rimfire in Franklin Armory F17-L

What’s the ultimate rimfire varmint rifle? An AR chambered for the .17 WSM could be the answer. Eric Mayer of Varminter.com states: “The Franklin Armory F17-L in .17 Winchester Super Magnum (WSM) has a lot of firsts. It is the first semi-automatic rifle in .17 WSM now available to the general public. It is the first gas-piston system, AR-15 rimfire rifle built in partnership between Franklin Armory and Osprey Defense.”

Eric has used the .17 WSM AR shooting ground squirrels, rock squirrels, prairie dogs, and rabbits. Eric notes: “The report of the .17 WSM is nowhere near as loud as most of the centerfire [varmint] cartridges. I found that when I shot the FA-17, it did not cause the other ground squirrels… to run for cover. The lack of recoil … allowed me to see right where I hit [and] if I happened to miss, [low recoil] made for quick corrections for wind, or distance.” READ Full Report

The .17 WSM is a much larger, more powerful round than the .17 HMR. See the size difference above.

.20 Practical (20-223 Rem) AR-Platform Varminter

Here is a .20 Practical built by Robert Whitley. Whitley’s Ultimate Prairie Dog Rifle (PDR) features a 24″ Bartlein 1:11″-twist cut-rifled barrel, DPMS side-charging upper, and a Jewell trigger. It is chambered in 20 Practical, a cartridge popularized by Warren “Fireball” Brookman.

varmint hunting prairie dog dakota dogtown

This .20 Practical cartridge is simply the .223 Remington necked down to .204. You can use your existing .223 Rem brass — no special case-forming required! The 20 Practical is accurate, flat-shooting, and has almost no recoil. The advantage over the standard .223 Remington is that, grain for grain, the bullets have a higher BC and travel at a higher velocity for more dramatic effect on a small varmint. The ultra-low recoil allows you to easily see your hits, even without a muzzle brake. The 20 Practical, launching 40-grainers at about 3750 fps, shoots flatter than a .223 Rem with 55gr hollowpoints.

.204 Ruger AR-15 (Suppressed) for Cottontail Rabbit Hunting

As a varmint hunting tool, the .204 Ruger in an AR-15 is a versatile, worthy cartridge/rifle combo for the job. This video covers a cottontail rabbit hunt. The host states that “We were contacted by a farmer who was being slammed with cottontail rabbits eating out huge portions of his alfalfa fields.” This suppressed .204 Ruger AR-15 proved seriously effective on the rabbits, driving high-velocity rounds with impressive accuracy. See more details on the Varminter.com website.

.22 BR Savage Varminter — Accuracy on a Budget

AccurateShooter.com Pride Joy 22 BR savage varmint rifle ground hog 6mmBR
AccurateShooter.com Pride Joy 22 BR savage varmint rifle ground hog 6mmBR

This .22 BR Savage, with upgrades from Sharpshooter Supply, is the “pride and joy” of Forum member Maynard. Note the heavy-contour custom barrel with brake. That .22 BR cartridge is a very effective choice for varmint work, as the ground hog in the photo proves. The .22 BR and .22 Dasher are capable of outstanding accuracy with a large variety of bullets and powders. A .22 Dasher can rival the ballistics of a 6mmBR out to 500+ yards, but with reduced recoil.

Avid varmint hunter Bill White (aka “CT10Ring” in our Forum) concurs about the effectiveness of the .22 BR Cartridge: “.22 BR — My .22 BR is my first choice for most prairie dog missions. Accuracy is superb with necked-down 6mmBR Lapua brass — quarter-MOA and blazing fast. With the right twist rate, this chambering can shoot anything from 40gr FB bullets to 80gr VLDs. Load development is easy. Below is my .22 BR ammo for another varmint trip. I use 55gr Sierra BlitzKings with Varget in my 1:12″-twist Shilen-barreled rifle. 60gr Bergers are very accurate with a fairly flat trajectory for useful distances.”

