If you're getting less then you've probably got the silver transfer port fitted or your bleeding air each shot from around the breech area. Hopefully not trying to teach you how to suck eggs
....there should be a small blast of air from the top of the breech (where the small black stabiliser latch is) but not from the bottom. if there is then a new breech or transfer port o ring is required, a shim might be required under the transfer port or the closing of the barrel to the breech isn't positive enough.
My steyr has had a new transfer port, 2 breech seals (the second after the first blew out when the breech wasn't fully closed) and the reg adjusted. After adjusting the stabiliser I seem to be using even more air. You mention the closing of the barrel to the breech not being positive enough as a cause for excessive air use.... I am missing the foam spacer in the breech. A shallower replacement has been made and put in place. Would the lack of this part or shallower replacement cause air leakage at this point?
