With the variety of rimfire disciplines, from cowboy action to Olympic three-position smallbore, there are countless different rimfire designs on the market — bolt guns, lever guns, single-shots, toggle-links and more. These may shoot the same ammo, but they certainly vary in looks and ergonomics. This is testimony to human creativity.
In our Shooters’ Forum, you’ll find a long-running thread showcasing rimfire rifles for plinking, hunting, 3P Target Shooting, Silhouette, Rimfire F-Class, NRL22 and more. Here are some of the notable recently-posted rifles in that Forum thread, with brief build/component details.
ARA Benchrest Rifle with Stiller Action, Shilen Ratchet Barrel
Forum member Peebles24 showcased his cool flame-paint-job .22 LR benchrest rifle against a scenic, snowy background (never too cold to shoot right?). “I had a new rifle built this past fall by Mark Penrod at Penrod Precision. Stiller 2500X action, Shilen ratchet barrel, Jewell trigger, McMillan stock, Harrell’s tuner, Sightron SIII 10-50×60mm glass. I’m shooting it off my Arnold Machine one-piece rest made locally by Cliff Arnold. I visited the Lapua Testing Center East and got a case of Midas+.” For ammo testing results, click photo at right.
In late April the gun competed in its first ARA benchrest match in Wabash, Indiana.
Beautiful MasterClass-Stocked Rifle for Rimfire F-Class
Here is a handsome rifle belonging to Forum member Redd. Set up for prone Rimfire F-Class-style competition, this rig features a Shilen Ratchet barrel with Erik Cortina Tuner fitted to a Stiller 2500X action. It boasts a beautiful MasterClass figured Walnut stock and rides on a SEB Joy-Pod bipod up front. The optic is a Nightforce 40x45mm Competition.
CZ 457 .22 Magnum Transformed with KRG Bravo Stock
Forum member JAS-AS purchased a .22 Magnum CZ which he revived as a training rig with a new stock. He posted: “I use a CZ457 in .22 Magnum mainly as a trainer — bipod and rear bag kind of stuff. It has evolved over the last year or so. Next change will be a Lilja barrel. This because it can shoot brilliantly (at times) but not consistently. And accuracy degrades as it gets minimally dirty. Also, it doesn’t like 40gr rounds — the groups open up to 1.5 MOA. It’s at its best with 30 and 35 grain rounds running at up to 2250 fps. I believe that to be a twist-rate issue.”
The “Before” photo shows the rifle “as purchased” with a Nikon Monarch 4-16x42mm mildot scope. The “After” image shows the CZ 457 as modified. JAS-AS notes: “I added a bunch of stuff: KRG Bravo stock, Vortex Strike Eagle 5-25x56mm FFP scope, new bipod and Precision Underground bag, trigger spring. With this setup I shoot at 100 yards+ exclusively.” Show at right is a 9-shot group with the rifle at 100 yards. Three-shot groups at 100 have been below half-MOA.
Savage Mark II Squirrel/Field Rifle
This Savage Mark II rifle isn’t fancy, but it has brought much satisfaction to its owner, Forum member “Ohio Varmint Shooter”. He posted: “Just a nice field gun. Less than $200 (without scope). Cheap wooden stock, thin pencil barrel. My squirrel/field gun. There is absolutely nothing special about this… except it’s lefthanded. It shoots fine, preferring CCI standard velocity rounds. I did splurge and put a more-than-needed scope on it. Most scopes with fixed parallax (in this category), have it fixed at 50 yards. I wanted variable parallax so I could set it at 35 yards. I don’t know if it really makes any difference, but I do try to go for accurate head shots. The scope is also a little overkill in magnification, but it does help with the head shots and my aging eyes.”
“As a youth in the 70s, I always dreamed of a left-handed bolt. So getting back into shooting/hunting about 8 years ago, I was delighted to discover this gun. Growing up I had a semi-auto 22, but being a lefty … it would spit powder on my face.” — Ohio Varmint Shooter
Tikka T1x Action in Eliseo Competition Machine Chassis
Here is Gary Eliseo’s personal Rimfire Match Target Rifle with Tikka T1x action. The T1x action is carried in Competition Machine Rimfire Chassis. Gary also posted some recent 100-yard groups, using SK rifle match ammo in this rifle. Gary runs Competition Machine LLC and produces the chassis system for this cool rig, along with outstanding Across-the-Course, High Power, and F-Class chassis systems for rimfire and centerfire rifles.
