How about a game of “Cartridge Chess”, with chess pieces sourced from your own ammunition collection? We think the concept of a Cartridge Chess Set is pretty clever, and it’s bound to be a conversation-starter at home or at the hunting lodge. With a little creativity, our readers could make their own Chess Sets like this, using a variety of cartridge types.
Create Your Own Cartridge Chess Set
This is a 3-D rendering originally found on the Cheaper Than Dirt Facebook page. We’d like to see a chess set with actual cartridges (assembled without powder or primers), perhaps with .32 ACP pawns and the 50 BMG and .338 LM as King and Queen.
Challenge: How many cartridge and shotshell types can you identify? The Pawns look like 9mm or 40sw pistol cartridges, while the Rooks (Castles) are obviously 12ga shotgun shells.
What’s Wrong with This Picture?: How many of you sharp-eyed chessmasters noticed a mistake in the placement of the “Royals” in the Cheaper Than Dirt 3-D rendering. Hint — look at the grid layout (top left) for the correct placement of Kings and Queens.
Many shooters prefer to deprime their brass before resizing. That way they can tumble cases or keep primer debris off their main press. To deprime cases before sizing or cleaning you can use a Decapping Die. This pushes out the spent primer without changing the neck or body of a case. Such decapping dies work fine, but they do require the use of a press. Here is a handy alternative — a cool tool that allows you to deprime brass anywhere — no press needed.
Handheld Primer Removal Tool From Frankford Arsenal
This cleverly-designed Hand Deprimer Tool allows you to deprime cartridge cases without a press. This hand-tool from Frankford Arsenal will deprime brass and capture primers conveniently. You can deprime your cases while watching TV or relaxing in your favorite chair.
This device lets you remove spent primers anywhere — no press needed and all the mess (cups/anvils/residue) stays in the capture chamber. This tool comes works with nearly all common case types up to .338 Lapua Magnum. With good leverage, this tool does the job quickly and efficiently. Forum members have praised this handy tool, but recommend wearing a thick glove if doing more than 100 cases in a session.
How to Adapt Tool for Small Flash Hole Brass
The Frankford Arsenal Deprimer Tool was designed for LARGE flash-hole brass. To deprime brass with small (1.5mm/0.59″) small flash-holes, as found on Lapua .220 Russian and 6mmBR cases, you will need to reduce the pin diameter. Frankford Arsenal currently recommends purchasing a replacement pin and “sanding it down” to the smaller diameter. NOTE: This is NOT difficult — simply spin the stock pin in some sandpaper.
This handy depriming tool is very versatile. With a universal, cylinder-style cartridge-holder, the tool can deprime a wide variety of cartridge types from .20 caliber up to .338 caliber. Three different plastic collets are provided to handle for different diameter cases. Spent primers are captured in a removable spent primer catch tube. Simply twist off the clear catch tube to dump the spent primers. With die-cast metal construction, this tool should last through many thousands of depriming cycles. MSRP is $65.99. Right now it is $47.99 on Amazon with 82% 5-star ratings.
Long-term User Review
One owner of this depriming tool has posted: “I have owned one of these for about eight years and deprimed over 10,000 cases with this tool. I have never had to replace a single part on it. You will have to adjust the return spring every so often, but that is a very easy task. If you are depriming a LOT of brass, the handle can tear up your hand a bit. Solution: Wear a Mechanics Glove. Easy Peasy! You will NOT regret this purchase.”
User Modifications — Grip Padding and High-Volume Capture
Many users recommended putting some kind of padding on the grip and front lever to reduce pressure on the fingers. This can be done with a wrap or a rubber covering. In addition, users have adapted the unit with an attached hose and large primer capture jug. If you depriming hundreds of cases at a time, this hose conversion may make sense.
Most of us own a .223 Rem rifle. Now, thanks to our friends at Rifleshooter.com we can assess exactly how velocity changes with barrel length for this popular cartridge.
