Never measured any groups, but at 100, I can hit a 20 oz coke bottle all day long standing with my .22.
At 200, I have no problem hitting the bull 10 out of 10 times while shooting highpower matches with my Garand standing. Bull is approximately 12" in diameter. Shooting prone, at the same distance, my groups are probably 1/2 the size. Its hard to judge, as I'm shooting a 2-2.5 moa rifle nearly to its potential from prone. I'm still learning.
