Varminting for Fun — With Rimfires and Centerfires
One of the most fun things you can do with a rifle is to shoot varmints such as ground squirrels, prairie dogs, rockchucks, and groundhogs. There’s great satisfaction making a perfect hit on a critter that sends the beastie spinning in the air. Varminting also affords a great excuse to acquire more rifles, because it really does make sense to own and use multiple varmint rifles in various calibers.
Having multiple rifles on a varmint safari lets you preserve barrel life, and shoot lesser-recoiling calibers at the shorter distances. For example, with California ground squirrels, we like a .17 HMR inside 125 yards, then switch to a 20 Practical (20-223 Rem). For prairie dogs, you may want that 20 Practical, plus a nice .22 BR for 250-400 yards, and a .243 Ackley (or 6XC or 6mm CM) for long shots.
Seven Varmint Rifles — Rimfire and Centerfire
With 980,000 subscribers, the Backfire YouTube Channel is highly popular. The capable hosts provide honest, candid reviews. This video covers seven different varmint rigs. First off is the Air Arms TX 200 (00:25). Then the excellent .22 LR CZ 457 is featured (01:33), followed by a .223 Rem AR15-platform rifle (02:30). Next up is the .22 LR Christensen Arms Ranger 22 (03:40), which proved to be “crazy accurate”. Then the video showcases a Bergara Premier in 22-250 (04:20), an “excellent coyote gun that you could use on varmints as well”. Last up is the Ruger American Predator (05:20) in .17 HMR.
6XC Rifle Featured in Gunwerks Rockchuck Adventures
This Gunwerks video showcases varmint hunting in the Western USA. In this video Aaron Davidson and the Gunwerks crew try out some new rifles on some rockchucks. Most of the the rifles were suppressed but the host said the rockchucks took cover after the first shot, so this required good coordination among shooters and spotters. A 6XC varminter is featured at 2:44 and there’s some nice drone footage starting at 2:00.
6mmBR for Longer Range Varmint Adventures
The video creator reports “I spent a great deal of time deciding what 6mm cartridge I would pick for my next varmint build. I was sure of certain things. First, it had to fit an action that I owned. Most importantly, it had to be highly accurate, with light recoil. Quality, highly frangible bullets had to be available in the 50 to 70 grain weight range (for smaller to larger varmint hunting). For flat shooting ballistics, I wanted velocity above 3300 fps. I decided that the 6mmBR, with a slow twist barrel, was what I was looking for.” Components for this rifles are: Borden Alpine Action, Krieger Barrel, Grayboe Ridgeback Stock, Bix’N Andy Trigger, Thunderbeast Ultra Suppressor.
.22-250 Nails Ground Squirrels and Rock Hyraxes in South Africa
Here’s an interesting video from South Africa. The video maker starts with shots on ground squirrels. His .22-250 blasts them into little pieces. They he switches to more distant targets, a furry ground-hog size animal called the Rock Hyrax, Cape Hyrax, or Dassie. Mature Rock Hyraxes weigh 4-5 kilograms and have short ears and tail. These Rock Hyraxes are found at higher elevations in habitats with rock crevices, allowing them to escape from predators (but not skilled varmint hunters).
20 Practical — Great Choice for AR-Platform Rifle
If you want to use an AR-platform rifle in the varmint fields, consider getting a 20-caliber barrel chambered for the efficient, low-recoil 20 Practical cartridge. The 20 Practical is simply a .223 Remington necked down to 20 caliber. The parent .223 Rem cartridge of course works great in an AR, but the 20 Practical offers some notable advantages for high-volume varmint shooters. The 20 Practical cartridge is simply the .223 Rem necked down to 20 caliber — you can use standard .223 brass and load with standard.223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.
The 20 Practical delivers very high velocity with very low recoil while still providing outstanding accuracy. The 20 Practical is great option for folks who favor “fast and light” — smaller, lower-mass bullets traveling at very high velocities. This little cartridge can launch 40-grainers at over 3900 fps.
