Im new to hunting, but not to rifles. I served eight years in the Army, so I know my way around those types of rifles. Never hunted before. Im planning a hunting trip for next season, with other experienced hunters, and want to go for black bear. What caliber of rifle is good for that? Also, what type of ammo? Im not into overkill, I want the hide and the meat, and have no desire to call in a missle strike to get it. Advice, please.
