Shooting for POA/POI from only 5 yards isn't much of a test.
Why is that? I like to test one thing at a time. On this outing I was testing my ammo. Are you saying the results would have been different had I shot at 10 or 15 yards? It seems to me the groups would have been larger but I can't see why the end result would have changed.
NV',
Slow fire testing groups (at five yards) should be no larger than a quarter. If they are, we are a long ways from determining which HP your pistol prefers.
I'm not saying this to be an a-hole. But it would appear bulk FMJ is more necessary than group testing.
