While many of our readers are caught in the wicked cold-spell hitting the North Central states, take heart — spring is right around the corner. That means folks will be getting ready for varmint safaris. Here’s a story that may help you choose a cartridge for your next varmint rifle.
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.”
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, meaning 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’ve been able to 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.
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.”
Here are highlights from an article Glen Zediker wrote for the Midsouth Blog. In this article Glen focuses on cartridge brass for semi-auto rifles, AR-platform guns in particular. Glen notes that semi-autos are tougher on brass than bolt-action rifles, so you need strong, durable brass, that has been full-length sized. And you need to be careful about neck tension, and primers. The article starts with Glen’s recommendations for tough, hard brass, and then includes the points outlined below.
ONE: Full Length-Size Cases with Adequate Shoulder Set-Back
This is a huge source of debate… amongst my readers, but, since now I’m strictly speaking of semi-auto needs I doubt there will be much dissent: full-length resize all cases! Most cases from most semi-autos will emerge with a pretty well-blown case shoulder [taming down an excessively functioning gas system can reduce this]. Make double-sure you’re sizing the cases down to at least 0.003 clearance. If you don’t there are safety and function problems ahead.
TWO: USE Sufficient Neck Tension
The case neck [must be] reduced an adequate amount to retain the bullet. There should be a minimum net difference of 0.003 inches (three-thousandths) between sized outside case neck diameter and loaded round outside case neck diameter. [Editor — that means at least three thou of “grip”.] Reason: don’t take a chance of inadvertent bullet movement during the recoil and feeding cycles. That movement can be back or forward! It’s easily possible for a bullet to jump ahead when the inertia from the bolt carrier assembly chambers the next round.
THREE: Use Tough Primers
Choose a tough primer! There’s a floating firing pin on an AR15 (M1A also) that is supposed to be held in check but that system doesn’t always work! If you load and extract a round and see a little dimple in the primer, that’s from the firing pin tapping off of it (again, created by inertia of bolt closing). A combination of a high primer and a sensitive primer cup assembly can create a “slam-fire”. Brands? CCI has some mil-spec primers that work well, and I’ve had great success with Remington 7-1/2. Some of the well-respected “match” primers are a little thin. The CCI and Remington also hold up well to the (sometimes) greater firing forces working on the primer (again, from the quick unlocking).
And, finally, make double-sure that each and every primer is seated to below flush with the case head! That’s true for any firearm (because it also means that the primer is fully seated) but imperative for safety in a semi-auto. This is especially an issue for those who use a progressive-type loading press.
The NRA Great American Outdoor Show is underway right now in Harrisburg, Pennsylvania, continuing through Sunday, February 10. To promote the show the NRA is using social media. Here are some interesting Twitter Tweets about the Show from various NRA sources.
NRA Museum — The Barrett 50. Museum staffs says: “We wanted to bring out the ‘big guns’ for our Harrisburg traveling exhibit this year. Not much desert around Harrisburg, but if we run into snow this week, this Barrett can easily handle any extremes in temperature!”
NRA Museum – Gyrojet Pistol. The NRA Museum took two rare Gyrojet “rocket ball” guns up to Harrisburg, PA for the traveling exhibit. Below is the first, an experimental Mark I model. This does not use a conventional case, powder, and primer. Rather the projectile streams hot gases like a miniature rocket.
Watch Slow-Motion video of the Gyrojet Mark I shooting rocket-propelled projectile:
NRA Museum — Colt Model 1851 Navy Revolver with Canteen Shoulder Stock. This circa 1857 percussion Colt features an innovation that then-Secretary of War Jefferson Davis had decided that his friend Sam Colt could produce. Gift of the Thurston Collection.
From Shooting Illustrated — Pack Rifles. Trekking into the woods? Make sure you’re prepared with one of today’s easily carried survival and self-defense packages. Shown is a side-folding AR15 variant plus a Henry AR-7 Survival Rifle, which stows action and barrel inside the buttstock. FULL Story Here.
