This is a 4-gauge, or 4-bore in the U.K., black powder shotgun that launches five ounces of lead in whatever general direction you really don’t like all that much.
I like watching the people’s shoulders fly around separately before the recoil wave reaches their torso. This is because a 4-gauge shotgun barrel has an inner diameter of 1.053 inches. Yeah.
Would have like to see some targets, though. Still, check out more at The Great Aardvark’s House of Fun, a YouTube Channel.