Vudoo Action Benchrest Rifle with Benchmark 3-Groove Barrel
Here is a classy benchrest rig belonging to Forum member FCJIM. It features a Vudoo LBRP action, Benchmark 3-groove barrel, Harrell’s Precision tuner, NightForce Benchrest scope, and McMillan Edge stock. The stock work was done by Doan Trevor, while FCJIM did the metal work himself, using a Nevius reamer. This rig likes to shoot ELEY Black and Lapua Midas+ ammo.
Last but not least, here is a “blast from the past”. This classic lever-action single shot is crafted by CPS Rifles (Paul Shuttleworth), a boutique gun-maker specializing in single-shot rifles, particularly reproductions of the Stevens 44 1/2. Note the richly-figured wood and the lovely color case-hardening on the receiver. There is a dual Set Trigger system. You pull one trigger through a relatively long stroke until it clicks. The the second trigger breaks the shot (and drops the hammer) with just a few ounces of pull weight. This rig, fitted with MPA Vernier-type tang sights, belongs to Forum member “Mills” from Texas.
The popular BarrelCool is a compact barrel-cooling device that also serves as an empty-chamber safety flag. A small, battery-powered fan drives cooling air through the barrel’s bore. Yes it really works — manufacturer-provided data shows that BarrelCool significantly reduces the time it takes to cool down a hot barrel. Look at the chart above to see what to expect.
In the past, folks have tried various methods to cool barrels: water flushed through the bore, CO2 tanks, even battery-operated fish pumps. BarrelCool is a simpler, less costly, and much handier solution. Priced at $39.99, this small device can definitely save you time at the range. Potentially it can save you money by extending barrel life. To see how Barrelcool works, watch th videos below that show the BarrelCool units in both bolt-action and AR-type rifles.
BarrelCool Range Reports from Forum Members
Forum members have been impress with the BarrelCool device. Member Comrade Terry said: “At the range, I spend a good bit of time waiting for the barrel to cool between shot strings. I fired my usual 50 rounds today, and (though it was 85° today) I was able to leave the range 30-40 minutes earlier than usual thanks to the BarrelCool. I like it!” Another Forum member, J-Rod, reports “Did some load development on my new rifle. This used to take forever due to the barrel heating up outside in full sun (90° ambient). I’d say this little gem cut about two hours off my normal shooting time. I got home early and the wife was happy — what’s that worth?”
How and Why BarrelCool Was Invented
BarrelCool originated from the idea that cease-fire periods would be a great time to cool a barrel. During cease-fires, most ranges and matches require empty chamber flags in the gun so that the range officer and everyone on the firing line can see visually that the gun is in a safe condition. The BarrelCool does double duty — cooling the barrel while serving as an empty-chamber indicator.
BarrelCool inventor Bryan Sumoba explains: “Previous barrel-cooling methods required additional steps such as running patches down the bore, or a fan that gets in the way of a required empty-chamber flag. BarrelCool now allows the shooter to cool the barrel while having the empty-chamber flag in the firearm.”
Sumoba says BarrelCool significantly shortens the time needed to cool down a hot barrel: “In controlled testing, it took about half the time to cool the barrel from 140 degrees F to 100 degrees F. Our customers also report significant reductions in the time it takes to cool down a hot barrel. At an F-Class match in Sacramento, one shooter fired 25 shots out of his 7mm RSAUM and got the barrel to the point where it was too hot to touch. We placed BarrelCool in his firearm and within 30 minutes, the barrel was back to near-ambient temperature.”
Using three (3) CR123A batteries, a BarrelCool unit can operate for 7-10+ hours. BarrelCool fits both AR-style rifles as well as most bolt action rifles. The Hi-Viz yellow color stands out on the firing line and BarrelCool is small enough to fit in most range or gun bags. Manufactured in the USA, Barrelcool can benefit competition, precision, or recreational shooters who need to cool down their barrels more rapidly, while displaying “safe condition” on the firing line. For more information, or to order for $34.99, visit www.barrelcool.com.
