okay this one stumps me.....it sounds like it could be bolt-stick but???
on slow (around 3bps tops) she fires fine - whick lets face it ain't much use.
open up the throttle with eyes on and she goes - BANG BANG BANG PHTTT - end of...
turn eyes off and its more like:
BANG BANG BANG PFTT PFTT BANG BANG BANG BANG BANG PFTT PFTTT PFTT BANG...you get the picture.
she ran like a real dream for around half dozen pods and a hopper on a fresh procell - out shooting my old ego7 on semi
then the problem arrived - changed battery - same problem continued
thoughts?
Have you checked out the oring inside the breach (just behind the feedneck)?
If that one isnt popping out properly it can cause that problem.
What pressures/inserts are you runing?
How does it perform at... say 350fps?
