I bought 900 rounds of Wolf and have the same issue. The stuff does not extract. Luckily one of my guns can handle it. I know some people use this stuff without problem but It's a crap shoot. I have a new Micro Compact that I was able to crank through 100 rounds in one setting with out a failure (Winchester FMJ). I then loaded my Wolf into it and I couldn't even get one round through with a FTE. It was digital so I know it's the ammo. If you have a nice loose chamber your probably fine. I'm going to try S&B next. It seems most are satisfied with it.
