I like my 45 cal. 150 grains of triple 7 and 195 grain powerbelt does the trick. I love how flat it shoots, the only concern is rarely get a passthru with it, unless I am shooting long distance. It is a double edged sword for me, every deer I shoot with it dies, the trauma from the powerbelts is unreal especially when they literally blow up on impact, I have never seen such wicked nasty holes. Then again it seems like it would be better to have a pass thru. I know if I shot barnes or knight red hots they would blow right through every deer, but I guess don't fix what isnt broken.
