Given the accuracy of Norma USA 22 rimfire ammo, both TAC-22 and Match-22, I believe this October’s squirrel hunts will be more rewarding than ever. The satisfaction of making clean, deadly shots while barely disturbing the world around me is half my reward. I don’t need hearing protection, so I’m free to listen as well as watch autumn's splendor coming down. In addition, I noticed that the spent casings were fairly clean compared to standard velocity spent casings. The report of a 22 rimfire rifle is so slight that the woods return to normal within a minute or less if I minimize movement. Primer Location: Rimfire Muzzle Energy: 102 ft-lbs Lot Number Tested: 27555/705775 A few other minor observations I was able to make is that the smell of the burnt powder was quite unlike any other rimfire cartridge I had fired. My goal is to pick them off one by one, head shots only, until I have enough for a hearty stew. I might stalk a bit and call a bit, but this is my chance to relax and soak up the most glorious season. One of my most satisfying annual hunts is a quiet wait for tree squirrels in an October hardwood forest. That’s more than enough to terminate cottontails and various squirrels with head or chest hits. Stepping down to 1,000 fps drops 22 long rifle muzzle energy to about 100 f-p or slightly less. A couple of weeks ago Jim Barrett reviewed the. (not Unique, just unique) Total metal jacket (TMJ) bullets in centerfire and fully copper plated in rimfire. Compare that to the 1,150 f-p muzzle energy from a 40-grain 223 Remington load and you’ll begin to appreciate the difference. Federal did say that all of these loadings are using unique propellant blends. Five of the rounds gave results that I thought were fairly typical so there were no. ![]() ![]() I tested CCI Velocitor, CCI SGB, Federal Hunter Match, Eley High velocity hollowpoint, Eley Subsonic Hollow Point (SSHP), and Eley Club. I was chronying six different rounds of 22lr in my new S&W 617-6 4' barrel. A 40-grain, 22 caliber lead bullet at 1,400 fps is considered hyper velocity for a 22 rimfire, yet it only kicks out about 180 foot-pounds of energy at the muzzle. Impressive Eley Subsonic Hollowpoint statistics. In 22 rimfires I don’t worry about kinetic energy because there isn’t much of it in even the fastest 22 LR load.
