Greataardvark is a channel specializing in Slow motion capture, ranging from Guns to wildlife, and today they have something even more special. A Blackpowder 4 Gauge Shotgun Has A Huge Explosion And Surprisingly Little Recoil. An English 4 bore is the equivalent of a US 4 gauge. Bore is the equal to a Ball of Lead, in which here you get 4. This 4 Gauge was made in 1979 and is Blackpowder, which has a slower burn than Nitro and therefore has less of a kickback in the recoil. Pretty much, anything you hit within 20 Meters is going to be turned into Swiss Cheese.
