[postal] I'll find out which cheap is the bad cheap.....
I just got my new GP-WASR (new mfg AK-47 semi-auto - from Romania) Thurs night. I'll see how much it likes the wolf ammo.
My SKS still has cosmo plugging it up. I had it out shooting in 40* temp and it had more problems then.

I'm wondering if there is a burr or nick in the extractor tip. Have your pulled it out and looked at it? You mat hit a gun show and see if you can get a bolt for it and change that out. They can't be very expensive. I'm going to the Tanner Gun Show today, I'll see what they cost. If I can get it really cheap, I'll grab one and let you try it. I always need spare parts.
