First test was a standard nerf dart fire under a pressure of 80 psi. Impressively made it through both sides of a Weetabix box . Second test was a potato pumped up to 110psi which is about the max for my pump. Holy S**T is all I can say. With the nice snug fit of an inch long cylinder of potato rammed down the barrel the power was unbelievable. Tomorrow me and mini me will be conducting further daylight testing
Chrono results please Mike!
