DM is correct--

With Bears the FIRST SHOT must "break 'em down" and stop the attack.This should be into the vital chest/shoulder region depending on the angle presented.Subsequent shots should be heart/lung with a finisher to the CNS if needed.

Bears are incredibly quick when they choose to be.They are heavy boned and can be tough to kill.

Best Gun? Personal choice but bear means "BIG BORE RIFLE "to me.