Rifleshooter.com performed an interesting test, cutting the barrel of a .223 Rem rifle from 26″ all the way down to 16.5″. The cuts were made in one-inch intervals with a rotary saw. At each cut length, velocity was measured with a Magnetospeed chronograph. To make the test even more interesting, four different types of .223 Rem/5.56 ammo were chron’d at each barrel length. The Rifleshooter.com team that conducts these tests has a full-service gun shop, 782 Custom Gunworks — visit 782guns.com.
Test Barrel Lost 25.34 FPS Per Inch (.223 Rem Chambering)
How much velocity do you think was lost, on average, for each 1″ reduction in barrel length? The answer may surprise you. The average speed loss of the four types of .223/5.56 ammo, with a 9.5″ shortening of barrel length, was 240.75 fps total (from start to finish). That works out to an average loss of 25.34 fps per inch.

Rifleshooter.com observed: “Cutting the barrel from 26″ to 16.5″ resulted in a velocity reduction of 214 ft/sec with the UMC 223 55-grain cartridge, 244 ft/sec with the Federal M-193 cartridge, 288 ft/sec with the Winchester M855 cartridge and 217 ft/sec with the Back Hills 223 68-grain match cartridge.”
How the Test Was Done
The testers described their procedure as follows: “Ballistic data was gathered using a Magnetospeed barrel-mounted ballistic chronograph. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Average velocity and standard deviation were logged for each round. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. The barrel was cut off using a cold saw. The test protocol was repeated for the next length. Temperature was 45.7° F.”
See More Barrel Cut-Down Tests on Rifleshooter.com
Rifleshooter.com has performed barrel cut-down tests for many other calibers/chamberings including 6mm Creedmoor, .308 Winchester, and .338 Lapua Magnum. See these test results at Rifleshooter.com.
Much Different Results with 6mmBR and a Longer Barrel
The results from Rifleshooter.com’s .223/5.56 test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. When we cut our 6mmBR barrel down from 33″ to 28″ we only lost about 8 FPS per inch. Obviously this is a different cartridge type, but also our 6mmBR barrel end length was longer than Rifleshooter.com’s .223 Rem start length. Velocity loss may be more extreme with shorter barrel lengths. And, of course, different cartridge types and powder/bullet combinations will yield different results.
If you load pistol ammo you should have a case gauge (aka “gage”) for each cartridge type you reload. Caliber-specific, precision-machined cylindrical gauges perform many important functions. They will instantly reveal if your rounds are too long or have excessive headspace. They will also show if your case is bulged or otherwise too fat to chamber easily. You can use the gauge with sized brass as well as loaded rounds.
Case gauges are a “must-have” for anyone loading handgun ammunition, particularly if you crank out large quantities of pistol ammo with a progressive press. An oversize round can cause a misfeed, jam, or other problem. That can ruin your day if you are in the middle of a shooting match. If you are relying on your handgun for self-defense, the last thing you want is a malfunction of any kind. This Editor personally runs every pistol round through a gauge before it goes into the ammo box.
UltimateReloader.com Video Shows How to Use Pistol Case Gauges:
Our friend Gavin Gear of UltimateReloader.com has prepared an excellent video that explains the benefits of pistol case gauges and shows how to use them. Gavin uses the quality gages produced by L.E. Wilson. These are available for the most popular handgun cartridges, both autoloader cartridges, and rimmed revolver cartridges. Gavin demonstrates gage use with .40 SW and .44 magnum cases.
Gavin states: “Using a case gage is very simple, and I would recommend that you add one of these gages to your reloader’s tool chest for each of the pistol cartridge types you reload. It may just save you a lot of time and hassle. Peace of mind is hard to put a price on!”
Even with high-quality brass from Lapua, Peterson, Norma, Alpha and RWS, occasionally you may find one or two cases per box which have a small flake or obstruction in the flash-hole. This will appear like a thin crescent on one side of the flash hole (see photo). You should inspect ALL new brass before loading to identify any pieces with a partially-obstructed flash hole. It’s a good idea to remove any flake or thin crescent left as an artifact of the flash-hole forming process. Because the flash-hole itself is normally centered and of the correct diameter, it is not necessary to ream the flash-hole to a larger diameter. All you really need to do is remove the small obstruction(s). This can be done quickly with inexpensive tools.
