I hunt with a .308 myself. It’s a great round and definitely has a place when range needs are greater. The US Army and Marines brought back their M-14s for use in Afghanistan due to the much greater ranges encountered in that area, semi-automatic only btw. But, I’m not and you’re not shooting such rifles on full automatic unless you’ve got a class 3 license. And the issue I was highlighting was that a 7 lb 7.62 rifle isn’t controllable on full automatic. That’s just physics.