.17 WSM — The Most Powerful .17 Cal Rimfire
We think that every varmint hunter should own a nice .17 Cal rimfire rig. Out to 200 yards or so the .17 WSM or .17 HMR is very effective on small varmints. It’s nice to be able to shoot affordable ammo out of the box and not have to scrounge for hart-to-find powder and primers. This video features a superb .17 Cal varmint rig, the Primal Rights TS Custom chambered for the impressive .17 WSM cartridge.
Prairie Dog Hunting with .17 HMR Savage A17 Rifle
On varmint excursions, we like to have a .17 rimfire for the closer shots, inside 150 yards. 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.
Varminters now enjoy three .17-caliber rimfire options. The .17 Mach 2, .17 HMR, and .17 WSM are all good choices, with the 17 Mach 2 (17 HM2) being the cheapest and the .17 WSM the most powerful. With a 3000 fps MV, the .17 WSM has some really impressive ballistics, — with a much flatter trajectory than both the .17 HMR and .22 WMR:

What does a three-time High Power National Champion choose for PRS comps? A set of twins. Twin rifles that is. SFC Brandon Green of the USAMU is one of America’s best marksmen. He’s excelled in Service Rifle and High Power disciplines, and now he’s getting very serious about the Precision Rifle Series (PRS). Brandon recently took delivery of “Twins” — two impressive rifles optimized for PRS competition. Green told us: “The Twins are ready for business! The silver one is a 6XC and the black one is a 6.5×47 Lapua”. Both rifles feature Impact Precision actions (with AICS-type mags), 24″ Proof stainless barrels, and Fat Bastard muzzle brakes. Rifle work was done by Stuteville Precision (Wade Stuteville) and Exodus Rifles (Joe Walls).
In the 6XC, Brandon runs Berger 105gr VLDs in Norma 6XC brass. For the 6.5×47 Lapua he shoots 140gr Berger Hybrids or 143gr Hornady ELD-Xs in Lapua brass. Both rifles have stainless steel Proof barrels, but the 6.5x47L has a matte black Cerakote finish.
Brandon loves his new Twins. He said he likes the “feel” of the guns with the Foundation stocks: “These rifles weigh around 17 pounds with optics. They feel very solid under recoil — without the ‘tuning fork’ vibration you can get with a metal-chassis gun. They feel like a good wood-stocked gun, but the material is stronger and more rigid than wood. I’ve heard that guys are having success with these Foundation stocks with the actions installed without pillars or conventional bedding.” Currently Brandon is running both guns without action-screw pillars. He did have one skim-bedded, but he doesn’t think that was really needed. “Both rifles hammer now”, Brandon tells us.
Green Runs Vortex Razor HD Gen II 4.5-27x56mm FFP scopes on both rifles:
High-Tech Micarta Stock Material
At first glance, those stocks may look like wood, but they are actually a special “Micarta” material that is strong, durable, and stable. Micarta, often used for knife handles, is a “a brand name for composites of fiberglass, carbon fiber, or other fabric in a thermosetting plastic.” The stock-maker, Foundation Stocks, says Micarta offers some distinct advantages over laminated wood or conventional fiberglass: “The solid block of material gives us a dense, homogenous material that is absent of any voids or air pockets commonly found in composite stocks. The high compression strength of the material allows us to build an action/DBM specific stock that requires no bedding or pillars. The material is very durable and stable in extreme environments. We use advanced CAD software to design and model our stocks, working in conjunction with action manufacturers and rifle builders to provide exact fitment.”
Here is a close-up of a Foundation Stock showing the distinctive Micarta texture:
Tactical Competition vs. NRA High Power Competition
Brandon says PRS competition is tough: “PRS can be pretty humbling, but it’s been a lot of fun and a great challenge. For a shooter (like me) with a Service Rifle/High Power background, the variations in stages combined with the time limits can be very challenging. And the unusual shooting positions put a new spin on things. PRS is definitely a different ball game, but I really enjoy it.”
