Doug have you ever filled a 72 c.i. tank with a hand pump? At 3000 p.s.i. how many pump strokes would you need. Doug you must be one determined shooter. I tried to fill a 22 c.i. tank and I thought I would drop dead. lol Way to hard. Benson.
With the Discovery pump, it took about 1400-1450 pump strokes from empty. About 400-450 strokes to get from 2000psi to 3000psi. And yes, it does take quite a bit of time and effort. Doug is indeed determined.
