Well guess I can fart around with it to my hearts content then. Hmmm, maybe groove the stock bolt for an o-ring behind the port, that way any air escaping will go down the barrel versus back. Try a new bolt made out of whatever plastic (I am open for suggestions here I can get ahold of just about every kind of engineering plastic there is), looks like instead of a heavier hammer I might try making the stock one lighter (bore some holes in it).
UPDATE: If anyone cares the bolt is going to be made out of carbon filled PEEK bearing material, low wear properties and good dimensional stability.
