My intial sight in was with 20gr XTPs at 25 just shy (low) of bull = +3areaat 100 if i recall correctly(sorry been awhile and haven't shot at 25 since that day eitheron the range). Great little gun but as meantioned highly suspect of wind drift, as such I have gone to the 20 grs even though they give up trajectory and slightly larger groups they are more shootable here on the prairie's where wind is a staple!

Good luck
