Here's my Condor I got from R&L airguns. 308 caliber and I've put a 68/4500 paintball tank on it with a EtacHPA.
So far I've managed to get 40 shots on low with 52 grain bullet staying between 840fps-860fps-840fps for 20 shots and turning the power wheel up to get a total of 40 shots and saying between 840 and 860fps on a 2700psi fill down to 1800psi.
On high power the 52 grain is making 122fpe for 24 shots and a 124grain is making 183fpe for 19 shots.
I'm still in the process of tuning it and finding the right combination of top hat setting and power wheel setting.
I'm really enjoying this gun!!