The Berger SW Nationals is coming up in a couple weeks. At that match, the sling shooters and F-Class competitors need to haul lots of gear from parking lot to the firing line, and then move from yardage to yardage. Along with their rifles, shooters need to bring mats, front rests or bipods, spotting scopes (with stands), rear bags, ammo boxes, log sheets, tool kits, and heavy coats (for the sling shooters).
To do the hauling, you can certainly purchase a factory-made, purpose-built cart that folds up and has all the bells and whistles. The Creedmoor Sports CRC-1 (photo right) is a proven, quality product that works great. You’ll find these used by top shooters at Camp Perry. But the Creedmoor CRC-1 cart costs $499.95. For a fraction of that price ($55.99), plus a few dollars more for do-it-yourself enhancements, you can have a heavy-duty cart that will haul all your gear just fine, though it doesn’t fold up. In the top photo is a Harbor Freight Welding Cart we saw at the Berger Southwest Nationals. This rig is carrying a rifle in hard gun case, bipod, folding chair, shooting mat, tripod, spotting scope, rear sand-bag, and ammo box — that’s a lot of gear!
Check out the Harbor Freight Welding Cart, item #65939. This cart is ON SALE right now for just $59.99. Overall size is 29-1/2″ L x 20″ W x 49″ H, and width between side rails is 18″. The wheels (with tires) are 20 3/4″ in diameter for smooth rolling. Consider that, if you made your own cart from scratch you could easily pay $30.00 or more just for the large-diameter wheels and axle. Do note — this cart has air-filled tires. Be sure to inflate before you go to the Range!
This Cart is now on sale for just $55.99 — GREAT DEAL!
As sold, the Harbor Freight Welding Cart can benefit from upgrades for range use. But with a few bungee cords (and some creativity), the cart can be adapted pretty easily to hauling your gun gear. If you want to enhance the basic cart, it’s easy to add plastic side-panels on the bottom unit, and fit a barrel-holding system on the cross-tube. This ensures rifles and gear won’t flop forward. (A small piece of wood under the bottom panel provides a bit of extra lift that will keep the bottom plate out of the dirt and gravel.)
SHOT Show is the largest gun/hunting trade show in the world, with tens of thousands of products and accessories on display. For a gun guy, going to SHOT Show is like being a kid in a candy store.
We’ve seen that the SHOT Show 2019 videos we’ve showcased thus far have been very popular with our readers. So today we are bringing you five more SHOT Show videos, featuring products from Accuracy International, Proof Research, Savage, Thompson Center (T/C), and five pistol-makers.
Proof Research — Hi-Tech Barrels and Rifles
Here our friend Gavin Gear of UltimateReloader.com learns about the carbon-wrapped Proof Research barrels. Being lighter than conventional barrels, these Proof Research barrels definitely offer an advantage for hunters packing into the wild.
The Proof Research carbon barrels have also performed very well in PRS/NRL tactical competitions. There is a lot of technical information shared in this interview, so it is definitely worth watching.
Thompson Center Arms (T/C) — Value Leader
Thompson Center Arms (T/C), a Smith & Wesson Company, is known for value-priced rifles that offer great “bang for the buck”. We’ve regularly featured T/C rifles in our Deals of the Week. There are some impressive guns in the T/C line-up, including the T/C LRR (Long Range Rifle).
With an $1100 street price, this rig is a great value choice for PRS factory class. The rig balances well and we like the thumbwheel adjustments for LOP and cheek height.
Accuracy International $19.5K ASR with 3-Barrel Deployment Kit
If T/C guns are bargains, then the Accuracy International (AI) line of rifles is at the other end of the spectrum. At SHOT Show this year AI displayed its Advanced Sniper Rifle (ASR) which will be submitted for SOCOM’s multi-caliber rifle program. This rig costs a hefty $19,544.00 as a “deployment kit” including three barrels (.308 Win, .300 Norma Mag, and .338 Norma Mag), two bolt bodies, key spare parts, magazines and a MilSpec transport case.
