Last week, oppressive legislation was re-introduced in Congress that would ban and confiscate all suppressors (aka “silencers”) in all 50 states. This sweeping suppressor ban is the work of two Democratic party lawmakers, U.S. Sen. Bob Menendez (D-NJ), and Rep. Bonnie Watson Coleman (D-NJ). This unconstitutional legislation is called “HEAR Act”. HEAR stands for “Help Empower Americans to Respond”. The deceptive name falsely suggests this statute was in some way designed to protect hearing or reduce noise pollution.
Just the opposite is true. This misguided legislation would prohibit the importation, sale, manufacturing, transfer, and possession of suppressors. The object is both to ban suppressors AND to confiscate currently-owned suppressors. As GunsAmerica Digest explains: “Emphasis was added on ‘possession’ for the obvious reason. It means even current can owners would be affected!”
Senator Menendez, in a press release, argued that suppressors are very commonly used by criminals, something which is completely and totally false. The mendacious Menendez stated: “Gun silencers are devices designed for a very specific purpose — to suppress the sound of gunfire from unsuspecting victims and reduce the chances they can run, hide, take cover, and call the police during an active shooter situation. [This] legislation that would prevent armed assailants from using deadly devices that only make incidents of gun violence all the more dangerous.”
Sen. Menendez has an interesting reputation in Washington. He was indicted in 2015 on bribery charges, and stood trial in 2017, resulting in a hung jury. And, according to the N.Y. Times and Politico, he is currently under investigation for more questionable practices. SEE N.Y. Times Report.
The sponsors of the legislation do not acknowledge that there is a complex, and expensive process to acquire a suppressor, involving background checks, ATF paperwork, and a costly $200 Tax Stamp. As usual, these Democrats ignore the facts and push legislation based on fraudulent assertions.
Rep. Bonnie Watson Coleman attacked the use of silencers, completely ignoring how they are safely used by hunters and sportsmen throughout the world. Coleman states: “Silencers are not tools of self-defense, they are tools of murder. They have no legal application, which is why law enforcement officials around the country have called for their elimination.”
The HEAR act would ban all future sales of suppressors. In addition, the law would allow confiscation of existing suppressors via a buy-back program using Byrne JAG grants. Current suppressor owners would have a 90-day grace period after the date of enactment to surrender their silencers/suppressors.
GunsAmerica Digest notes: “Not surprisingly, the legislation is backed by a collection of the usual suspects.”
U.S. Senators who are listed as HEAR Act co-sponsors include: Dianne Feinstein (D-Calif.), Ed Markey (D-Mass.), Richard Blumenthal (D-Conn.), Tim Kaine (D-Va.), Alex Padilla (D-Calif.), Mazie Hirono (D-Hawaii), Cory Booker (D-New Jersey), and Sheldon Whitehouse (D-R.I.). Every one is a Democrat.
In the House of Representatives, HEAR Act cosponsors include Reps. Jasmine Crockett (D-Texas), Rashida Tlaib (D-Mich), Eleanor Holmes Norton (D.C.), Wiley Nickel (D-N.C.), Glenn Ivey (D-Md.), Barbara Lee (D-Calif.), and Adriano Espaillat (D-N.Y.). Again all the co-sponsors are Democrats, including some of the most radical legislators in Congress (such as Rashida Talib).
The America Suppressor Association (ASA) has condemned the reintroduction of the HEAR Act.
“ASA is unequivocally opposed to any attempt to ban suppressors. We are unwavering in our support of the Second Amendment and the individual right to possess suppressors. We will fight this tooth and nail. With the facts on our side, we will succeed.”
Read HEAR Act Text Banning Suppressors and Authorizing Confiscation:
With the oppressive Washington House Bill 1240 (HB 1240) being signed into law on 4/25/23 by Washington state Governor Jay Inslee, a legal action has been filed in Federal District Court (Eastern Washington) by several plaintiffs to combat this overreaching legislation. The case, Banta et al v. Ferguson seeks a temporary and permanent injunction based on the unconstitutionality of HB 1240. There is an additional action filed by the Second Amendment Foundation. That other lawsuit, named Hartford v. Ferguson, was filed in the U.S. District Court for the Western District of Washington.
Banta et al vs. Ferguson
The action contesting HB 1240 was filed in the Eastern District of Washington, U.S. District Court. Plaintiffs include Amanda Banta (2012 Olympian Sport Shooter), Sharp Shooting Indoor Range & Gun Shop, The Range LLC, Aero Precision LLC, and the NSSF. The complaint is filed against defendants Robert W. Ferguson, Attorney General of Washington State, and John R. Batiste, Chief of the Washington State Patrol.
