A couple of months ago, I decided to test several different brands of .22 LR in my Ruger American Rimfire Compact. I tested from a Caldwell rest, with a toe bag, at the NRA Headquarters (indoor) range in Fairfax, VA, at 50 yards. The scope is a Vortex Crossfire II 2-7x32 Rimfire. Groups were scanned and analyzed using OnTarget PC. Here are the results. Numbers are for legitmate 5-shot groups (NO excluded flyers!) at 50 yards, in MOA (divide by approximately half to get inches): Aguila Super Extra: best 0.799; average 1.712; worst 2.443 Eley Tenex: best 0.983; average 1.166; worst 1.481 SK Rifle Match: best 1.268; average 2.01; worst 3.416 Federal Hunter Match: best .918; average 2.117; worst 4.7 Not surprisingly, Eley Tenex far out-performed the others. But it's also $24.49 for a box of 50, compared to $6.49 for Federal Hunter Match, $9.99 for SK Rifle Match, and $2.99 for Aguila Super Extra. Heck, the Tenex is almost ten times the price of the Aguila! The best value, by far, is the Aguila Super Extra, which is what I'll be stocking up on. I'm including a picture of my best group using Aguila Super Extra 40 grain copper plated: 0.418-inch, 0.799 MOA group. That's sub-MOA accuracy from an unmodified out-of-the-box $300 rifle and $130 scope using non-match ammo.
