Rimfire Excellence — Bartlein-Barreled .22 LR Tactical Tackdriver

Brian, a gunsmith at GA Precision, built this rimfire rig with GAP colleague Anthony Soukup.

On his Facebook page, Tactical competitor Bryan Sikes posted a photo of a rimfire rig we really liked. Brian works at GA Precision. He and fellow GAP gunsmith Anthony Soukup built this rifle. With a modified Rem 40X action, Manners stock, Bartlein barrel, and Mack Brothers suppressor, this rig has top-quality components stem to stern. And Bryan tells us this rifle performs as good as it looks: “This is the baddest little .22 LR trainer ever. I’m stoked about it. With the barrel length and can, it’s the exact length of my regular comp rigs.” With length, balance, and ergonomics near identical to Bryan’s centerfire competition rifles, this 40X is a superb training tool.

• Modified Remington 40X Action
• Calvin Elite Trigger
• Bartlein #5 22″ Barrel
• Mack Brothers Vapor Suppressor

• Bedded Manners T4-A Stock
• Defiance Embedded Front Rail (EFR)
• Harris Swivel Bipod with Handle
• Bushnell DMR2 Scope w/ G3 Reticle

Many readers wanted to know about the bottom metal and the detachable box magazine. Bryan Sike reveals: “The magazine setup is designed specifically to replicate my actual competition rifles. The bottom metal is for use with AI magazines and uses a standard M5 type inlet just like any centerfire completion rifle. In this case with the .22LR, Mike Bush designed a high reliability rimfire magazine using the same outside dimensions as an AI magazine. This rifle was built no different from any other. The action was modified and trued, barreled, fully bedded, etc. using ALL components common to centerfire match rifles.” The Rem 40X action was modified by Modacam Custom Rifles to work as a repeater with box mags.

Bryan adds that a new rimfire action is in the works: “My preference is modified Remington 40X actions and the [Vudoo Gunworks V-22 Action]. Both of which are TRUE repeaters and don’t feed from a Savage magazine. This rifle feels nothing like a .22 LR and that was the whole point.”

Why You Need a .22 LR Tactical Cross-Trainer

Many guys who shoot long-range tactical matches practice with .22 LR rifles of similar configuration. Rimfire ammo is way more affordable than centerfire, you do not need a big range facility, and shooting rimfire saves wear and tear on your centerfire rifle. Further, for learning how to read the wind, there really is no better training tool than a .22 LR, even as close as 50 yards.

Our Friend “DesertFrog”, who shoots tactical matches in Southern California, explains: “I used to shoot an average of 200 rounds of .308 Match ammo a month for training (50 per weekend). These days I shoot maybe an average of 50 rounds of .308 Win per month and probably around 600 rounds of .22 LR. Using mainly the .22 LR for practice did NOT hurt my standings in actual competitions. I shot my .308 just as well in matches, but saved the cost of hundreds of rounds of .308. If I didn’t reload and was still buying boxes of Federal Gold Medal Match .308 Win [at $1.75/round], this would be a savings of [$262.50 per month on the centerfire ammo (150 rounds).]” Money saved is money earned.

Bullet Jacket Scratches Can Affect BC and Long Range Accuracy

Here’s a smart tip from Bryan Litz, explaining how damage to a bullet jacket can harm the projectile’s Ballistic Coefficient (BC). This tip is posted on Bryan’s new Bryan Litz Ballistics Facebook page. We recommend you subscribe to that page to access Bryan’s latest informative posts.

Bryan notes: “If the case mouth scratches the bullet when you seat it, the damage can cause the BC to be inconsistent, which shows up as vertical dispersion at long range.”

We see this sometimes when running Doppler Radar for competitors at Applied Ballistics Mobile Lab events. If someone is shooting a bullet that typically has a very consistent BC (1% or less) but they’re seeing a higher BC variation, it can be due to the bullets being damaged in the loading process.”

The lead photo above shows the badly-scratched jacket of a bullet seated in a rough-mouthed case. To prevent such jacket damage, one should chamfer, deburr, and smooth case mouths after trimming.

Below is a recorded Doppler radar result showing excessive BC variation. Such variation can increase vertical dispersion at long range. This can result in larger group sizes and lower scores.
