Are you guys shooting 5 shot groups, or the more relevant 10 shot groups?
I used to shoot 5 shot groups, but recently started running 10 round groups when possible. The increased round count in the larger group is far more likely to display the true full range of variances in the barrel/ammo combination. If you really want to know just how far any given round from a particular type of ammo will deviate from POA you need to shoot groups with higher round counts.