“We do not agree with this law and we do not think it is constitutional,” said Scott Dover, CEO of Aero Precision. Dover explained: “HB 1240 bans some of the most common firearms and parts available. It impacts the lawful ownership of products we manufacture and sell to thousands of our customers in the State of Washington. It also restricts the rights of the individuals, Aero Precision employees, who make these parts. We will fight this law in the courts and are confident in the outcome given the clear rulings in multiple Supreme Court cases, including Heller and Bruen.”
Description: Aero Precision has filed a lawsuit in conjunction with several other plaintiffs to combat the overreaching semi-auto rifle ban legislation by the state of Washington.

This custom war wagon hauls varmint hunters around the Longmeadow Game Resort in Colorado.
Will you be heading to the varmint fields this summer? Proper planning is key to a safe, satisfying, and productive varmint holiday. Of course you’ll be busy reloading, but you should 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!”
This photo is from a Dan Eigen TV Show video featuring a P-Dog hunt.
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.
Anyway, on to the rifles…consider bringing a .17 HMR, .223 Ackley bolt gun, .223 Ackley AR, and a .243 WSSM. Some years the .17 HMR isn’t removed from its case. We had a couple windless days and the 17 was lots of fun. I’d walk into the dogtown and then lay down and wait. After five minutes or so I’d have dogs within easy rimfire range, and out to as far as I’d care to stretch the rimfire. 275 yards was about it.”
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. I believe that a rimfire will put you at a distinct disadvantage. The only rimfire that will somewhat work is the .17 HMR and you can reload for your .204s for close to the cost of HMR ammo and you’ll be less apt to be under-gunned. Your .204 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 6XC for those long shots. The classic .22-250 is also a wickedly effective varmint cartridge.
.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.
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.
.17 HMR Savage A17 Varmint Rifle
We also like to have a Rimfire 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.

The TX22 Competition SCR builds features a precision-engineered slide and match-grade bull barrel. The “skeletonized” slide with enlarged ejection port is designed so that a red dot optic can be mounted to the barrel. That helps prevent problems during ejection of empty shells. Taurus claims this mounting configuration enhances accuracy compared to a slide-mounted optic platform.
9. Amazon — NEIKO 6″ Digital Calipers, $25.89

If you’re getting started in reloading or are looking for a back-up set of calipers, this is a good option.
⏺ Good compact muffs for the price with a good 26dB SNR
We say it all the time but don’t ever shoot without quality hearing protection. Consider these Vanderfield folding ear muffs. Priced at just $15.99, these come in a variety of colors (black, brown, green, gray, red, purple, pink) so you can easily tell yours apart from others. The 26dB SNR sound protection rating is above average for compact muffs. For maximum protection use plugs under the muffs. (FYI, “SNR” or Single Number Rating, is the EURO equivalent of the NRR noise rating in the USA.)
You’ve heard the adage — “The couple that plays together, stays together.” Here’s a story about a married couple that competes together in precision rifle matches. Shooters Tim and Regina Milkovich recently both placed in the Top 10 at the popular CowTown Accurized AR Match. Regina took third with a nearly-clean run, dropping only one shot on Stage 5 to end with 49 points and an overall time of 49.50. Tim followed closely behind, placing sixth with 48 points and a time of 37.95.
This match, held at the CowTown Range in Peoria, Arizona, is designed to test and build shooters’ long range skills. Shots are taken from normal PRS-style positions and supports. Each match consists of five stages with targets ranging from 100 to 700 yards. Each stage has a 20-round maximum, and the match typically requires 40 to 50 hits.
Tim and Regina, who are both sponsored by Nosler, can often be found competing together at individual and team matches. At this match, both shot ARs chambered in .223 Rem loaded with Nosler .22 caliber 77gr Custom Competition bullets.
This video is from a Cowtown Accurized AR match last October.
Regina is a Top Female PRS Shooter
Regina is one of the top female precision rifle competitors in the country. She is one of only two women to ever win a national-level Precision Rifle Series (PRS) match. Just a few years ago Regina was a novice in the PRS/NRL game. Now ranked as a Master Class shooter, today she is a respected, top-level competitor.
