Been using the .308 for years in several different rifles. All very accurate. No problems deer hunting either. One shot, one deer - every time. Never had one run off much after the hit either. Good for elk & moose too if you use the heavier bullets, like 180gr.
Recommend Nosler or Trophy Bonded for use on the larger critters. As for black bear, I'd again go with 180gr., or maybe use the 165gr.. Of course, 150gr deer load will take most black bear cleanly, but I'd just like a little more bullet weight for those larger black
bears.