BATTERY TIP: We recommend rechargeable CR123A batteries for use in the BarrelCool. These can last many seasaons and can be charged at home or in a vehicle. Keep a spare set in your range bag. A 4-pack of C123A Lithium Batteries with USB recharger unit is $29.99 on Amazon
Take a look at that unusual target below. We bet you’ve never seen one of these before. It’s a 50-Yard Sighting Target for the M1 Garand (and other .30-06 Springfield vintage military rifles). It’s designed to allow a rifleman to confirm his zeros for multiple yardages all the way out to 1000 yards. But importantly, he can establish those zeros at a very “short” shooting facility, since the target is positioned at a mere 50 yards.
Here’s how it works. The target is placed at fifty (50) yards. You start at the bottom, aiming at the black circle. Then check your come-up table and work your way up, clicking step-by-step to the various horizontal lines set for 200, 300, 500, 600 and 1000 yards. This is NOT “spray and pray” — you need to have a pretty good idea of the clicks you need, based on your ammo’s ballistics. This target is calibrated for the U.S. Military M72 Ball Ammo. The targets are available from Champion’s Choice ($0.75 each) or from Creedmoor Sports (12 for $5.95).
Kevin Thomas used this target to get zeroed for a D-Day Anniversary Match at the Talladega Marksmanship Park a few seasons back. Kevin used the target for both his M1 Garand as well as his M1903A1 Springfield, both chambered for the .30-06 Springfield cartridge.
Zeroing at a Short Distance — How to Use the 50-Yard Sighting Target, by Kevin Thomas
As part of my preparation for the Garand Match at the CMP’s Talladega Marksmanship Park, I needed to zero my new M1 Garand, but I was crunched for time. I didn’t have time to get to my normal range and confirm zeros at actual yardages. But a 50-yard zero target came to the rescue. Made for M1s using the M72 National Match ammo, the target allows the shooter to establish fairly good zeros at 200, 300, 500, 600 and 1,000 yards if you’ve got access to a 50-yard range.
I have no idea when these 50-yard Sighting Targets were first developed, but they’ve been around for at least as long as I’ve been involved in this game (longer than I care to admit). It consists of a tall target, with a smallish black bullseye located at the bottom center. The bullseye is an aiming point only. Extending through the top of the target is a vertical line that runs directly up the center, to nearly the top of the paper. Across this, there are intersecting horizontal lines that are marked 200, 300, 500, 600 and 1,000.
The target was designed for the M1 Garand rifle using then-issued M72 National Match ammunition. This ammo launched a 173gr FMJBT bullet at approximately 2,640 FPS. It was a good load in its day, supersonic out to the 1,000-yard line. While that ammo is fairly scarce these days, this isn’t a problem for the handloader. My standard match load for the M1 Garand utilizes the 175gr Lapua Scenar HPBT, and delivers remarkably similar ballistic performance. Thus my normal Garand load translates nicely to this 50-yard target. Yes, this is by design. No point in reinventing the wheel when Lake City has already established what works!
In use, the shooter sets the target up at a measured 50 yards, and (this is critical) checks the vertical line with a plumb bob or a carpenter’s level, to ensure that it is absolutely vertical. Once the target is set, the rifle is fired and the group noted. From there, it is a simple matter of zeroing it normally to bring the groups into alignment with the vertical line, at the elevation needed for a particular range. Once your group is hammering the intersection of the vertical line and the horizontal line marked “200”, you have established your 200-yard zero for that rifle. Record the number of clicks, and you’re good to go. Raise the impacts up to coincide with the line marked “300” and you now have a 300-yard zero as well. And so on, right up the target. Record those settings in your data book, and you’re ready to go to the range at the full distances. If done carefully, you may be in the X-Ring, but at the very least, you’ll be well-centered and ready to get some hard dope recorded for future shoots.
The same target can also be used with an M14/M1A, at least at the shorter distances. The ballistics of the M118 and the current M118LR are similar enough that this will get you on target at the full distances, probably requiring just a half MOA or so change from the 50 yard zero you recorded. Same bullets, moving at a slightly more sedate 2,550 fps, you’ll be in the ballpark at least.
Barney M. Auston of Tulsa, OK with rifle he built to break NBRSA record and win $250 cash award from Sierra Bullets. (From cover of Precision Shooting magazine. May 1956).