6mm Dasher for Voldoc’s 2024 Prairie Dog Safari

CFE 223 Powder Varmint Bullet Prairie dog

6mm DasherRespected Forum member Voldoc has a long thread about his 2024 Prairie Dog Safari, his 20th trip of this kind. He reported: “After the 1st day of shooting with 30+ MPH wind, we settled down on a High Point, and set up the Benches the second day for a ‘Shooting Gallery’ of non-stop shooting. PDogs were in play from 125 to 1,000 yards.” Voldoc’s rifle features these components: Nesika J RBRP action, 1:12″-twist Krieger barrel chambered by Mike Bryant for the 6 Dasher, 2 oz. Jewell trigger, Thunder Beast Suppressor, Nightforce ATACR 7-35X FFP optic. He usually shoots 87gr V-Max bullets in annealed Lapua brass pushed to 3240 FPS by Vihtavuori N135 powder. To spot critters, Voldoc uses Vortex Fury 5000 AB Rangefinding Binoculars.

More Power — 6-6.5×47 Lapua for Longer Range Varmint Shots

6mm 6.5x47 Lapua 6-6.5x47 varmint rifle mcmillan BAT action 6mmAI

Soon after Lapua released the 6.5×47 cartridge, wildcatters recognized the potential of a necked-down 6mm version of the case. The 6-6.5×47 has emerged as a great, do-it-all cartridge that performs well in High Power competition, 600- and 1000-yard benchrest, and PRS tactical matches. But the 6-6.5×47 is not just for paper-punching. An efficient cartridge with great inherent accuracy, the 6-6.5×47 can be an excellent, flat-shooting, long-range varmint round. Here we feature Stan Stewart’s BAT-actioned 6-6.5×47 varminter. Fitted with a Krieger 1:10″ barrel, Stan’s rifle excels with a wide variety of varmint bullets. Whether driving 70-grainers at 3700 fps, or pushing the Berger 88gr High-BC FB bullet at 3400 fps, this 6-6.5×47 delivers half-MOA (or better) accuracy, in a well-balanced, easy-handling rifle. He has developed very accurate loads with Varget, Vihtavuori N550, and Reloder 15.

Six Tips for Novice Long Range Varmint Hunters

Bill white varmint hunting North South Dakota Wyoming 6x47 6.5-284 22BR .204 Ruger

1. Take twice as much ammo you think you may need. The fields could be particularly rich, or, because of wind or other variables, you may have far more misses than expected.

2. When possible, set up with the wind at your back (or, alternatively, directly ahead). This will minimize the effect of cross-winds. Set up a stake with a ribbon to show wind direction.

3. Bring at least two rifles. Ideally one would be a low-recoil rifle with cheaper components for the closer shots. Then bring a rifle with higher-BC bullets for longer shots where wind is a bigger factor.

4. Check the weather before you head out. Prairie dogs like sunshine and calm conditions. If a cloudy, very blustery day is predicted, considering staying in town and cleaning the rifles.

5. Bring plenty of water on a trip. An adult male should be drinking at least 64 ounces of water (or other liquid) every day — more if it’s very hot or you are sweating a lot.

6. Preferably always hunt with a companion. If you do go out solo, have a Garmin inReach SatComm/GPS for emergencies if there is no cell coverage in your location.

A Dozen Handy Items Recommended for Your Range Kit

Range Kit Gear shellholder safety dozen essentials

The shooting season is now in full swing. When you head to the range you’ll want to be prepared. That means collecting all the gear you’ll need at the range. It’s easy to forget small, critical items, so we’ve provided a checklist of the small “extras” you should pack before you head out to the range. In addition to rifle, rests, ammo, targets, and cleaning gear, here are a dozen essentials you should include in your range bag.

Shell-Holder — If you don’t have calipers, you can use a shell-holder to check for excessive case expansion from hot loads. If a fired case doesn’t slip into the shell-holder easily, your load is definitely TOO HOT.