The AI ASR employs a QuickLoc barrel change system for rapid caliber swaps. The rifle features a new two-position, AR-type safety and redesigned 2.5-lb trigger. The fore-end tube includes an RRS™-compatible rail, integrated top rail, and M-Lok™ mounting interface.
Savage Hunting Rifles — Model 110 High Country
For 2019 Savage unveiled some handsome, versatile rifles for backcountry hunters. These rigs feature nice camo finishes, adjustable AccuFit cheekpieces and buttpads, and barrels threaded at the muzzle for brakes or suppressors.
We liked these new rifles, particularly the Model 110 High Country featured above. It has a tough corrosion-resistant finish and spiral-fluted barrel for weight savings.
Handguns — Some of the Best New Pistols for 2019
In this video, The Firearm Blog (TFB) presents its five favorite new-for-2019 handguns. TFB praised the new KelTec CP33, a VERY impressive new .22 LR rimfire target pistol, boasting a 33-round clear magazine. On Media Day, we shot the CP33 with a suppressor and were extremely impressed. The gun balances well, and the trigger is EXCELLENT — really surprisingly good. Glock attracted attention with the new Glock 43X and 48 silver-slide models. The 43X does offer more capacity (10 rounds) with a longer grip vs. the Glock 43. Buyers may be attracted by the silver PVD-finished slide. Frankly, that’s nothing more than cosmetics and the Glock still retains not-so-great ergonomics and a mediocre trigger. There are better striker-fired, DAO polymer-framed pistols out there, for less money.
New KelTec CP33 is a high-capacity winner, with a great trigger.
Splatterburst 1″ circles, 62 per sheet, 10-pk $8.99. These can be pasted on other paper backers.
We’ve all seen conventional splatter targets with a single large black bullseye. When a shot hits the target, a halo (usually neon yellow) appears around the bullet hole. This makes it easier to see your shot placements indoors, or at long range outdoors. Today we feature a variety of other targets that also offer the cool halo/splatter effect. We’ve found grids, multiple bull targets, sheets with 62 one-inch circle pasters, handgun training targets, and even white background splatter targets (that produce black halos). Try out some of these targets for fun (kids love plinking with splatter targets).

This week we return to our 6mmBR.com roots with an article on David Bergen’s slick 24″ Drop-Port Viper. This was one of the first 6BR rifles we featured. David, who hails from Belgium, developed this project over many months, and the gun proved to be a true tack-driver, with the ability to group in the Ones, even with the heavy boat-tail bullets. David talks about the build and his reloading methods while action designer Jerry Stiller provides technical insights into the design features of his Viper action.
It was a long journey looking for the perfect custom action to build my new rifle. I searched the internet and visited various forums. I even re-read all my old Precision Shooting magazines to find what I was looking for. One evening I conferred by telephone with Mr. Jerry Stiller of Stiller’s Actions in Texas. He patiently answered all my questions. That moment I decided that I wanted a Viper Drop-Port action. [Editor: Sadly, the Viper Drop-Port is no longer in production.]
Component Selection At the heart of this gun is a Viper action. This medium-sized action can handle cartridges from a small BR up to a 6.5-284. (Stiller’s smaller Cobra action is for PPC and BRs only.) The Viper is milled from aluminum. This keeps weight down while still allowing Vipers to have a large bedding surface like a Stolle Panda.
