Hey, let us know how it works out, I think that may be a sweet setup. I bet you could fine tune the air consumption by adjusting the hammer spring tnsion while shooting over a chrony. Just increase the powerwheel till you reach max velocity, then stop and maybe turn back half a turn. Shouldn't be a ton of hammer bounce, but if you could get your hands on a lightenned hammer it may help some also. If you haven't already get your hands on some 90 dura breach o-rings, they make a big difference in consistancy.