Use a Small Pin Vise to Remove Flash-Hole Obstructions
Folks have asked if there is a tool that can remove obstructions from a Lapua small, BR-sized flash hole without opening the hole size. The Lapua PPC/BR flash hole is spec’d at 1.5mm, which works out to 0.059055″. Most of the PPC/BR flash-hole uniforming tools on the market use a 1/16″ bit which is nominally 0.0625″, but these often run oversize — up to 0.066″.
If you want to just clear out any obstructions in the flash hole, without increasing the flash hole diameter, you can use an inexpensive “pin vise” with an appropriate drill bit. For $5.39, Amazon sells a 10-piece set of cobalt steel 1.5mm drill bits, that matches the Lapua flash hole exactly. Other vendors offer a #53 pin vise drill bit that measures .0595″ or .060″ (depending or source). An 0.0595″ bit is close enough. You can find pin vises and these small-diameter drill bits at hobby stores.
For quite some time, Sinclair Int’l has sold a similar device for small (PPC and BR-size) flash holes. Like the 07-3081 unit for large flash holes, the 073000 Reamer for small flash holes works from the outside, so it can index off the primer pocket. It reams to .0625″, and also costs $29.99. The standard dimension for Lapua 220 Russian and 6mmBR flash holes is 1.5mm or .0590″. This tool will permit standard-size decapping rods with .0625″ tips to work without binding. However, note that both Forster and Redding normally supply .057″ decapping pins with their PPC and BR dies. So, it is NOT necessary to ream your Lapua BR/PPC flashholes, unless you prefer to do so for uniformity. It IS, however, a good idea to check BR/PPC flash holes for burrs before loading the first time.
NOTE: If you purchase either the 073081 or 073000 Sinclair Flash Hole Reamer tools, we recommend you mic the cutter tip before you process a bunch of cases. Sometimes a tip comes through that is oversize. This will ream the flash holes larger than you may intend.
We are well into spring 2026. That means folks will be getting ready for varmint safaris into prairie dog country. Todays’ story may help you choose a cartridge for your next varmint rifle. This Sunday we feature a Cooper chambered for the .204 Ruger — an impressive cartridge with way more speed that a .223 Rem, plus a flatter trajectory.
For many years, Ken Lunde journeyed to South Dakota to visit with his father, and do a little varmint hunting. This article features Ken’s Cooper Model 21 Montana Varminter chambered in .204 Ruger. During past varminting holidays in South Dakota, Ken had a chance to try the speedy .204 against his “old reliable” .223. He came to favor the .204 for its accuracy, flat trajectory, and superior performance in the wind. Ken told us: “I love my .223, but the .204 has the edge for Dog-Town duty.”
The Cooper Montana Varminter in .204 Ruger
Story and photos by Ken Lunde
I’ve been a big fan of Cooper Arms rifles ever since my dad introduced them to me a few years ago. I prefer Cooper Arms rifles over others because they perform as they should out-of-the-box, and have outstanding workmanship and beauty. You get form and function. You don’t need to choose one over the other. For the price one pays, Cooper Arms rifles are a great bargain. I mount a quality scope, usually a higher-end Leupold with a 40mm objective, go through barrel break-in, and they always perform extraordinarily well. I should state that all of my rifle shooting is geared towards hunting. In other words, any shooting I do on paper is treated as preparation for using the same rifle for hunting, whether it’s for varmints such as prairie dogs, or for larger game.