Extra Earplugs — Always use ear protection when shooting. We bring a 35mm film canister with extra sets of foam earplugs.

Hex Wrench or Screwdriver for action screws — Action screws can work loose with time. Always bring the appropriate hex wrench or screwdriver whenever you go to the range.

Small Wrench for Scope Rings — Check the tension of your scope base and ring fasteners before you go. Bring along a small Torx wrench for the ring screws (or other tool that fits your fasteners).

Normal and Under-sized Jags — It is often wise to use one-caliber undersize jags when applying solvent with cotton patches. You should have a couple sizes in your range kit.

Extra Batteries — Bring extra batteries for all your electronic gear — which can include chronograph, windmeter, digital camera, GPS etc.

Small Notebook and Pen or Pencil — Use the notebook to record chron data, log group sizes, and make notes about wind and weather conditions.

Adhesive dots — Bring a few sheets of adhesive dots (sold at office supply stores). Use small white or black dots as target pasters. Use larger red or orange dots as aiming points (target centers).

Folding Chair or Camp Stool — This comes in handy if you’re spotting for another shooter, or if you reload away from the firing line.

Water Bottle — You can’t shoot well if you’re dehydrated. Bring at least two quarts of water with you and keep a bottle at the bench.

Surveyors’ Tape and Wood Stakes — You can make inexpensive wind indicators using surveyors’ tape attached to the top of wood stakes.

Small Plastic Ruler — Use this to measure your group sizes. A transparent (see-through) ruler works best. Rulers are also useful for drawing lines on targets.

This list is not intended to be exclusive. There are many other items you may wish to include. Obviously bring safety glasses, and Sharpie-type pens are always handy to mark targets. We invite our readers to add other “essentials” to the list. The important thing is to plan ahead, packing your key items before you drive to the range.

17 Mach 2 — Affordable 2050 FPS Rimfire Alternative to 17 HMR

17 mach 2 .17 hm2 17HMR volquartsen summit

The 17 Mach 2 (aka “17 HM2″) is making a come-back. We’re glad. This high-velocity round fits actions and magazines designed for the .22 LR, so it’s an easy barrel-swap upgrade for most rimfire bolt-guns (semi-autos are more complicated). The 17 Mach 2 cartridge doesn’t deliver the velocity of the 17 HMR, but it is still way faster than a .22 LR. Expect 2000-2100 fps with 17 Mach 2 compared to 1250 fps for “High-Velocity” .22 LR ammo. And, importantly, 17 Mach 2 ammo is much less expensive than 17 HMR. If you shop around, you can get 50 rounds of 17 Mach 2 for about $8.50 (or less). That’s 43% cheaper than a better-than-average $14.99 price of 17 HMR — a significant savings at 17 cents/round vs. 30 cents/round! And may vendors are selling 17 HMR ammo for $16-$18 for 50 rounds (i.e. up to 36 cents/round).

17 Mach 2 Major Selling Points:

1. 60% more velocity than typical “High-Velocity” .22 LR ammo.
2. 40% less cost than average 17 HMR ammo.
3. 17 Mach 2 OAL is compatible with .22 LR receivers and magazines.

17 Mach 2 — Best High Velocity Rimfire Bang for the Buck?

If you are looking for a capable, squirrel-busting round or a fun plinking round, you should definitely consider the 17 Mach 2, especially since CCI has committed to production of the little cartridge. CCI recently rolled out its “Gen 2″ 17 Mach 2 VNT Ammo with polymer tip (see top of article).

