I have a WASR-3 from Century.
It was a problem gun from the start, but after some additional "tuning," it became pretty reliable.
After 600-800 rounds, it's starting to have a weird mystery jam:
Rifle fails to eject, rim slips over cartridge, and it cycles a new shell into the casehead of the unextracted shell. Often times the spent shell is halfway out of the chamber.
Notes:
I'm wondering if the bolt surface's peening was hanging up the action just long enough to build chamber pressure and push the case out so badly that it's sticking to the walls? Maybe this disrupts the cycle and the rifle's timing is off?
I'm not tearing rims off or caseheads or anything.
The chamber is difficult to clean in an AK. What do you use to get in there?
Could the head-spacing be off on the rifle somehow? Would this cause that kind of problem?

Notes:
- Brass is factory loaded Remington 55 gr. FMJ, a load this rifle has fired many times reliably.
- Happens with all mags used reliably previously.
- Shell's base is distorted somewhat on one side.
- Spent shells are difficult to re-insert into chamber, and impossible to remove without a tool under the rim.
- Spent .223 shells from other rifles slide into chamber and extract under finger pressure.
- NOTICED: A small burr on backside of bolt which seemed to be hanging up action somewhat. Filed down burrs, inspected mating area on carrier, no burrs seen there. Action now smooth.