Cooper Varmint Rifles–Components and Variations
The featured rifle is a Cooper Arms M21 Montana Varminter (aka “MTV”) chambered in .204 Ruger. It has a 24″ varmint-taper stainless steel barrel with a 1 in 12-inch twist. This twist rate seems to be typical of .204 Ruger barrels from other manufacturers. The stock is AA+ grade Claro Walnut, and has the varmint fore-end, “Buick” vents, and steel grip cap that are standard on the Montana Varminter configuration. Among Cooper’s three wood-stocked varmint rifle configurations — Varminter, Montana Varminter, and Varmint Extreme — I prefer the Montana Varminter as it seems to be the best balance of value versus features. Plus, I like the “Buick” vents. They’re very pleasing, at least to my eyes. Maybe that’s why I own seven of them, in M21 and M22 actions, and in a variety of calibers. [Editor: Ken’s father has a near-identical .204 Ruger Cooper, with consecutive serial number.]
For this rifle, I decided to mount a Leupold VX-III 6.5-20×40 LR scope with the Varmint Hunter reticle. The rifle came with Leupold STD bases in Matte finish, and I used Leupold 30mm STD rings in Medium height and Matte finish. I took the time to align the bottom rings on the bases, and properly lapped them. Other than mounting the scope, no custom work was done, because none was necessary. The trigger is superb out-of-the-box, which is typical of Cooper rifles.
Load Development and Accuracy I first tried factory ammo, loaded with Hornady 32gr and 40gr V-Max. The 32gr load shot the best — five-shot groups were slightly larger than a half-inch at 100 yards. My dad heard that Alliant Reloder 10X was a good powder for this cartridge, and he worked up a load using the Sierra 32gr BlitzKing bullet. He found that 26.5 grains was the right amount for his rifle. Considering that my rifle was probably made on the same day, having a consecutive serial number, I decided to try my Dad’s load, along with a half-grain up and down: 26, 26.5, and 27 grains of powder. I, too, found that my rifle prefers 26.5 grains of RL 10X. With this load, I could shoot consistent quarter-inch, five-shot groups at 100 yards. Cartridge OAL is 2.353″, or 1.990″ measured from the ogive.
I am using Winchester brass, Federal 205M primers, Alliant Reloder 10X powder, and Sierra 32gr BlitzKing bullets. I use Forster dies, and load with a Forster Co-Axial single-stage press. Here are two typical targets. As you can see, this .204 can shoot.
WARNING: Current lots of Reloder 10X powder may be somewhat different. 26.5 grains of RL 10X may be TOO HOT for your rifle and 32gr bullets. Seating depth, throat length, and COAL will affect pressures dramatically. START LOW at 24.5 grains and work up.
Cartridge Smack-Down — .204 Ruger vs. .223 Remington
Ken made these comments when he first tested his .204 Ruger vs. his trusty (and very accurate) .223 Remington: “I brought along two rifles. The first was my ‘proven’ varmint rifle, the one chambered in .223 Rem. It has stunning wood, and clearly escaped the factory with AAA grade Claro Walnut. That rifle also shoots consistent five-shot, quarter-inch groups at 100 yards. For the .223, my preferred load uses Winchester brass, Federal 205M primers, Hornady 40gr V-Max bullets (non-moly), and 26.2gr of Vihtavuori N133 powder.
I found that I very much enjoyed shooting the .204 Ruger rifle, which explains why I used only the .204 Ruger during the second trip, although I also brought along the .223. Why did I favor the .204? Well, those little 32gr bullets really zing out of the barrel, with a very flat trajectory, like a .22-250. And, to my surprise, they buck the wind very well, perhaps even better than .223. While I am no ballistics expert, I think that this may be due to its high velocity, clearly over 4,000 fps.
Related to the flat-shooting characteristics of the .204 Ruger cartridge, I found that I was able to depend on my Leupold’s Varmint Hunter reticle for both bullet drop and wind compensation. It was a very pleasing experience. For determining ranges in the field, I used a new set of optics for this trip, Leica’s new Geovid 8×42 BRF range finder.

Dakota Dog-Town Adventures with Dad
Editor: When this story was originally written, Ken Lunde made two summer trips to South Dakota to hunt prairie dogs with his father. Here is his account of those summer-time adventures.
