Response to MULTI SHOT 392....

stroke length. Look at a benjamin cartridge valve, and imagine much of that brass removed..you'll get an idea of what I've done. It's based on James P's skeleton valve concept. It definitely helps the pump effort and efficiency, and allows a second shot within 20 fps of the first..with no pumping between those two shots.

Tell me about the two shot shuttle for the integrabase..THAT'S a great idea!
