So I took my Mummy out today for the first time after buying it off Ebay. At first, all it would do is sputter and not fire. A tech there fixed that and got it to fire. However, the velocity is all over the place. I took it into a game thinking it wouldn't be that bad, and at first it thr balls were going about half a foot before dropping to the ground. Then, it picked up and started kicking a lot. I wasn't sure if that was normal, but I continued playing normally. When I went to chrono it to see what was up, it was shooting at 380. Felt really bad for the people I shot. Here's the sequence(keep in mind that I was adjusting it gradually throughout this until the very last shot): 380-360-340-300-290-215-205-400. If it means anything, every turn or two the reg would start leaking out of the bead bearing(not sure if that's the word, but where you adjust the HPR psi), then I would have to degas it then gas it up again, which would fix it. Already tried a new battery as well. Shooting Valken Infinity paint. High pressure output on my 47/3000 Empire tank. The bolt and HPR were lubed before all this, using TechT Gun Sav. The tech put some other brand of lube on a few orings in the bolt, it appeared to be Lurker, but I'm no expert on lube. Not sure about the LPR, since I haven't been able to take it apart.
Any help is appreciated.
Note: I won't be able to test anything until I get home tonorrow from vacation.
