Is anyone using a small tank like the Benji or others in the 60 cu. in. size? How many fills are you getting per 3K filled tank when filling a discovery to 2K?
You've left an important factor out, what pressure do you run the gun to before you fill? I run mine to about 1400, that's what I used to figure.
60 CI tanks at 3000 psi (200 bar) hold 12,000 CI of gas, about seven CF. Plug the 7 into the AH fill calculator:
Entering 124 cc for the gun tank (what I recall), and I get 13 full fills (and some patials). I have a friend that estimated about that with his.