Time is a Veteran Who Shoots Many Disciplines
Tim is a military veteran with service in the U.S. Marine Corps, U.S. Army, and U.S. Air Force. He has been shooting competitively since 1986 in multiple disciplines including Pistol Silhouette, Bullseye Pistol, USPSA, IDPA, and 3 Gun. Tim has a Master Class ranking in most of the disciplines he shoots.
Tim also shoots bolt-action rifles. Below are his 6.5×47 Lapua cartridges loaded with Nosler 140gr RDF bullets and Varget powder. Photos from Tim Milkovich Facebook Page.
We know many of our readers are getting older and are not as flexible as they once were. If you shoot prone with sling, or do position shooting, you can definitely benefit from doing some key stretches on a regular basis. This can help avoid cramping, muscle pain, or unwanted tension. In addition, doing stretching exercise can help with general health and fitness.
Shooting Sports USA has a good fitness article: Easy Stretches And Strength Movements. While the main focus of this article is on strethces to alleviate lower back pain, many of the movements illustrated can help ease neck, shoulder, and mid-back tension. This Editor, who suffers from neck/shoulder tension, can confirm that these exercises really do help. NOTE: The lead photo above shows the Floor Pec stretch (left) and Pigeon stretch (right), referenced below.
The article’s author, Corey Howard, explains:
Let’s look at the simple stretches … to maintain a healthy range of motion in your four corners — your hips and shoulders. If any of these areas are tight, then nine times out of 10, your body can’t stabilize and you’ll have low back issues.
There are four simple yoga stretches I have all my clients do: child’s pose, floor pec stretch, half kneeling hip flexor, and pigeon. These are simple and can be seen in the photos. The child’s pose lengthens the spine and stretches the lats, the big muscles in your upper back. Pec stretch on the floor opens up your chest and relaxes your shoulders so your posture improves. Half kneeling hip flexor stretch should be felt on the front side of your hips and ease the strain on your lower back. Finally, pigeon stretch can be felt through your glutes and will ease any lower back discomfort.”
Good Basic Stretching Routines — Video Instruction
Here are two videos that offers some other stretching techniques that can help older marksmen. This Editor started doing some of the listed morning stretches. Right away this helped to significantly reduce stiffness associated with working at a computer all day long.
And here is a more aggressive stretching routine that includes some of the stretches found in the Shooting Sports USA article. For older readers — you may want to just do a few of these stretches for starters — not the entire routing.
Jason Baney was one of the “founding fathers” of this website when we started out as 6mmBR.com 18 years ago. A few seasons back, Jason created an interesting wildcat, a mid-sized 7mm cartridge based on the 6.5×47 Lapua case. In this report, Jason (who now works at Eurooptic.com) talks about his 7×47 wildcat and his initial velocity (and feasibility) tests. To determine the 7×47’s velocity potential, Jason did a multi-stage test, cutting a barrel in two-inch increments. This process is illustrated in a video, embedded below.
You may be surprised that the little 7×47 cartridge could drive a 180gr Berger Hybrid at 2770+ FPS with a 32″ barrel and Reloder 17. Max Velocity with H4350 (and 32″ barrel) was roughly 70 FPS slower. With a 24″ barrel length, the 7×47 was still able to propel the 180gr Hybrids over 2600 FPS with H4350. That’s impressive performance for a mid-sized cartridge pushing a very big bullet.
7×47 Lapua Wildcat — Great Accuracy and Surprising Velocity
By Jason Baney, Eurooptic.com
The biggest enemy in long-range shooting is wind. This also happens to be the hardest to gauge and predict. The only way mere mortals can attempt to defeat the wind demons is to shoot a cartridge with the most ballistic efficiency, yet maintain a user-friendly combination of recoil and component consumption as well as performance on target.
The 7mm bullets tend to yield the best compromise of all of these aspects. Their BC-to-weight ratio is outstanding and 7mm bullets provide sufficient impact energy for most situations. In addition to that, the recoil of 7mm bullets can be more manageable than heavier/larger .30 and .338 caliber projectiles.
In cartridge design, of course you want the best case possible. Having used the 6.5×47 Lapua since its release in 2006, I felt this cartridge was the perfect choice to start with as I wanted a true short-action non-magnum round that gave the least possible wind drift to 1000 yards. The 6.5×47 parent case also allowed seating of the heavy 180gr class bullets completely out in the neck yet it maintained an overall length that would actually work in a factory Remington short action magazine.
