1" CTC with .22 pellet gun outdoors is very good. I've shot some 21mm groups with my Scorpion and JSB Kings but .25 has better BC than a .22. Doing sub 1" groups at 100M with a bullet shooter means I can expect 2-3" groups at 200M if I read the wind right. After all the BC of a 257420BT bullet is about 0.16 while .22 pellets have only about 0.03 BC, that has a HUGE impact on wind drift. If you are interested in those things Bob Sterne wrote a rather eye opening article about the effects of the BC
