This is a video of Slow Mo Guys Gav and Dan hanging out with Scott of Kentucky Ballistics and firing his 950 JDJ Fat Mac, the largest sporting rifle in the world (and 1 of only 3 produced). The gun weighs 50 pounds, produces 300 pounds of recoil, and fires 0.95″ diameter projectiles. Damn! The look on Dan’s face after firing it for the first time tells me everything I need to know. Mostly, that yes, it is possible to poop your pants and get an erection simultaneously.