I drove to South Dakota twice [that year]. For the first trip, I brought two Coopers, both M21 MTVs, in .223 and .204 Ruger. My .223 Cooper was already proven during previous trips to South Dakota. I fired a total of 300 rounds, 200 from the .204 Ruger and 100 from the .223. I found the .204 Ruger to be flatter-shooting than .223, and it also seemed to buck the wind better, even with the light 32gr bullets.
For the second trip, I ended up shooting 301 rounds, all from the .204 Ruger rifle. I had discovered the importance of accuracy when hunting prairie dogs — and the .204 Ruger had exceptional accuracy. There are many variables with which to contend while shooting: wind speed, wind direction, variable distance to target, bullet drop, steadiness, and the accuracy of the load in the rifle. I find that the more of these variables I can control or compensate for, the greater the success.
I estimate I bagged about 250 prairie dogs during each trip, meaning about 500 in total for this season. There were misses, of course, but those are generally 400 yards and beyond, when wind becomes too much of a factor, or shooter error. And, for each trip, I managed to get two or three “doubles,” which is lingo that means that a single bullet results in two dead prairie dogs. Prairie dogs tend to congregate, and when they do, “doubles” become possible, and “triples” are not out of the question. One of these “doubles” was clearly visible through my scope.
The best part of these trips is spending quality time with my dad, doing something that both of enjoy: shooting and hunting. I grew up in Wisconsin, and my parents moved to South Dakota in December of 2004. South Dakota, and sometimes Wyoming, have come to be our preferred hunting states, because they’re superb hunting destinations. It is great that my parents have decided to settle in one of those states. In fact, the drive from California is not bad. It takes a little over one day. I also brought my teenage son along. He enjoyed the chance to go fishin’ with Grand-Dad, and one day “teen-angler” managed to catch us six fine trout.
My first trip to South Dakota, at the end of June, offered a unique oppor-tunity, since First Stop Guns was having a show that coincided with my time in the area. Dan Cooper, founder and owner of Cooper Arms, was present at the show. My dad and I decided to host a small dinner at my parents’ new home, and we invited Dan Cooper and others. I brought tenderloin steaks from California for this. In addition to Dan Cooper, Mark and Steve Blote of First Stop Guns, along with Paulette Kok of Dakota Arms, attended the dinner. It was a pleasure and honor to be in their company. They’re all very personable.
My father has a rather vast collection of Cooper Arms rifles, so I naturally invited Dan Cooper to check them out. A couple of them turned out to be special. One turned out to be the very first .22-250 rifle that Cooper Arms built. It is a Model 22 Varmint Extreme with ebony fore-end tip. Another is an Model 21 Classic with Schnabel fore-end, and according to Dan, less than 30 such rifles were ever crafted. It’s in the rack picture at left. Two of Dad’s rimfires are also very early Coopers, with two-digit serial numbers. They were made before Cooper started using the magazine insert supplied by Anschütz. And check out the middle rifle in the rack. It’s a Dakota Arms Model 97 Deluxe Hunter that I bought for Dad. He hand-picked the amazing wood blank, and it turned into an outstanding rifle stock. You can see how it stands out in the photo. Interestingly, the day before our dinner, I used Dad’s M21 with the Schnabel stock, chambered in .222, to hunt prairie dogs in the 9,000 acres of public hunting land bordering the eastern side of my Dad’s 56-acre “recreational” property, situated just north of Hot Springs, SD. Here’s a photo. Yes, I’d say this is a great place to hunt and “get away from it all”.
Spring Groundhog Hunting — Fun and Challenging
Springtime is the right time for groundhog hunting in the Northeast USA. Groundhog hunting is both fun and challenging. In today’s Saturday Showcase, we feature three videos showing successful groundhog hunts. Then there is a video about checking your equipment and verifying your varmint rifle zero.