Considering that 17 HMR ammo is typically $15 to $18 per box, the 17 Mach 2 is a good value by comparison. It is available from vendors for under $8.50 per 50ct box. That’s $0.17 per round. When you consider overall “bang for the buck”, for many shooters, it makes sense to use the 17 Mach 2 rather than a 17 HMR. You save money, barrel life is a little longer, and the 17 Mach 2 is still a much more potent cartridge than the .22 LR. Check out this comparison, and note how the 17 Mach 2 has a much flatter trajectory than the .22 LR. For varmint shooting, the 17 Mach 2 is clearly the better choice.

And you can easily adapt a .22 LR Rifle to shoot the 17 Mach 2 just by changing the barrel. The magazine and bolt operation should work as the cartridge length, cartridge body diameter, and rim size is the same as the .22 LR.

17 Mach 2 hm2 .22 LR comparison
Hornady’s 17 Mach 2 has a 2100 FPS muzzle velocity vs. 1255 FPS for “High-Velocity” .22 LR.

17 Mach 2 Rifle Reviews

Gun-makers have taken notice of the availability of 17 Mach 2 ammo, introducing new models chambered for this versatile little rimfire round. For a high-volume, small-species varminting, the 17 Mach 2 is much more effective than the .22 LR, and much less expensive than the larger 17 HMR.

Savage A17 in 17 Mach 2

There are a number of reviews on new-generation 17 Mach 2 rifles. Varminter.com reviewed the Savage A17 in 17 HM2. Editor Eric Mayer wrote: “This new addition to the A17 line comes at a time when the 17 Mach 2 round is experiencing a resurgence, with ammo now available from CCI and Hornady, including the lead-free NTX round from Hornady. This means … you don’t have to break the bank to buy a current, functioning, semi-auto 17 Mach 2 and you don’t have to … convert your 10/22.”

17 mach 2 .17 hm2 savage a17 17 HMR varmint rimfire summit

Eric shot four different types of 17 Mach 2 ammo, putting 1000+ rounds through the Savage. He was impressed: “I am very excited that Savage Arms has chambered their A17 rifle in the 17 Mach 2 / 17 HM2 round. After shooting the prototype, I can confidently say that this new A17 will become my go-to 17 Mach 2 rifle. This new rifle is a great option for varminters everywhere!”

Toggle Bolt Volquartsen Summit in 17 HM2

It’s rare for us to see a rimfire that we’d really like to own, but the Summit from Volquartsen fits the bill. This versatile rifle features a cool, straight-pull toggle bolt, similar to those on elite Biathlon rifles. You can see how this gun shoots in this informative 22 Plinkster video:

22 Plinkster Tests Volquartsen Summit Rifle in 17 Mach 2

The 17 Mach 2 (17 HM2) is making a comeback. Now leading manufacturers are offering this efficient little rimfire cartridge in some nice rifles. Both Anschutz and Volquartsen will offer new 17 Mach 2 rifles in 2019. The Volquartsen Summit features a lightweight, carbon fiber-wrapped barrel threaded 1/2-28 for brakes or suppressors. The Summit boasts a nice 1.75-lb trigger pull. The Summit’s CNC-machined receiver features a +20 MOA Rail. NOTE: The video shows a silhouette-style laminated wood stock. However, the Summit comes standard with a composite Magpul stock that actually works better for shooting from a bench.

Powder Inflation — Price of Powder Now vs. 48 Years Ago

historic hodgdon powder prices inflation chart table O.K. Weber

Have inflation (and supply chain shortages) affected the price of powder? You bet. Probably WAY more than you could imagine. Forum member “Two Time HM LR” posted this interesting photo (above) showing Hodgdon powder prices from 1978, as sold by O.K. Weber in Oregon.

Now the prices — $20 to $44 — may not get your attention at first. But take note that these numbers are for EIGHT pound jugs. Yep eight-pounders were all under $45! For example, H4895 was $44 for 8 pounds back in 1978, 45 years ago. And H335 was $20 for eight pounds — that’s just $2.50 per pound!