Way back in 1955 Sierra Bullets offered a $1000 prize for anyone setting a new Aggregate benchrest record with a 6mm (or larger) bullet. At the time the .222 Remington ruled the roost, and Sierra wanted to promote the larger caliber. (NOTE: That was serious money in 1955 — the equivalent of $10,187 in current dollars corrected for inflation). Sierra also offered a $250.00 prize for a record-breaking performance with any size caliber (including the .22s). Here is the story of how a Tulsa shooter claimed the $250.00 award with a world-record-setting Aggregate involving 10-shot groups at 100 and 200 yards.
Barney Auston’s record-setting rifle was built on an FN Mauser action with double set trigger, with a Hart stainless steel barrel, 30″ x 1 1/8″, chambered for the .222 Remington cartridge. The stock, made by Auston, has a hydraulic bedder as made by L. F. Landwehr of Jefferson City, MO. The scope is a 24X, 2″ inch Unertl. Mr. Auston shot 50gr bullets, custom made by W. M. Brown of Augusta, Ohio, with .705″ Sierra cups and soft swedged. His powder charge was 21 grains of 4198. The rifle rests, both front and rear, were also made by Auston.
Record-Setting Performance
On August 20, 1955, shooting at night in a registered shoot on the John Zink range near Tulsa, Oklahoma, Barney M. Auston of Tulsa broke the existing National Match Course aggregate record. As the first person to do that in 1955, Auston won the Sierra Bullets $250 cash award. Here is the original Sierra Bullets prize offer from 1955:
10-Shot Groups at 100 and 200
Mr. Auston’s winning Aggregate for the National Match Course (five 10-shot groups at 100 yards and five 10-shot groups at 200 yards) was .4512 MOA. He also broke the 200-yard aggregate with an average of .4624 MOA, beating the .4801 match MOA record set by L.E. Wilson only a month earlier.
Barney Auston was a custom rifle maker in Tulsa who fabricated the rifles used by many of the leading benchrest competitors in the Mid-Continent and Guild Coast Regions. Auston was himself one of the top benchrest shooters in those regions during his shooting career.
Editor’s Note: Both of Mr. Auston’s records were broken before the end of the 1955 shooting season, but Auston was the first to win the Sierra Prize. Interestingly, in setting his record, Austin broke the existing Agg record by L.E. Wilson of Cashmere, Washington — yes, the same L.E. Wilson that now makes dies.
Note the owner’s name, “S. Limbourne” was engraved on the bolt release (and trigger guard, see below).
Competition rifles don’t need to be beautiful, as long as they shoot. But who doesn’t like a spectacular figured-wood stock, particularly when it is combined with a superb custom action and a tack-driving barrel. This custom .284 Winchester F-Class Open division rig was crafted by gunsmith Thomas “Speedy” Gonzalez for competitive shooter Scott Limbourne. The handsome Bacote wood stock comes from Cerus Rifleworks, while the action is a polished Borden RBRP BRMXD. Two Brux 1:9″-twist barrels were chambered for the project, both finished at 32″. The stock is also fitted with a R.A.D. Recoil System. This rig has top-of-the-line hardware all around.
Action: Borden BRMXD – Polished
Rail: 20 MOA Polished
Chambering: .284 Winchester
Trigger: Jewell BR – Blueprinted
Barrel: (2x) Brux 32″ 1:9″ Twist
Stock: Cerus F-Open in Exhibition Grade Bacote
Recoil System: R.A.D. System
Extras: Carbon Fiber Tunnel Plate, Custom Engraving Work on Action, Trigger Guard, and Bolt Release.

The Lee Hand Press Kit comes complete with: Breech Lock Hand Press, Ram Primer fittings, Powder Funnel, Case Lube, and one Breech Lock Quick Change Bushing.
The Lee Breech Lock Hand Press is a useful addition to any reloader’s tool collection. This Hand Press allows you to resize brass or seat bullets while at the range or away from your loading room. No it won’t replace your Co-Ax or Rockchucker, but this is a handy piece of gear. And it’s very affordable. Midsouth sells the Lee Breech Lock Hand Press Kit, with everything shown above, for $64.52. Or you can buy just the Hand Press by itself for $49.91 at Amazon. That’s a great deal.
