So it was either the hpr shrader, noid cleaning, blast guide polishing, or the changing of every single oring (other then the few that weren't in the manual...) that fixed it. Really don't care at this point Dwell 6, started hpr @ 200 and lpr @ 80. that gave me 260. then increased hpr a little up to about 275 fps and then it started to drop velocity so bumped lpr up a tiny bit, then a little more hpr and its golden. consistent too, +- 5 fps. Not sure what pressures i ended up with and i really don't want to look.... thanks for the help guys. I contacted xeese about the missing oring sizes maybe he or i'll make a seperate thread once everything is figured out so when people need a COMPLETE oring kit they know what sizes to order.