SFC Brandon Green honored as the 2015 High Power National Champion. Brandon also won the HP Championship in 2013, and in 2018.
Life before the Twins… Here is Brandon, with his previous PRS rig, at the MasterPiece Arms Precision Rifle Shootout, a PRS event at the CORE Shooting Solutions Range in Florida:
Three-time National High Power Champion SFC Brandon Green (left above) set four new National Records at Camp Perry in 2017, when he won the Service Rifle Championship.
When He’s not Competing in PRS, Brandon Excels with his Service Rifle
This video shows SFC Brandon Green shooting his modern AR Service Rifle in the off-hand (standing), prone (2:20 time), and sitting (3:25 time) positions in competition.
SFC Brandon Green is a shooting superstar. Green won his third NRA National High Power Rifle Championship in 2018 at Camp Atterbury, Indiana. He dominated the High Power Championship cycle, finishing eight points and ten Xs ahead of his nearest competitor. Brandon also won High Power National Championships in 2015 and 2013. And in 2017 he set new records at the CMP’s National Trophy Matches at Camp Perry, winning the Service Rifle title. One of the greatest marksmen in the nation’s history, SFC Green excels at all positions, both rapid-fire and slow-fire.
With all the buzz about the 6.5 Creedmoor and its 6mm Creedmoor little brother, some folks forget that we’ve had an outstanding mid-sized, Across-the-Course cartridge for a long time — the 6XC. Pioneered by 11-time National High Power champion David Tubb, the 6XC has won national High Power championships, excelled in mid-range prone matches, and performed great in the varmint fields. It has also been used successfully by many Precision Rifle Series competitors. It’s no wonder — the 6XC has less recoil than a 6.5mm Creedmoor, there is a great selection of superb 6mm bullets, and Peterson 6XC brass is high-quality and reasonably priced ($69/100) from DavidTubb.com. Fine Norma 6XC brass is available from Grafs.com.
PRS Rifle with Modern 6XC II Chamber
Forum member Grimstod posted this new 6XC II rifle in our long-running Pride and Joy Rifle Thread. Grimstod notes: “These 6XC Gen IIs seam to be a hot commodity lately. This one is for PRS. It features a Premier Accuracy Atlas action made by Kelbly. The bolt and heavy-taper, fluted barrel are Cerakoted to match. I really like the ejectors on these Atlas actions. The stock is a KRG X-Ray painted in Premier Accuracy exclusive colors. The Kelbly Atlas action does not have any modifications. So far every Kelbly action we have tried has had perfect timing and trigger fall. We have been supper pleased with them. I look forward to using a lot more of these excellent actions.”
What is the 6XC II you may ask? That designates a 6XC with a chamber dimension optimized for Norma brass. It turns out that Norma brass is a bit bigger at the bottom than the 22-250 brass from which the 6XC originated. Robert Whitley of 6mmAR.com has created two new JGS reamer specs that fit the Norma brass perfectly, improving feeding and extraction. Here is Robert’s Report:
The 6XC II Chamber — Upgraded for Today’s Norma 6XC Brass
by Robert Whitley of 6mmAR.com
The 6XC II Chamber works perfectly with the Norma 6XC brass and resolves the “sticky bolt lift” issue. The original 6XC chambering was designed based off the usage of 22-250 brass which typically has a web diameter in the range of .461″-.463″. The area of the chamber just forward of the web on the original 6XC chambering was .4695″ which left plenty of clearance.
When Norma 6XC brass became available Norma appears to have developed the base of the case from the .308 Winchester line of cases which have a larger web diameter. The web diameter of the Norma brass typically measures right around .4685″ which leaves almost no diameter clearance.
