what is the chamber flute?If you have not already. Make sure the chamber flutes are good and clean.
Also, Give the extractor on the bolt-head a wiggle. If you can move it at all,
time for a new extractor spring.
is there a certain range of serial numbers that have this problem?There were a lot of PTRs that had problems with the flutes in the chamber not being quite up to HK spec. They are possibly very slight accuracy advantages to the tight chamber with reduced flutes but they can be very picky about ammo. Presumably the previous owner discovered this and sold the rifle for that reason.
You can either have it rebarreled or have the flutes re-cut.... If you do some searches there is significant discussion of this on a more HK centric forum.
PTR has just come out with a "GI" spec rifle that has barrel cut to HK spec with a lighter profle that will handle any ammo....... Some have interpreted this as "fixing" the problem without admiting there was a problem.

I think I mean failure to eject. When I shoot the gun, the bolt hardly moves back at all, and the spent casing is still stuck in the chamber.You write in your first post you are having 'fte' issues. Gotta clarify for me.
Do you mean FT-Eject or FT-Extract? Also as mentioned in an earier post,
read up on the RDB design.

I was using magtech ammo. And after reading a bunch of posts on the internet, it seems i'm not the only one having problems with magtech ammo in a ptr 91I would still bet is was more the ammo than it being clean/not clean.
What kind of ammo did you try originally?
The cool thing is that even though milsurp may not work well for you the cheap stuff like Tula and Wolf .308 should.
