For example a 45/3000 should get you over 450, and a 68 tank should get you over 680. So if you get a 4500psi tank you will get more shots. I use a 45/4500 and I get anywhere from 700-850 shots. If you are used to a 68ci tank then get a Crossfire 68/4500 and you will get thousands of shots off of a full fill.
Correct. The general rule of thumb is that 68/3000=68x10, and 68/4500=68x15.
