If anything the aerotips are probably going to group even better than the hollowpoints because they are more aerodynamic. The aerotips are supposed to punch through a deer better also. :wink:
I used 225 powerbelt hollowpoints in my Encore .45 barrel (now sold) and killed four deer with them, but didn't like the no-pass through performance. The deer were dead, but I like a good blood trail and only one deer out of four had a hole on both sides.
Just my opinion, but I wouldn't go less than 225 grain bullets on a deer unless you are a good tracker or hunt in a open area where you can watch them fall.....
