Only problem with trying a hyper velocity shoulder shot with the 158 is what if it doesn't get past the bone lol if you had back up id imagine one going that fast would knock a small deer over long enough for someone to put the down... As for me I was worried about the 158 making it through a large ohio bucks shoulder at any velocity... I hunt a 40 ish acre lot surrounded by some kind of agriculture for a few miles on every side... Yeah 300 pound deer are the rule not the exception... I even feel iffy with a 180 at 2000 on that large a deer but im going to find out this weekend my 357 mag barrel is getting a lift to maximum and I can already get 1800 out of a 180 so we will see....