The 6.5×47 brass from Lapua is as good as it gets and is a very efficient case. The small primer pocket has been a proven winner so no need to change anything. This combination has always given reliable precision and extremely tight velocity spreads.
So here I was, ready to expand a 6.5×47 Lapua to 7mm but a web search revealed no info on a 7×47 wildcat, so test loads would be based purely on an educated guess. My initial assessment/prediction was that heavier 180gr bullets in the larger 7mm caliber would end up at a max load very close to a 140gr bullet in the parent 6.5 caliber. This actually turned out to be a very accurate assumption.
The performance goal of this cartridge was to get a 180gr Berger Hybrid moving at 2720 FPS or faster to be able to shoot inside of a 6.5mm 140gr Berger Hybrid at 2900 FPS. (That 2900 speed is what I was able to achieve with the standard 6.5×47 Lapua). I also planned to try the 168gr VLD as well as the 180gr Lapua Scenar and 162gr Amax, but the specific goal was the beat the 6.5 140gr bullets at 2900 FPS. I believed the 180 Hybrid at 2720 FPS would be the easiest way to accomplish this.
Here are Summary Test Results for H4350 and Reloder 17 for 180s, and IMR 8208 for the 168s. Speeds were clocked by two chronographs at nine (9) barrel lengths, 32″ to 16.1″.
Since this cartridge was a complete unknown I thought it would be quite interesting to see what the 7×47 could achieve at various barrel lengths from very long to very short. We wanted to see which length would best suit the bullet/cartridge combination for max performance. Obviously testing 8-10 barrels at different lengths would be pointless due to natural performance variations between barrels, not to mention expensive and wasteful. I decided instead to attempt a fairly radical test and cut a barrel from 32″ down the 16.1” while chronographing the same loads along the way to see what each combination delivered at the different lengths.
Before I could get started of course a reamer and dies and a few other parts were needed. Dave Kiff at Pacific Tool and Gauge was excited to get going on the project so soon after our phone conversation my one of a kind reamer arrived. Since I had been using Forster dies in the 6mmx47 Lapua and 6.5×47 for all these years, I contacted my friend Bob Ruch at Forster and he was willing to make me a few sets of special dies for the project. Lapua of course provided some brass for the project and Rock Creek Barrels sent a beautiful 1:8.7″-twist 5R barrel blank as a sacrificial lamb. The gunsmith I chose for the chamber job on this project needed to be a tactical long range rifle shooter to appreciate the capability of the round all the way down to its 16.1” barrel length so I asked my good friend Wade Stuteville from Stuteville Precision to help me out.
The rifle I selected for the test was Accuracy International’s new AT rifle. This rifle is basically an overhauled and updated AI AW with a quick user-changeable barrel. I can literally change a barrel in 1 minute or less. The machining they have done to give this function was quite simple and brilliant in the way it retains the barrel yet allows the release quickly and with only a 4mm Allen wrench. This would make the test that I contrived go very smoothly as no major tools were needed.
My goal was to use as many different load combos for the test as I could without making it extremely cumbersome to complete. I wanted to test at least the 180 and 168 Berger as well as a couple different powders representing different burn rates to get an all-around feel for how the cartridge would behave at the different lengths. From previous experience with the 6.5×47, the best powder choices were Hodgdon H4350 and Alliant Reloder 17 (RL17) so these would be the main players. I also picked IMR 8208, Varget, and VV N550 to cover the spectrum of acceptable burn rates. Also, my standard CCI 450 primer was used as that has been successful for me in the 6mmBR and 6.5×47 since 2006 as they are incredibly consistent, however they are also better able to take high pressures without blanking. After picking the powders, I first ran ladder tests to assess max loads in the long 32” barrel.
Velocity Study — Chopping the Barrel from 32″ to 16.1″
Laying out the test actually took a bit of bit of mental gymnastics to provide randomness. The barrel was to be cut in 2” increments from 32” down to a final of 16.1”. Each length was actually pre-scored by Wade to make cutting easier to start and was actually 1/8” long at each mark so when I finally ended up at 16 1/8”, I was able to have the barrel re-crowned without going below legal length.
Six loads were assembled using the five powders mentioned above and two bullets (Berger 168gr VLD and 180gr Hybrid). Each set of rounds to be fired at each cut was predetermined and laid out so that the same load never preceded nor followed another more than once. Reloder 17 and H4350 loads were fired at each cut, while the four others were fired at every-other cut to keep the round count under 200. Twenty rounds (4 loads times 5 rounds each) were fired at each cut from 32” down to 18” and at the final 16.1” length each of the six loads was fired. That is a total of 190 test rounds. The barrel was cleaned before firing at the 24” length and before firing at the 16.1” length. After cleaning each time I fired two rounds of the next load as fouling shots to normalize velocities.
