For the first time ever, I had to admit defeat in my stubborn insistance that wolf should work in any gun I own.
My stg just won't work for too many rounds before one finally gets stuck in the chamber and the extractor rips loose from it. I can't even say that it's an underpower issue, because after losing some power ripping off of the stuck round, it usually still has enough to cycle back and strip the next round off, jamming it up the ass of the stuck one.
I tried a couple of times to *polish* the chamber up, but the problem persistantly repeats itself.
It's not an issue of expansion differences between brass and steel, the chamber gets gummed up.
I admit defeat and will just be sure to use brass cased ammo ,in this gun anyway, from here on out.
I'm just a plinker, no tacticool training or serious marksmanship,just fun, and wolf has done an exemplary job in all of my other firearms....but not in this.