These days a single pound of a desirable powder such as Varget might cost $65 at some stores IF you can find it at all. On Hodgdon’s web site, H4895 powder is now priced at $68.99 per pound in July 2026. Using that current $68.99/lb figure, H4895 is now 12.5 times (1250%) higher than it was in 1978, when H4895 cost $44 for 8 pounds, i.e. $5.50 per pound.

Here are some comments from our Forum Members:

“Heck those prices are just about the same as current ones, just a little smaller container now.” — Joe

“I’ve got some H4831 in a can marked ‘WWII Surplus Powder’ with a price tag of $2.75. We’ll never see that again either.” Rick in Oregon

“1978 prices and [2024] income would be nice. Unfortunately that doesn’t work. If you compare prices and income, powder cost about the same. You also have to discount the temporary gouging that we are seeing.” — Tmwinds

“So I used to buy gas for 10 cents per gallon and they’d pump it, check the oil, and clean the windshield.” — Pirate Ammo

One comment suggests that the powder price hike actually tracks general U.S. currency inflation over the last four decades. So perhaps powder price increases are not as bad as they seem, when compared to how all prices have risen since 1978:

“Using H4895 [8 lbs.] as a comparison basis at $58.50 (list price) in 1978 calculates it to $276 in today’s money. Looking at … prices it looks like around [$380] for the same item in today’s money, so it really hasn’t gone up [that much as corrected for inflation]. Availability is another issue though and if someone is really needing powder they may well have to pay above suggested retail.” — Drover

How Cartridge Brass Is Made — Manufacturing Process Revealed

deep draw cartridge brass animated gif

Rifle cartridge brass manufacturingPrecision Benchrest and F-Class shooters favor premium brass from Lapua, Norma, Peterson, or RWS. (Lake City also makes quality brass in military calibers.) Premium brass delivers better accuracy, more consistent velocities, and longer life. Shooters understand the importance of good brass, but many of us have no idea how cartridge cases are actually made. Here’s how it’s done.

Top Deep-Draw Ram Illustration from Demsey Mfg.

The process starts with a brass disk stamped from strips of metal. Then, through a series of stages, the brass is extruded or drawn into a cylindrical shape. In the extrusion process the brass is squeezed through a die under tremendous pressure. This is repeated two or three times typically. In the more traditional “draw” process, the case is progressively stretched longer, in 3 to 5 stages, using a series of high-pressure rams forcing the brass into a form die. While extrusion may be more common today, RWS, which makes some of the most uniform brass in the world, still uses the draw process: “It starts with cup drawing after the bands have been punched out. RWS cases are drawn in three ‘stages’ and after each draw they are annealed, pickled, rinsed and subjected to further quality improvement measures. This achieves specific hardening of the brass cases and increases their resistance to extraordinary stresses.” FYI, Lapua also uses a traditional draw process to manufacture most of its cartridge brass (although Lapua employs some proprietary steps that are different from RWS’s methods).

RWS Brass Cartridge Draw process

After the cases are extruded or drawn to max length, the cases are trimmed and the neck/shoulder are formed. Then the extractor groove (on rimless cases) is formed or machined, and the primer pocket is created in the base. One way to form the primer pocket is to use a hardened steel plug called a “bunter”. In the photos below you see the stages for forming a 20mm cannon case (courtesy OldAmmo.com), along with bunters used for Lake City rifle brass. This illustrates the draw process (as opposed to extrusion). The process of draw-forming rifle brass is that same as for this 20mm shell, just on a smaller scale.

20mm cartridge brass forming

20mm Draw Set Oldammo.com

River Valley Ordnance explains: “When a case is being made, it is drawn to its final draw length, with the diameter being slightly smaller than needed. At this point in its life, the head of the draw is slightly rounded, and there are no provisions for a primer. So the final drawn cases are trimmed to length, then run into the head bunter. A punch, ground to the intended contours for the inside of the case, pushes the draw into a cylindrical die and holds it in place while another punch rams into the case from the other end, mashing the bottom flat. That secondary ram holds the headstamp bunter punch.


