now i finally got the macro for my Latest build and i thought id try it with the classic valve as thats what i am going to run it with, anyway i only had a little air in my lp bottle (about 500psi) and it seemed to shot 14bps fine before i run out of air going to re-try with a full bottle and a chrono as im not sure of the shoot down effect it will have.

Now i know a classic valve can shout 15-16bps with 850 input but does any one have any thoughts on the LP side of things, only reason i ask is it saves me swapping out shims in my reg evertime i swap guns