Lee Hand Press Quick-Change Die Functionality
This Lee Press includes the Breech Lock Quick-Change Die Feature, so you can instantly change dies with just a twist of the wrist. One Breech Lock Quick Change Bushing is included. The Breech Lock Hand Press is light and compact. It tips the scale at a mere 1 3/4 pounds and overall product length is 11.5″. Note: the maximum overall length cartridge the Lee Hand Press can accept is 3.650 inches.
While we don’t recommend the Hand Press for major full-length sizing chores, it does a good job seating bullets. This makes it a handy “field expedient” tool when doing load development at the range. For example you can experiment with seating depth by loading a batch of cartridges at home with the bullets deliberately seated long. Then, at the range, you can re-seat the bullets progressively shorter (in a series of rounds), until you find the optimal Cartridge OAL.
Lee’s Hand Press is also great for decapping operations. One verified buyer reports: “I mostly use it for decapping while watching TV, with a universal decapper die. Of course it is also useful for other operations. I wouldn’t love sizing large rifle cases with it, but if you’ve prepped your cases on a bigger press you could comfortably take it to the range for load development, one round at a time, working right there at the line instead of making a bunch of loads at home that you’ll have to disassemble later. It’s smaller and more lightweight than it looks[.]”
Using Hand Press to Load at the Range
To learn more about using the Lee Hand Press in the field with a compact scale, read Reloading Without a Bench on GunsAmerica.com. Author Christopher Mace explains: “whether you want a better way to do load development, the capability to reload out of your ‘bugout bag’, or you’re short of space but wanting to get into reloading, the Lee Loaders and the Lee Hand Press offer you some options.”
Here’s something all shooters need — a smartphone App that calculates bullet-hole group sizes from your own photos. The Ballistic-X App is simple to use. Take a photo of your target, set some values (such as bullet diameter and distance to target), then use the touchscreen to place circles around each hole. The App will calculate group size (in MOA or Mils), distance to point of aim, and provide all the info in an overlay. Then click “save” to record your group for posterity!
This App works well, is relatively easy to set-up, and costs just $7.99. It is available for both Android devices and iOS (Apple) devices. There are other ways to measure group sizes from target images, such as the excellent On-Target program, which we have used for years. However On-Target requires a software installation on a Windows platform desktop or laptop. Ballistic-X is a simple, easy-to-install App with versions for both Android and iOS (Apple) Mobile devices.
The Ballistic-X App has a relatively easy-to-use interface. Of course you can choose either MOA or Milrad group values, and Inch or Metric dimensions. There are various labeling options that provide useful info for Load Development. There is even an ATZ (Adjustment To Zero) feature for adjusting your turrets.
How to Use Ballistic-X App
1. Select Photo Source — Choose Camera to take new photo or get image from Photo Library.
2. Set Reference Values — Select Bullet Diameter and enter Distance to Target.
3. Establish Scale on Image — Mark two points on target photo to set scale. For example, if the target has a 1″-square grid lines, mark two points on grid for 1″ distance.
4. Mark Point Of Aim — Put the central X on the aim point.
5. Designate Shot Locations — Place the green circles around each shot.
6. Finalize Data Display — Position Overlay, select size/color options, and export file.
Android Options — Range Buddy FREE App
Along with Ballistic-X, there is another Mobile App, Range Buddy, that also measures shot groups. Range Buddy is currently offered for Android devices only. It is FREE, but has adverts. Range Buddy isn’t bad, but users complained about the program crashing, and there are compatibility issues with newer phones. We recommend you pay $7.99 and stick with Ballistic-X.
Hunting season opens soon around the country. What better way to prepare the mind and spirit for your hunting adventure than to read a classic hunting book? We’ve found ten of the best hunting books every written and provided links below. The list of authors is impressive, including Ernest Hemingway and Theodore Roosevelt.
Recommended Books about Hunting

If you ever shoot with electronic targets, ShotMarkers, or target cams, chances are you’ll spend lots of time looking at the screen of a tablet computer or iPad. These electronic devices are pretty amazing, but they have one major shortcoming when used outdoors — reflections from the highly-polished glass screen.