This video employs DEFORM-2D software to show the draw process for brass casings.

Lake City Brass bunterThe headstamp bunter punch has a protrusion on the end to make the primer pocket, and has raised lettering around the face to form the headstamp writing. This is, of course, all a mirror image of the finished case head. Small cases, such as 5.56×45, can be headed with a single strike. Larger cases, like 7.62×51 and 50 BMG, need to be struck once to form a dent for the primer pocket, then a second strike to finish the pocket, flatten the head, and imprint the writing. This second strike works the brass to harden it so it will support the pressure of firing.”

.300 Blackout Round in .223 Rem AR Upper — Instant Disaster

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56
Photos and Facebook post by Tactical Rifle Shooters

Yet another .300 Blackout disaster. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!

This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”

Image from Accurate Shooter Forum. Cutaway shows the jammed .30-Cal bullet:

For those who MUST have a .300 Blackout, here are some things you can do:

Comments by Folks Who Viewed these .300 Blackout Disaster Photos:

“The .300 Blackout is simply a badly-designed round. A properly-designed round would have had a feature in the shape that would have prevented cross loading in the first place.” — D. Santiago

“I almost made that mistake… I had a magazine of 300 BLK inserted in my .223/5.56 all night. Fortunately, I never pulled the trigger. Once I realized the mistake, I almost got ill. [After that incident] I no longer own a 300 BLK.” — B. Welch

“Happened to me hog hunting from a helo. Gun exploded in my face.” — B. Hood

“Fire-forming projectiles [is] so wrong in centerfire!” — M. Stres

“Had some dude come into the store the other day wanting .300 Blackout ammo to shoot in his 5.56 AR. It took 15 minutes of explaining for him to understand you got to have a .300 Blackout Upper!” — R. Williams

Case Concentricity and Bullet Run-0ut — What You Need to Know

Sinclair concentricity 101 eccentricity run-out reloading plans

Sinclair International reloading toolsSinclair International has released an interesting article about Case Concentricity* and bullet “run-out”. This instructional article by Bob Kohl explains the reasons brass can exhibit poor concentricity, and why high bullet run-out can be detrimental to accuracy.

Concentricity, Bullet Alignment, and Accuracy by Bob Kohl
The purpose of loading your own ammo is to minimize all the variables that can affect accuracy and can be controlled with proper and conscientious handloading. Concentricity and bullet run-out are important when you’re loading for accuracy. Ideally, it’s important to strive to make each round the same as the one before it and the one after it. It’s a simple issue of uniformity.

The reason shooters work with tools and gauges to measure and control concentricity is simple: to make sure the bullet starts down the bore consistently in line with the bore. If the case isn’t properly concentric and the bullet isn’t properly aligned down the center of the bore, the bullet will enter the rifling inconsistently. While the bore might force the bullet to align itself with the bore (but normally it doesn’t), the bullet may be damaged or overstressed in the process – if it even it corrects itself in transit. These are issues we strive to remedy by handloading, to maintain the best standard possible for accurate ammunition.

The term “concentricity” is derived from “concentric circle”. In simple terms it’s the issue of having the outside of the cartridge in a concentric circle around the center. That goes from case head and center of the flash hole, to the tip of the bullet.

Factors Affecting Concentricity

The point of using this term is to identify a series of issues that affect accurate ammunition. Ideally this would work best with a straight-walled case; but since most rifle cartridge cases are tapered, it equates to the smallest cross section that can be measured point by point to verify the concentric circle around the center. For the examples below, I’m working with .308 Winchester ammo.

The case walls have to be in perfect alignment with the center, or axis, of that case, even if it’s measured at a thousandth of an inch per segment (in a tapered case).

Figure 3: Case body in alignment with its axis, or centerline, even in a tapered case.