As shooters would use Norma 6XC brass in an original 6XC chamber they typically would experience “sticky bolt lift” due to the lack of clearance and the fact that the large web diameter of the brass prohibited the re-size dies (no matter how small the base diameter was) from squeezing the brass down enough to create sufficient clearance. The 6XC II chamber resolves this issue. You can order 6XC II sizing dies from 6mmAR.com that work perfectly with this re-designed chambering. 6XC II die sets are in stock now — call (215) 348-8789 to order.
6XC II Long Range Reamer (Throated long for 105-115gr Bullets):
The 6XC II-LT reamer below is throated long to keep the full bearing surface of 110-115gr bullets forward of the neck/shoulder junction of the case. Note, 6mmAR.com has also developed a shorter-freebore version for 6mm bullets with shorter bearing surface. SEE shorter 6XC II Reamer Print.
6XC II Chamber and Sizing Die Combo:
- Resolves the “sticky bolt lift” problem shooters experienced using the Norma 6XC Brass in the original 6XC chambers.
– Chamber accepts all 6XC brass or ammo with no modification. Take your existing 6XC brass or ammo and use it without issues.
– Works well with existing Norma 6XC brass, or 6XC brass made from re-formed Winchester and Remington 22-250 brass.
– 6XC II Sizing dies and die sets are available from 6mmAR.com and in stock.
If you are looking for someone to chamber your rifle or re-barrel an existing rifle in the 6XC II chamber, Fred at Sabreco, Inc. in Skippack, PA, (610) 584-8228 can help you. He has the reamers for the cartridge as well as the head space gauges for the cartridge, and has had extensive experience chambering many barrels and rifles.
There an excellent YouTube channel, THLR.NO, that offers videos for long-range hunters and marksmen. The channel’s creator, Thomas Haugland, is a serious, knowledgeable shooter, who takes his rifles out into the field, in all conditions. The THLR.NO channel offers solid advice on scopes, reticles, wind-reading, field positions, and much more. Haugland’s team puts a wide variety of gear through serious field tests — every thing from suppressors to packs to the latest electro-optical hardware. In addition the THLR.NO channel provides good advice on stalking techniques and hunting skills. Here are some recent videos that can help any rifleman.
How to Shoot Better with a Hunting Rifle
This “must-watch” video has great practical advice for hunters. It illustrates proper hand-hold and head position, and shows how to stay steady when breaking the shot. Even competition shooters can learn a few things. One viewer notes: “This was very informative. The footage through the scope showing how one’s position moves the sight alignment was particularly helpful.”
How to Gauge Wind Speed and Hold Off Using Reticles
This field video shows how to observe natural indicators — trees and vegetation — to estimate wind velocity. Then it shows how to calculate hold-offs using the reticle hash-marks. Thomas shoots a fast-cycling Blaser R93 rifle with Norma 6XC ammunition.
If you like these three videos, there are hundreds more on the THLR.NO YouTube channel. In addition, there is an excellent long-format video, Longrange Shooting 2, available on DVD or Vimeo on Demand. This impressive outdoors video features Thomas Haugland and Ulf Lindroth. Here is a preview:
Own a Ruger Precision Rifle (RPR)? Looking for the single best hardware upgrade that will improve inherent accuracy and shot-to-shot consistency? Here’s your answer. Krieger Barrels is now producing Pre-Fit barrels for the RPR in seven popular chamberings: 6XC, 6mm Creedmoor, 6.5 Creedmoor, .243 Win, 6.5 PRC, .308 Winchester, and .300 Win Mag. These $550.00 “Drop-In Ready” barrels come finish-chambered and threaded to fit the Ruger action. The Ruger barrel attachment system allows correct headspace with a pre-chambered barrel. Krieger explains: “Thanks to Ruger’s proprietary barrel nut design, a competent gunsmith will be able to swap out your barrel using an AR15 barrel wrench and proper headspace gauges.”
