I like to shoot a bunch of 5 shot groups at targets I print on regular printer paper. After I shoot a bunch of groups, I can stack up the paper so the targets all line up, hold it to a strong light, and I can see simulated 10, 15, or even 20 shot groups. One day I was testing three different hand loads, with quite varying powder charges, and the stacked groups were within a 2" circle at 100 yards. That made me feel really good; not only were the groups small, but the rifle was very forgiving of variations in the ammo. (Of course, the bullets and powder type were the same. No way it would put a 120 gr bullet to the same spot as a 140 gr.)
One other thing: if someone claims a certain size 3 shot group, that should be only three shots at the target. It's not shooting 5 shots and measuring the best three. If the best three are shots 1,3, and 5, that's cheating.
