While my AR is not, my primary HD weapon, I'd still like to keep a mag or two on hand of good defensive ammo on hand. (may also end up using it on coyotes at some point) The general consensus seems to be that the heavier bullets are the most effective fight stoppers. At this point I'm shooting 55g loads because its what is most readily available in my area. My question is how large of a POI varaition is there once one start stepping up to the heavier bullet weights? I'm sure at nominal SD ranges, its not s concern, but I'm OCD about things...
