Glad it worked out for ya?

Yea, sometimes ammo can be the Culprit and all but I'd advise ya run a bunch of different ammo into it past 500 rounds and see if it's bug free! Sounds like ya get it right, but I hope for the best for ya! Plus, it's fun doing that testing anyhow, right? Otrher than paying for the ammo?
