I just picked a Saxby Palmer Ensign, with the pump and plastic cartridges, but no manual. At first I could not get the uncharged cartridges to completely chamber, until I removed a small metal "thing" under the screw on cap. I tried pumping the cartridge up with 3 pumps, but was unable to get them to hold air. Anybody have a manual or know where I can find one. Even the procedure to charge the cartridge correctly would help. The one I tried cracked the shell when I pulled the trigger.