We’ve even included a good video offering cooking tips for groundhog/woodchuck.* Yes groundhog meat can be quite savory — used in stews, sandwiches, or tacos. Last but not least we’ve included a section on groundhog shooting matches. These are fun matches with paper and/or steel groundhog targets.
Groundhog Hunt Report — Successful Stalk and Shoot
Here’s a great Realtree.com video showing successful groundhog hunts. This covers the process of spotting and tracking groundhogs on farmlands. Woodchucks are sensitive creatures that get easily spooked. This video shows that groundhog hunters need patience and skill, plus an accurate rifle.
Groundhog Hunting on the Family Farm with .17 HMR
In this video, the host employs his CZ 457 rifle chambered in .17 HMR to hunt groundhogs on his farm. The video provides a hunter’s POV with excellent Scope-Cam footage. This young shooter has 280 videos on his popular Blocketh Outdoors Channel including videos showing how to stalk groundhogs successfully. These critters go to ground quickly if they see or hear the hunter. NOTE: The lead photo for this Saturday Showcase comes from another Blocketh Outdoors groundhog video.
Groundhog Killshot Compilation Video
Here’s a classic “killshot” video showing multiple hits on groundhogs. If you want to see how a well-aimed varmint bullet can flip, spin, and elevate a groundhog, this video will keep you entertained. While we like explosive hits on prairie dogs, it may be better to use a solid, non-expanding bullet if you plan to harvest the groundhog (aka woodchuck) meat.
Groundhog Hunting — Importance of Confirming Your Zero
This AR15 Hunter channel video covers getting ready for spring groundhog season. This is a helpful video that shows how to confirm your zero on your varmint rifle. If you have an AR-platform Modern Sporting Rifle, this video is worth watching.
If you don’t have groundhogs in your part of the USA, don’t fret. You can still have fun hunting smaller varmints such as ground squirrels and Prairie Dogs. Here’s a good video covering P-dog hunts with a suppressed .223 Rem AR. The video covers recommended equipment including bipod, tripod, and optics.
Groundhog Matches — Fun Shooting at Paper and Steel ‘Hogs
Along with actual groundhog hunting, many shooters like to shoot paper and/or steel groundhogs in club groundhog competitions. These are fun matches that you can shoot with a variety of rifles. Our first choice would be a 22 BR for ranges out to 450 yards or a 6 BRA if targets are farther out. One popular match in the Northeast is the St. Thomas Ground hog shoot in Pennsylvania (see below).
At clubs across the country, varmint fun shoots (also known as “groundhog matches”) are becoming more popular every year. In these matches, usually shot from the bench, you engage paper targets, clay pigeons, steel “critter” silhouettes, or some combination of paper and reactive targets. Shooters like these matches because you can shoot a wide variety of rifles, you don’t have to spend a fortune to be competitive, and there is fun for the whole family. Rules are inclusive — you won’t be turned away because your rifle is two ounces overweight. A large percentage of the match fees usually go back to shooters in the form of cash prizes. And the level of camaraderie is high.
St. Thomas Groundhog Shoot, Report by Jonathan Trivette
Nestled at the base of a mountain in south-central Pennsylvania is the St. Thomas Sportsmen’s Association. On a cool Saturday morning you’ll find some of the area’s best shooters at the monthly Groundhog Match. The match attracts shooters from Virginia, Maryland, West Virginia, and of course Pennsylvania.
It may not be the longest-yardage match in the area, but it can be the one of the toughest. The range is sloped up the mountain a little so the winds can be very tricky. Often times the three wind flags at 200, 300, and 400 yards will all be blowing in different directions.
* “Groundhog” and “Woodchuck” are simply two different names for the same animal. Both terms have been used in the English language since the 1600s. In many places, the terms are used interchangeably, but “groundhog” is now increasingly more common in the USA.