Well it turns out there is a simple, inexpensive solution to the problem of annoying tablet screen reflections. Just purchase a quality anti-reflective screen protector for your tablet, iPad, or smartphone and you will eliminate most annoying reflections and make your mobile device MUCH easier to use at the range.
Take a look at the two photos above. The first photo shows how annoying reflections can obscure the ShotMarker display on a tablet. The second shot shows how much easier it is to view the ShotMarker target image with an anti-reflective screen cover in place. BIG improvement!
Our friend Keith Glasscock recently added an anti-reflective screen protector to his iPad tablet and found that it works wonders. Keith recently reviewed the iCarez Matte Screen Protector for his Winning in the Wind YouTube Channel. These screen covers are available in a wide variety of sizes to fit most Apple iPhones and Apple iPads. These thin, matte screen protectors are quite affordable, with prices starting at just $6.95.
In addition, there are other brands of screen protectors for Android devices that work the same way. Again, you’ll find a variety of sizes. For example, Supershieldz now offers a 3-pack of matte screen covers for 10″ Samsung tablets for just $6.99 on Amazon
In the above video, Keith Glasscock explains the problem of screen reflections when using mobile devices for shot monitoring. Keith then describes his positive experience with the iCarez Matte screen cover installed on his personal iPad.
A good screen cover can eliminate this kind of harsh reflection on tablet screens:
Here’s something you don’t see every day — the inside of loaded cartridges, sliced halfway through. This lets you see how bullet core, jacket, cartridge case, powder, and primer all fit together. Give credit to the folks at FOG Ammunition for creating this interesting series of cut-through ammo images. We show four cartridges here: the .308 Winchester, 9mm Luger, 300 BLK, and .50 BMG. You’ll find two more (the .223 Remington and .45 ACP) at www.FogAmmo.com.
This .308 Winchester model took on a different approach by only cutting the brass case and displaying the full bullet, primer and powder load. A spec amount of powder was used to create the model powder form. An estimated 10% volume was added during the forming process, along with an undetermined amount of air pockets.
This bisection is a 9mm Luger Jacketed Hollow Point round with flake powder held together with super glue. After this self-defense round was cut by a trained professional the round was polished by hand. This might look like stick powder, but those are in fact flakes stacked up in cross-section. Designed in 1901 by Georg Luger, this popular cartridge is used by civilians, military, and law enforcement.
For this model of the .300 AAC Blackout (aka 300 BLK), a Dremel tool was used to create a pie cut within the bullet and brass case. A measured amount of power, roughly 65% of spec charge, was placed inside the case with super glue. This cartridge was originally optimized for subsonic use with a suppressor, so the amount of powder used is small relative to the nominal case capacity. That leaves more room for the relatively large .30-caliber bullet.
Last but definitely not least is the .50 Caliber BMG round (aka .50 Browning Machine Gun). Famed for its wartime use in the M2 Machine gun, the .50 BMG round is also used in civilian Long Range competitions. A typical .50 BMG cartridge holds over 225 grains of powder. That’s almost ten times the amount in a 5.56×45 NATO Round! To demonstrate the size of the .50 BMG, check out that .223 Rem for comparison.
Forum member Peebles24 showcased his cool flame-paint-job .22 LR benchrest rifle against a scenic, snowy background (never too cold to shoot right?). “I had a new rifle built this past fall by Mark Penrod at Penrod Precision. Stiller 2500X action, Shilen ratchet barrel, Jewell trigger, McMillan stock, Harrell’s tuner, Sightron SIII 10-50×60mm glass. I’m shooting it off my Arnold Machine one-piece rest made locally by Cliff Arnold. I visited the Lapua Testing Center East and got a case of Midas+.” For ammo testing results, click photo at right.
Forum member JAS-AS purchased a .22 Magnum CZ which he revived as a training rig with a new stock. He posted: “I use a CZ457 in .22 Magnum mainly as a trainer — bipod and rear bag kind of stuff. It has evolved over the last year or so. Next change will be a Lilja barrel. This because it can shoot brilliantly (at times) but not consistently. And accuracy degrades as it gets minimally dirty. Also, it doesn’t like 40gr rounds — the groups open up to 1.5 MOA. It’s at its best with 30 and 35 grain rounds running at up to 2250 fps. I believe that to be a twist-rate issue.”
