Someone is ornery ha
308 has killed many, many animals. It's just fine for deer.
You do realize you're supposed to aim behind the front shoulder, not the rear legs, right?
Try shooting past 200 yards then talk. I know a .22 can kill a deer but I'll never depend on a .308 again! Just my personal (hated) experience but to each his own.
