I wouldn’t go over 100 yards for deer sized game. And the closer the better. I shoot Lehighs suppressed in mine for hunting. I think they’re about 190 grains.
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.

Those Lehigh's are 194gr.  
Did you stock up on them when TargetSportsUSA was blowing out the original 4 pedal design (Apex loaded) for dirt cheap? They had dropped $0.70/rnd with free shipping at one point.  The normal Lehigh/Wilson Combat loaded versions are like $3.50 a pop.
