wow, those numbers seem really unusually high for a mostly stock 1322. Actually, almost unbelievably high. My 1322 is highly modified, with 18" barrel, brass flat top piston and matching brass valve, machined exhaust port, etc, , and it only makes 9fpe with 10 pumps and 14.3 gr. pellets. Not that I'm suggesting that you aren't being honest, but if you are really getting those velocity numbers with 10 pumps and those heavy pellets, I wouldn't ever do any further modification to that gun ever, and if it also shoots accurately, you hit the mega 1322 lottery.