The rifle was fitted with a 3” fore-end attachment and fired from my 40-lb front rest for 1000-yard benchrest competition with a rear bunny-ear bag. Throughout the test, the rifle never changed its position — though the muzzle did retreat 2” with every cut. I used two chronographs for the test. An Oehler 35P was placed 10 feet from the original 32” muzzle and a Magnetospeed V3 was attached on the muzzle (at all barrel lengths down to 16.1 inches.)
After every round of firing, the barrel was removed and we poured cold water on the exterior only and wrapped a wet towel around it to speed cooling. While the barrel was cooling we used a couple C-clamps and a 2×4 to create an impromptu barrel vice to hold it while we were cutting. While it was clamped, we used a simple hacksaw to cut off two inches and crowned the barrel with an RCBS deburring tool for a nice finish. It took an average of two minutes to cut through the barrel at each length.
OBSERVATIONS:
Throughout the test, the rifle lost 3.2 lbs on its way to 16.1 inches. The recoil and muzzle blast increased dramatically from 32″ down to 16.1″. Groups on target were actually quite impressive given that we were not really trying for absolute precision and we had rough-cut crowns. Many groups formed one large hole and several were half-MOA or better – even at the final 16.1″ length.
Each load lost between 12.25-16.8 FPS per inch (loss per inch – LPI) over the entire test, though the rate of the loss varied by the burn rate of the powder and by barrel length. Generally below the 24” barrel length the LPI accelerated rapidly. Initial LPI at the longest lengths was 0-10 FPS, while the loss per inch at the shortest lengths were much higher at 30-55 FPS!
In general I did not quite achieve the velocity I was hoping for, but am very close and intend to test longer throats and different throat geometry to get where I want to be. Below I will break the attainable performance down into 3 barrel lengths for consideration in different disciplines.
APPLICATION ONE: 28-30” Barrel for 1000-Yard Benchrest:
Since I am close to or past my target velocity at the longer lengths (above 2720 FPS with the 180gr Berger Hybrid), I intend to barrel a 1000-yard Benchrest rifle in this caliber and give it an honest try in 1K benchrest. I feel that, with a 28-30″ barrel length, my goal will be attainable and it will pull away from 6.5mm class rounds in the wind drift department. While there will be a slight recoil increase, in a 17-lb rifle it is not a concern. There will also surely be a significant gain in useful barrel life as well.
With spring soon changing to summer, we are in peak varmint season in many parts of the country. In an area with a high number of critters, a semi-auto varmint rifle is a good choice. You get quick follow-up shots, with reliable 20-rd and 30-rd magazines.
For this Saturday at the Movies Showcase we feature a variety of semi-auto, AR-platform rifles chambered for efficient, high-velocity varmint ammo. Cartridges include: .17 WSM, .17 Remington, .20 Practical, .204 Ruger, .22 Grendel, .223 Rem, and 6mm ARC. We conclude with a video that reviews a variety of lead-free .223 Rem ammo types.
Rock Chuck Hunting in Eastern Oregon
This video has some great backcountry footage. The host nails a number of rockchucks with his .223 Rem-chambered AR-15. The shooter says that the default AR-15 cartridge works great for varmints: “The .223 Remington becomes a rockchuck hunter’s friend with the right load: Nosler 40gr Ballistic Tip loaded over a stuffed case of H335 powder. This achieves 3800 FPS with excellent accuracy.”
.17 Remington AR-15 — Small Bullet, Ultra-High Velocity
The .17 Remington wildcat is based on the .223 Remington case necked down to .172″, with the shoulder moved back. High muzzle velocity (4000+ FPS), flat trajectory, and very low recoil are the .17 Remington’s primary attributes. It has a maximum effective range of about 440 yards on prairie dog-sized animals, but the low BCs of the small .17-cal bullets makes them quite susceptible to crosswinds at such distances.
This Varminter.com video was created in spring 2022, just in time for Rockchuck and Thermal Coyote hunts. The host noted: “This was my first experience with the .17 Remington, but I was not unaware of its history and steady popularity among varmint and predator hunters. Although finding an available and affordable .17 Remington bolt-action rifle is nearly impossible nowadays, building one in an AR-15 was simple and straight-forward.” The video has full description of all the components for the build. The .17 Rem is fast — the 25gr bullet runs 3777 FPS from an 18″ barrel (see 01:42 time-mark). READ Full Story.
