What do you mean exactly by shot terribly?It was expensive as hell and shot terribly in my Ruger 10/22 target.
What do you mean exactly by shot terribly?
separated into lots using a case thickness gauge.
Did you clean and re-foul betwen ammos? Since .22s use different lubes, if you shoot a 10 shot group with your normal ammo, then with different ammo, the second ammo will NOT perform to its max.
The serious guys shoot 50 - 100 rounds of the new stuff before shooting for groups. Or clean the barrel and shoot 20 rounds to "season" the barrel with the new lube, then shoot for group.