At first I was a bit sceptical about the aluminum’s toughness, but Mr. Stiller informed me that the action is the perfect marriage between steel and aluminum. The bolt is hard-chromed and the action body is hard-anodized. This gives it two surfaces that resist wear and make an already-slick action even slicker. Stainless steel is used for all the heavy-stress points including barrel threads, locking lugs, and the rear camming surface. The bolt is made of steel with a very light, small-diameter firing pin to prevent primer piercing with heavy loads. Everything is held very concentric to the bore axis. The Viper is a very smooth action mainly because the design and the precise machining of the camming surfaces. Combined with optimal bolt-lift timing, this gives a smooth action. Stiller also keeps the tolerances very tight on these actions, though they are as fast-handling as any you can buy. The trigger is of course a Jewell BR model.
The rifle is chambered in 6mmBR Norma, my favorite cartridge. I have two HV-contour Shilen match barrels, both with 1 in 8″ twists and finished lengths of 24 inches. The chamber has a .266″ neck so neck-turning is necessary. Freebore is .060″ but combined with a 1.5° throat angle this lets me seat a wide range of bullets from 58 grains up to 107 grains.
The stock is a McMillan Edge with moulded-in gray and black marble swirl. I specified 60% black and dark and light gray both at 20%. I went with the Edge stock because I was always pleased with McMillan products and because it had a very low center of gravity. I wanted the barrels very low in the stock because I think it makes the gun track better.
Details of the Drop-Port–with VIDEO! The visible part of the Drop-Port is a cartridge-sized cut-out in the floor of the action. This tapers into a funnel shape that lets the spent case fall nose-first through a single hole in the underside of the stock. The Drop-Port is carefully sized so that empty brass will fall through from gravity but a loaded round won’t. I’ve found that getting a BR case to eject 100% reliably in a standard action is not easy. The round is short and fat so it clears the chamber too early and the ejector pushes the cases out the extractor too fast. This can result in an empty case sitting in your action, no longer held by the extractor. Needless to say, this can slow you down during a stressful competition. When you get a Drop-Port you can forget all those problems.
Failure to eject is NOT going to happen with a Drop-Port. The system just works every time, and it’s FAST. Right-Click on the Media Player image and “Save As” to download a video (6.9 megs) showing me cycling the action during live fire.
One smart feature of the Drop-Port is the extractor location. A Remington extractor is located at the bottom of the bolt. This way the case is supported by the extractor until the front of the case lines up with the cut-out in the action. At that moment the front of the case tilts down and the rim slips out of the extractor. In the stock there is a funnel which collects the case. The case drops out of the rifle through a single small hole in front of the trigger guard.
Building an Accurate Load Tools and Recipes I start with new Lapua cases and after full-length sizing I trim them with a Wilson trimmer. Then I turn the necks for a .264″ neck diameter with a Lapua 105 seated in the brass. After fire-forming I use a “semi-custom” Harrell’s full-length sizing die with bushing. I use a .262 bushing with the moly-coated bullets. This Harrell’s die is the best I ever used — it gives very low run out. [Editor’s Note: Harrell’s stocks a number of dies with various internal dimensions. You send them three fire-formed cases and they’ll pick out a die that fits your brass the best. The cost is very reasonable.] Overall the excellent concentricity I’m seeing with my rounds is a combination of a superb chambering job, a neck-turned Lapua case and the Harrell’s sizing die. The die is supplied with a brass bushing that allows you to measure the amount of sizing you are doing.
For seating I use both a Wilson inline seater (hand die) and a Forster seating die that threads into a press. The latter gets the most use because I find it easier to use. Run out with both is around 0.001″ or better measured on the bullet.
Load development was very easy. I started with Varget and all loads … shot well. Vihtavuori N150 also shot very well with… moly-coated Lapua 105s. To my delight, the light bullets are also shooting very well in the 1:8″ twist. Nosler Ballistic Tips are giving very good results with a case full of N140. I’ve also tried N150, N540 and AA 2520. For all loads I’ve been using CCI BR4. Bullets are seated well into the lands with square marks showing. This gives an overall length around 59 mm (2.32″), depending on the bullet used.
