damn damn damn, just tried it over a crono, using remote line got it to 280 fps +/- 5 on air. tried a 12 gram. 10 shots - first 330, then an almost straight line drop to 220 by the tenth, I don't want to use a remote so now I've got to figure our a way to mount the asa at an angle and beef up the support for it to take a 13ci tank..... where's my hacksaw? knuckles prepare to bleed....
