Hi guys got a proto rail recently it had barely been used but i changed all the O rings because the chrono was all over the place, now its started to do this thing where it fires then starts to lose power where the bolt will move but not with enough force or the sound that goes with it, any ideas why it could be doing this? is it worth playing with the dwell settings to try sort this? Also as far as lubrication goes im using some greese i got with it or is it best to get the dye lube?
Thanks in advance