Lapua and Berger, two leading companies with great products for competitive shooters and skilled hunters, will have multiple new and enhanced products on display at the 2026 NRA Annual Meetings & Exhibits in Houston, Texas, April 16-19, 2026. Lapua will showcase its new MaxRange Target Bullets and TRX polymer-tipped solid copper bullets and ammunition designed for long-range precision shooters and hunters. And Berger will display a variety of new bullets and hunting ammunition offerings.
New Lapua Products for 2026
New MaxRange™ Target Bullets

Berger — New Products for 2026
Berger will showcase new precision bullets and ammunition at the 155th NRA Annual Meetings & Exhibits in Houston, TX this week. New offerings include 7mm PRC Elite Hunter ammunition, .22 caliber 69gr OTM bullets, 300 PRC 217 Grain Elite Hunter ammunition, and 1500-count Competition Packs designed for long-range accuracy and competition shooting.
New Berger Competition Bullet Packs
This year Berger will sell 1500‑count Competition bullet packs. This allows handloaders to secure large quantities of bullets from the same production lot. That helps assure load accuracy and consistency when loading hundreds of rounds for many matches. This helps PRS, Fullbore, F‑Class, NRL Hunter, ELR, and other disciplines maintain consistent accuracy at 1,000 yards and beyond. The following Competition Packs are available now at authorized Berger retailers:
6mm 105gr Hybrid Target
6mm 109gr Long Range Hybrid Target
.25 caliber 135gr Long Range Hybrid Target
6.5mm 140gr Hybrid Target
6.5mm 144gr Long Range Hybrid Target
7mm 180gr Hybrid Target
7mm 184gr F-Open Target
.30 caliber 200.20X Hybrid Target
New .22 caliber 69 Grain OTM Bullets and .223 Rem OTM Ammunition
Berger is releading new 69gr OTM bullets. These are optimized for AR-style rifles with a 1:9″ (or faster) twist used in 200- and 300-yard competition. Berger also introduces .223 Remington 69gr OTM ammunition, loaded with premium components, including Vihtavuori powder. This new OTM ammo should deliver great precision and reliability.
New 7mm PRC Elite Hunter Ammunition
Berger introduces new 7mm PRC Elite Hunter loads featuring heavy-for-caliber options that deliver exceptional external ballistics and long-range terminal performance. Available in 175-grain and 195-grain Elite Hunter offerings, both loads are optimized for modern, fast-twist rifles.
New 300 PRC 217 Grain Elite Hunter Ammunition
Berger’s new 217gr Elite Hunter 300 PRC ammunition offers a heavy-for-caliber solution that maximizes energy and terminal performance. Featuring an ultra-high 0.695 BC and increased sectional density, this ammunition delivers outstanding downrange accuracy and impact energy.
Is factory 6.5 Creedmoor ammunition good enough to win a PRS or NRL competition? The answer is a resounding “YES” if we’re talking about Berger ammunition. Produced with Berger match bullets and premium Lapua brass, this Berger 6.5 Creedmoor ammunition demonstrated excellent accuracy, impressive velocity, and very good ES/SD numbers. When tested at 1000 yards with an MPA-stocked PRS rig with Rem 700 action, this ammo showed just half-MOA of vertical, and produced a group that would have been a 50-1X in F-Class competition. That’s quite impressive for a PRS rig.
This ammo test was performed by our friend Erik Cortina from Texas. The reigning SW Nationals F-Open champion, Erik is a top F-Class competitor who also shoots tactical matches (for fun and glory). A couple seasons back, Erik built a new 6.5 Creedmoor with a Remington 700 action. Though this rifle sports a top-shelf MPA chassis and premium Kahles scope, Erik calls this his “budget build” because it has a plain Rem 700 factory action rather than the elite Borden actions he normally runs. Erik’s actions of choice are the Borden Mountaineer for PRS and Borden BRM-XD for F-Class.
Erik posted: “Shot my budget 6.5 Creedmoor … with Berger Bullets factory ammo. I shot five rounds over the chrono to get speed. I used BC info from the box and it all lined up properly. I adjusted my ECTuner to tune load and it took just 15 shots to get it shooting well. It’s simple with good components.”
