Here's a question, lets say you are shooting a 140 grain ttsx 7mm and getting complete pass thrus on game what would be the advantage to going to a larger bullet of the same diameter and brand(ttsx)? Would they kill any better? Or is the wound channel the same size from a 140 ttsx and a 160 grain ttsx if they both pass thru. Im not asking about ballistic coefficient and down range flight just thinking just wound channel. I also realize a heavier bullet will penetrate further but if they both go thru is there any advantage one way or another?