The case neck must also be in alignment with its axis. By not doing so you can have erratic bullet entry into the bore. The case neck wall itself should be as uniform as possible in alignment and in thickness (see the M80 7.62x51mm NATO cartridge in Figure 5) and brass can change its alignment and shape. It’s why we expand the case neck or while some folks ream the inside of the neck and then turn the outside for consistent thickness, which affects the tension on the bullet when seated.

Figure 5: Variations in case neck wall thickness, especially on some military brass, can cause an offset of the bullet in its alignment. This is an M80 ball round. Note the distinct difference of the neck walls.

Having a ball micrometer on hand helps, especially with military brass like 7.62x51mm in a semi-auto rifle, where there are limits as to how thin you want the neck walls to be. In the case of 7.62 ball brass you want to keep the wall to .0145″.

Figure 6: A ball micrometer like this RCBS tool (#100-010-268) can measure case neck thickness.

Turning the outside of the neck wall is important with .308 military cases regardless of whether you expand or ream the neck walls. There are several outside neck turning tools from Forster, Hornady, Sinclair, and others. I’ve been using classic Forster case trimming (#100-203-301) and neck turning (#749-012-890) tools for 40 years.

Bullet Run-Out
The cartridge, after being loaded, still needs to be in alignment with the center of the case axis. Figure 7 shows a bad example of this, a round of M80 ball. A tilted bullet is measured for what’s known as bullet “run-out”.

Figure 7: An M80 round with the bullet tilted and not aligned with the axis. This will be a flyer!

Run-out can be affected by several things: (1) improperly indexing your case while sizing, which includes not using the proper shell holder, especially while using a normal expander ball on the sizing die (it also can stretch the brass). (2) The head of a turret press can flex; and (3) improper or sloppy bullet seating. This is also relevant when it comes to using a progressive press when trying to load accuracy ammo.

Mid Tompkins came up with a simple solution for better bullet seating years ago. Seat your bullet half way into the case, back off the seater die and rotate the case 180 degrees before you finish seating the bullet. It cuts down on run-out problems, especially with military brass. You also want to gently ream the inside of the neck mouth to keep from having any brass mar the surface of the bullet jacket and make proper seating easier. A tilted bullet often means a flyer.

*Actually some folks would say that if we are talking about things being off-center or out-of-round, we are actually talking about “eccentricity”. But the tools we use are called “Concentricity Gauges” and Concentricity is the term most commonly used when discussing this subject.

Fire-Form with Fouler Shots — Save Time, Bullets, and Barrel Life

Fire-forming fouler barrel life fouling shots

Fire-Form with Foulers

PPC Fire-formingHere’s a tip for guys who shoot the 6 PPC, 6 Dasher, 6 BRA, .284 Shehane, or other wildcat cartridges that require fire-forming. Use your fouler shots to fire-form new cases. That way your fouler shots do “double-duty” and you get your brass fire-formed without putting extra rounds through your expensive barrel.

This procedure is recommended by Joel Kendrick, the 2004 IBS 600-yard Shooter of the Year. After he cleans his barrel, Joel knows it takes two or three shots to foul in the bore before accuracy returns. When shooting his PPC, Joel uses those fouler shots to fire-form his new brass. Joel explains: “I like to have relatively new brass always ready. By fire-forming a couple cases after each barrel-cleaning during a match, by the end of the weekend I’ve got a dozen or more freshly fire-formed cases to put into the rotation. If you do this with your fouler shots you get your fire-forming accomplished without using up any extra barrel life.”

This not only saves barrel wear, but it saves you trips to the range for the purpose of fire-forming. We thank Joel for this smart suggestion. For those who do not have a dedicated barrel for fire-forming, this should help keep your round-count down. Note: With this fouler fire-forming routine, you should ALWAYS do the fire-forming with the SAME POWDER you load for your match ammo. Joel currently works as the Supplier Quality Process Engineer for MMI-TruTec, a company that offers barrel surface coatings that can further extend your barrel life.
