Ke= 1/2 mv^2 soo 1lb/32.2 (200ft/s)^2/2 = 621 ft lbs right?

ok ok so its not really an air rifle. It doesn't target shoot terrible well (actually it does, just requires a lot of calculation before the shot) and it takes ten minutes to reload. but hey. Sacrifices must be made sometimes.... like a twenty pound trigger. not exactly match grade...