.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.
Eric Mayer created his own custom .17 WSM AR-15 varmint rifle, built with a Franklin Armory F17-V4 Upper, Aero Precision Lower, and Magpul stock. This was used in California and Arizona. READ Full Story.
.20 Practical — Fast, Accurate, Easy to Form
The .20 Practical cartridge is simply a .223 Rem necked down to .20 caliber. This is a great choice for prairie dogs — and probably our favorite wildcat for the AR-15. Just neck down your .223 Rem brass, fit a .20-Cal barrel and you’re good to go. Robert Whitley notes the the .20 Practical “is a perfect cartridge for varmint hunting and general shooting — very accurate and fast! It functions 100% out of an AR-15.”
The .20 Practical offers some notable advantages for high-volume varmint shooters. 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, and 32-grainers even faster. This makes the .20 Practical a great choice for an AR-based varmint rifle.
.20 Practical Ultimate AR Varminter
A decade ago AccurateShooter.com created a .20 Practical AR15 Ultimate Varminter with a custom 20-caliber upper from Robert Whitley of AR-X Enterprises, LLC. That project rifle was ultra-accurate — every 5-shot group out of the gun was less than the size of a dime. That gun was auctioned off, but Robert Whitley continues to produce custom 20 Practical AR-15 uppers.
You make .20 Practical cases by simply necking down .223 Rem brass to .20 caliber. You can start with standard .223 Rem brass and even load with standard .223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.
Prairie Dog Hunt with .204 Ruger AR — Watch The P-Dogs Fly
The video was created during a 2018 prairie dog safari. It has stunning footage of hits on P-Dogs at multiple distances. You can see over FIFTY hits with some amazing P-Dog aerials. Watch the first flyin’ dog at 00:20 time-mark and there’s a truly spectacular gut-busting hit at 3:13. That shows the potency of a high-speed .20-cal projectile. The shooter was using a custom-built AR-15 chambered in a .204 Ruger. That cartridge was driving 35gr Berger hollow point bullets at a stunning 4050 FPS! The rifle was fitted with a Dakota silencer suppressor and many other custom components. If you’ve never tried prairie dog hunting, watch this video start to finish and you may be hooked.
6mm ARC AR-15 Varmint Rig
This Varminter.com video examines the 6mm ARC cartridge from a varmint hunter’s perspective. Created by Hornady, the 6mm ARC was designed for target shooting and medium-sized game both in bolt guns and Modern Sporting Rifles. Hornady states: “The 6mm ARC … fits in an AR-15-pattern action, functions reliably out of standard-capacity 24- or 17-round magazines. It delivers substantially better ballistics than the .223 Rem[.]” This video examines how the 6mm ARC performs in an AR-15 for varmint and predator hunting. The host reviews available factory varmint loads. The video also examines reloading components for the 6mm ARC — brass and bullets. CLICK HERE for full article.
Cottontail Rabbit Hunting with Suppressed .204 Ruger AR-15
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.
The .22 Grendel is an extremely accurate and efficient cartridge based on the 6.5 Grendel necked down to .22 caliber. The case can drive 55gr varmint bullets at high velocities — over 3500 FPS. With a faster-twist barrel you can load up to 90gr bullets at 2500 FPS. The tester achieved velocities close to a 22-250. The short, fat case fits in AR-15 magazines, but may not feed as reliably during rapid fire. The tester did experience one double-feed.
Lead-Free Ammo Offerings Tested in .223 Rem AR-15
Some states — such as California — prohibit hunting with bullets that contain lead. If you plan to hunt in an area with such restrictions, you’ll need to find a lead-free substitute. Thankfully a number of manufacturers produce ammo with solid brass projectiles or other lead-free bullet designs. This Varminter.com video reviews .223 Remington no-lead ammunition from Cor-Bon, Hornady, Nosler and Winchester. These ammo types were tested in a AR-15 varmint rifle, used in a coyote hunt featured at the end of the video. SEE Full Story on Varminter.com.

Rep. Bonnie Watson Coleman attacked the use of silencers, completely ignoring how they are safely used by hunters and sportsmen throughout the world. Coleman states: “Silencers are not tools of self-defense, they are tools of murder. They have no legal application, which is why law enforcement officials around the country have called for their elimination.”
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.
