Hey guys anyone have the 7.62x39  ta bolt cause 2 little dents on the case where the extractor is?

When the chamber is empty the bolt moves easily and smooth, the first round I loaded didn't seat fully which happend 3 out of the 5 shots I took before the bolt got stuck semi closed. When I finally got it apart I saw the round was stuck on the bolt, and when I took the round off the bolt I noticed the 2 indents where the extractor contacts the case.

What is the cause and possible fix?

the bolt also doesn't lock back but I think i figured that out. Gas block was a little crooked and I had the M16 bcg and a st-t2 buffer, I swapped out for a standard one. Just need to test fire now.

I had this issue, both with the TA bolt as well as every 7.62x39 bolt I bought.  

I was on the verge of giving up but then I bought the LMT bolt and now it works properly.

Ok thanks ill be looking into an LMT bolt then
