Tank with preset velocity @ 850, 2 carrier, 2 shims, short spring. Moderate leak out the back. Bolt acts as though it is hitting a ball (cycles half way), then resets. No way to chrono and see velocity. Any suggestions?

turn down velocity, or try to go down a carrier. and add some oil -
As it turns out
it's a bad o-ring in the QD. However, the marker shoots only part of the time (one or two good shots, then a couple of shots that feels like LX is engaging).

Ran down to the local PB shop to see about the o-ring. Had Randy chrono it at the same time. You were right, I was sitting at 190. Turned it up to 280 and things are sweet. Thanks!!!
