Your such a stud slugman with that 20lb sluggun.

As far as the rest, I have a few slugguns. If its a pump and around 7 to 8lbs like 870' s and mossbergs, yea, its goin to give ya a whallop. More than a 338RUM. But I got me a browning gold semi. That really takes the bite out of them. With the Semi action in conjuction with a good recoil pad that comes on a gold, it tames it down to a 300Win mag or less with 3" shells.
