When my dad was in his 20's when he put four 12 gauge slugs into a buck that was in full rut. The thing just kept going after the first, second, and third shots. All the shots were in the chest, the forth one went right through the shoulder, keeping him from going any further. My dad still has all four slugs that he dug out of the ribs and shoulders. It amazes me what this animals are capable off.