This Berger factory ammo features Berger 130gr Hybrid OTM Tactical bullets. The Lapua 6.5 Creedmoor cases have a large rifle primer. You can see this ammo displays good velocity with Extreme Spread and Standard Deviation rivaling good hand-loads.
Cortina says the very accurate Brux barrel and razor-sharp 6-24x56mm Kahles scope help achieve this kind of outstanding performance at 1000 yards. Here are the key components for Erik’s latest PRS rig:
Barrel Tuner by Erik Cortina — Fits Behind Muzzle Brake
This rifle features a barrel tuner designed and crafted by Erik Cortina. You can the EC Barrel Tuner alone, or, as you can see, the EC Tuner can be fitted BEHIND a muzzle brake. Erik tells us: “The EC Tuner allowed me to tune the barrel to my ammo rather than tuning the ammo for barrel as is done when reloading. With the tuner, there is no need to try different brands of ammo as they can all be tuned to shoot as good as possible in my rifle.”
Vihtavuori offers an updated, user-friendly reloading data center on its website. This data page works well with all formats — smartphones, tablets, and desktop computers. On this page you can find recommended loads for 80+ cartridge types all in one place. You don’t have to click through multiple web pages. 
How about a game of “Cartridge Chess”, with chess pieces sourced from your own ammunition collection? We think the concept of a Cartridge Chess Set is pretty clever, and it’s bound to be a conversation-starter at home or at the hunting lodge. With a little creativity, our readers could make their own Chess Sets like this, using a variety of cartridge types.
I first tried factory ammo, loaded with Hornady 32gr and 40gr V-Max. The 32gr load shot the best — five-shot groups were slightly larger than a half-inch at 100 yards. My dad heard that Alliant Reloder 10X was a good powder for this cartridge, and he worked up a load using the Sierra 32gr BlitzKing bullet. He found that 26.5 grains was the right amount for his rifle. Considering that my rifle was probably made on the same day, having a consecutive serial number, I decided to try my Dad’s load, along with a half-grain up and down: 26, 26.5, and 27 grains of powder. I, too, found that my rifle prefers 26.5 grains of RL 10X. With this load, I could shoot consistent quarter-inch, five-shot groups at 100 yards. Cartridge OAL is 2.353″, or 1.990″ measured from the ogive.
I estimate I bagged about 250 prairie dogs during each trip, meaning about 500 in total for this season. There were misses, of course, but those are generally 400 yards and beyond, when wind becomes too much of a factor, or shooter error. And, for each trip, I managed to get two or three “doubles,” which is lingo that means that a single bullet results in two dead prairie dogs. Prairie dogs tend to congregate, and when they do, “doubles” become possible, and “triples” are not out of the question. One of these “doubles” was clearly visible through my scope.
My first trip to South Dakota, at the end of June, offered a unique oppor-tunity, since First Stop Guns was having a show that coincided with my time in the area. Dan Cooper, founder and owner of Cooper Arms, was present at the show. My dad and I decided to host a small dinner at my parents’ new home, and we invited Dan Cooper and others. I brought tenderloin steaks from California for this. In addition to Dan Cooper, Mark and Steve Blote of First Stop Guns, along with Paulette Kok of Dakota Arms, attended the dinner. It was a pleasure and honor to be in their company. They’re all very personable.
Spring Groundhog Hunting — Fun and Challenging
Along with actual groundhog hunting, many shooters like to shoot paper and/or steel groundhogs in club groundhog competitions. These are fun matches that you can shoot with a variety of rifles. Our first choice would be a 22 BR for ranges out to 450 yards or a 6 BRA if targets are farther out. One popular match in the Northeast is the St. Thomas Ground hog shoot in Pennsylvania (see below).
Cortina says the very accurate Brux barrel and razor-sharp 6-24x56mm Kahles scope help achieve this kind of outstanding performance at 1000 yards. Here are the key components for Erik’s latest PRS rig:
