OK it is easy to find the psi of co2 at 75 degrees... it is 905. Can anyone help me out with the psi generated at 10 pumps with a standard 1377? And/or even modified ones? I would like to do more barrel testing with air and would like to approximate the pump gun performance without using the pump gun LOL . 8)
