I have a Romanian Tokarev that has a tight chamber. I have tried a few fixes and they seemed to help, but I'm still having issues. Rounds will periodically (at least 2-3 per magazine unless hell froze over that day) enter the chamber but will not fully seat. They stop just a bit short. Maybe 1/8" at most. They also get jammed in there pretty good. They dang sure won't go forward, and you gotta muscle it a bit to get them to eject. The bore is .314" IIRC, I do not have a chamber cast unfortunately (need to buy some chamber casting metal). The bullets I'm using are the 90gr .309" XTPs. I have thought of using .308" FMJ bullets, but doubt that would solve this problem. (BTW, despite the much larger bore, the .309"s actually shoot pretty well).
Here's what I've tried.
I aggressively cleaned the chamber and even polished it lightly with Brasso.
I use a LEE factory crimp die (made the gun actually usable, but still FTF prone).
I have look at what brass is causing issues, and while one brand seemed to cause more issues than the other, it wasn't only that brand causing issues. I feel like thicker brass may be playing a role in this.
I have heard of a few ways to fix this issue, but I'm wondering which one would be best. I have heard of using J-B bore cleaning compound on a resized case attached to a drill to enlarge the chamber, and I have heard that re-cutting the chamber with a reamer would probably fix it. I can get the gauges and the reamer for about $40. I doubt it would take much. Ul;ultimately, I'd like to shoot cast out of this gun, but that doesn't seem likely to happen with the large bore and the tight chamber.
Suggestions. (BTW, the closest gunsmith I would trust is 2-3 hours away and would likely require be drop the gun off and come back a few days later. I'm basically on my own, but I am good enough with tools that I can probably do the reaming on my own without a problem.)
