Shooting a semi-auto .308 or 6.5 Creedmoor AR for hunting can be done and done well. An AR example below. I prefer a bolt action but hey…this works. A great wild boar rifle too, where southern and western farmers are overrun with them.
The semi-auto AR 10 platform for hunting is a do-it-all rifle for protection, hunting game, and predators.
I personally prefer a bolt action rifle but in the right hands, this rifle works. In brown bear country, this reliable rifle gives comfort to folks living off-grid as does a 44 mag pistol as a side arm.
Ranchers use this tool like they use a hammer. If you have a nail, then the hammer is the right tool. If you have a brown bear sniffing in your direction, having a large clip of .308 cartridges at the ready can be comforting. Or live in Texas or Florida where they are overrun with pigs.
I am no expert on AR Rifles for hunting big game but I did find a great article on the web by Outdoor Life.
Check it out, they are fun to shoot.