Shooting the Rifle–How It Performs The rifle is very easy to shoot and it is very accurate, but it had some drawbacks in the beginning. First there is the stock. It is designed for bench shooting and on a table it does this very well. I use a Caldwell front rest and a Protektor rear bag. When shooting prone I’ll also use the rest but the cheek weld is not ideal (the Edge was optimized for free recoil shooting from the bench). The rings that are supplied with the action are rather high. I looked around and found some that were lower. This made shooting easier, but I still wasn’t satisfied. The gun was a bit nose-heavy. There is a weight system built into the stock, but it wasn’t enough to bring the gun in balance. I like the balance point to be just in front of the receiver ring. So I cut the rear off the stock and put in a larger tube and turned some weights to put in it. I also made up an aluminum butt plate. Then I installed a Harrell’s brake to cut recoil to a minimum. With these modifications, the rifle is now shooting the way I want. I think the Edge stock is a very good design for benchrest shooting but for prone shooting it has some shortcomings. I think the MBR is a better stock for shooting prone.
Muzzle Brake–Less Recoil, Same Excellent Accuracy After testing the barrel with different loads, I decided to put a brake on one barrel. Most of my guns are muzzle-braked and since I had two virtually identical barrels, I put a Harrell’s brake on one. The barrel had to be threaded to mount the brake and here I was a little concerned–I remembered the advice to “never mess with a winner”. The un-braked barrel was ultra-accurate and I was curious whether the process of fitting the brake might affect the accuracy.
Thankfully, my worries were unfounded. My targets showed no loss of accuracy — there was no evidence that the brake had caused any changes (except as to recoil). I have wondered though, perhaps the brake makes the gun more shootable and in that way compensates for some small accuracy loss that may be there? Whatever the case, the gun shoots just as tight as before, except now it’s a lot more user-friendly with less muzzle hop and less “push” on recoil.
This Rifle Literally Shoots Bug-Holes
And now I come to the end of the story. One day when testing the rifle at 100 meters (with brake installed), I spied a fly on the target. Well now, I thought, here is an interesting “precision shooting” challenge. I put the crosshair on the fly, squeezed the trigger, and the fly was history.
One shot, one kill. Now THAT is impressive precision. If you look closely you’ll see what’s left of Mr. Fly around the bullet hole. Or “bug-hole” as you Americans would say. This kind of performance is a real confidence-booster for the trigger-puller, let me tell you.
The Drop-Port — Simple Yet Advanced
Jerry Stiller tells us: “The drop-port ejects the case out the bottom of the action using only gravity. No ejector plunger is required so the system is as foolproof as anything can be. (A normal spring-loaded ejector creates an uneven load on one side of the case head.) Unlike other ejection systems, micro-ports etc., a Drop-Port doesn’t require tuning or adjusting, and just works. Many top shooters tell us they can cycle rounds faster with a Drop-Port action than with any other design.”
“The engineering of the Viper reflects some key design objectives. I wanted it to be able to fit standard commercially available stocks and have a barrel fit-up that was well known in the industry. I liked the idea of the larger bedding area and higher stiffness of the aluminum actions, so I chose the Panda footprint and barrel tenon for the Viper. I also made some changes to what was available at the time to make the product better. I used a smaller diameter firing pin to eliminate primer piercing, hard anodized all the aluminum parts for corrosion resistance and to make the surface hard and slick. The bolts are also coated for the same reasons.
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, meaning 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’ve been able to shoot consistent quarter-inch, five-shot groups at 100 yards. Cartridge OAL is 2.353″, or 1.990″ measured from the ogive.
The Berger SW Nationals is coming up in a couple weeks. At that match, the sling shooters and F-Class competitors need to haul lots of gear from parking lot to the firing line, and then move from yardage to yardage. Along with their rifles, shooters need to bring mats, front rests or bipods, spotting scopes (with stands), rear bags, ammo boxes, log sheets, tool kits, and heavy coats (for the sling shooters).
