Reply To: Boss regulated 500 Whos done it?
62 ft/lbs is a bit optimistic though, I got that with my .25 converted Boss with huge 7mm transfer port.
Did a couple of Royales as well, but my experience tells me a Royale 500 gives about 850fps with a reg pressure of 160bar (about 54.5 ft/lbs.)
Which is a nice speed for a ST barrel b.t.w.
(EDIT: I’m talking about the models with power adjuster;-)
