For deer hunting, .308 Winchester and .30-06 Springfield are classic choices. 6.5 Creedmoor has become extremely popular for its flat trajectory and low recoil. For elk and larger game, consider .300 Win Mag.
Should I buy a bolt-action or semi-auto hunting rifle?
Bolt-action rifles are generally more accurate and reliable for hunting. Semi-auto rifles like the Browning BAR offer faster follow-up shots. Most hunters prefer bolt-action for precision.