Kreiger’s 6.5 Creedmoor RPR barrel is an 1:8″-twist with 26″ finished length, 0.750″ at muzzle. The .308 Win RPR barrel is a 1:10″-twist with 24″ finished length, also 0.750″ at muzzle. Both these Krieger RPR Pre-Fits feature muzzles with factory-spec thread so you can re-install the factory muzzle brake.

Do You Like H4350? Then You Should Try Reloder 16 — It Is Accurate and Temp Stable
Alliant Reloder 16 is used now by many top shooters for cartridges that work well with Hodgdon H4350. In fact, we’d say that Reloder 16 is the best substitute for H4350 on the market. Alliant’s RL 16 is very temp stable, offers good velocity, and the accuracy is top tier. Some guys report slightly better accuracy than H4350 in the .284 Win, .260 Rem, 6.5 Creedmoor, 6mm Creedmoor, and 6XC cartridges. If you currently use H4350, you should definitely give Alliant Reloder 16 a try. The powder also boasts excellent lot-to-lot consistency and contains a proprietary de-coppering additive.
This is NOT just a slower version of Alliant’s double-based Reloder 15 (which words great in the 6mmBR and Dasher cartridges). Reloder 16 is a completely new formulation, produced in Sweden by Bofors for Alliant. Reloder 16 utilizes TZ technology, which manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures. As a result, Alliant’s Reloder 16 offers truly outstanding temperature stability.
Match and Hunting Cartridge Applications:
Alliant tells us that Reloder 16 “is ideal for traditional hunting cartridges, such as .30-06 Springfield and .270 Winchester, as well as 6.5mm target loads and tactical applications wherein temperature stability is required.” We also think the powder will work well in these popular match cartridges: 6XC, 6mm Creedmoor, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, .260 Rem, .284 Win, and .300 WSM. For example, Alliant’s Reloder 16 Load Data Page shows a 2932 FPS load with Berger 130 grain Hybrid bullet in the 6.5 Creedmoor.
Alliant Reloder 16 Load DATA for 6.5 Creedmoor:
Alliant Reloder 16 Load DATA for .243 Winchester:
NOTE: This is a partial .243 Win Data set. More loads available HERE.
With all the buzz about the 6.5 Creedmoor and its 6mm Creedmoor little brother, some folks forget that we’ve had an outstanding mid-sized, Across-the-Course cartridge for a long time — the 6XC. Pioneered by 11-time National High Power champion David Tubb, the 6XC has won national High Power championships, excelled in mid-range prone matches, and performed great in the varmint fields. It has also been used successfully by many Precision Rifle Series competitors. It’s no wonder — the 6XC has less recoil than a 6.5mm Creedmoor, there is a great selection of superb 6mm bullets, and Norma-made 6XC brass is high-quality and reasonably priced from DavidTubb.com.

Lyman Handbook Includes Articles by Leading Experts and Top PRS Shooters
The new handbook also includes articles by top PRS shooters and industry experts. Articles such as “PRS How-To” and “Rifle Systems for PRS” by Matt Gervais provide expert info and tips and techniques to start competing. An authoritative article by Hornady’s Dave Emary, “The History and Design of the 6.5 and 6mm Creedmoor” explains why these cartridges have become so popular for PRS and other applications. Emary’s “Reloading Considerations for Long Range Ammunition” is also highly recommended for both novice and experienced hand-loaders.
“As the leader in reloading data, we saw a need for an accurate and reliable source of reloading data for these precision, long-range loads,” said Trevor Mullen, Lyman’s Global Marketing VP. “Our process of compiling a new reloading handbook … is to work with the best in their field — reloaders, the manufacturers of ammunition and rifles, participants in the PRS sport, and our own staff of highly-skilled, highly knowledgeable test shooters. This new handbook [will help] those looking for that edge in PRS competitions.”
The “Long Range Precision Rifle Reloading Handbook”, priced at $16.98, will be available soon from online retailers. Within a short time you can also purchase the book from the Lyman web store. (It is not yet in stock).
