New parent of a Romanian TTC. Brass is so hard to find I tried cutting down 223 brass to .980 inches, reforming in the Lee sizer die, ream the inside neck and trim to 9.80 ctg oal. I made a dummy round and loaded it into the mag, pulled the slide back and let go. Round loaded normally. Problem is it was more tahn a little excessively hard to work the slide to eject the bullet. A second dummy round did the same thing. Using a magnifying glass i insected the brass for any telltale signs of what might be causiing the problem. Only thing I noticed was a burr on the edge of the rim as if the extractor exerted undue pressure. Any suggestiions? thanks Larry
I was going to say just order some Starline Tokarev brass or you can use the Starline 30 Mauser brass since it's actually made short and will work but I noticed that nobody on line has any so I guess your plan is the only workable plan. I measured the thickness of my Starline Tok brass neck is 0.012" to 0.013" thick and the overall length is 0.96" but keep in mind Starline Tok brass is always short. With a .308 bullet seated in the Tok cartridge case the neck outside diameter measures .329". The outside diameter of the loaded Seller&Bellott 7.62 neck is also .329". One thing I noticed with the Lee 7.62X25 FL sizing die is the expander ball is not really the correct size and so I got a case mouth expander kit to make seating a bullet a bit easier. If your neck diameter is the same as mine with a .308 bulllet in place than recheck the case length. As I found with the Starline brass, a little short is not bad but a hair long can be a problem. If all else fails use a Sharppie black ink felt tip pen and coat the neck and bullet and rechamber your dummy cartridge. extract the cartridge and see if any of the black ink had been scuffed of the neck (especially the case mouth) or the bullet. That would indicate undue contact with the chamber. I hope this helps -- if you get it figured out please post the info here because I may have to start using .223 brass if the Starline brass doesn't show back up.

I don't know if you're still working on the problem or not. Like I first said, the commercial Tokarev brass is not available anyplace but, as a side note, Starline 9mm Winchester magnum brass will work although it's a bit longer at 1.15" but I've used it to make Tok cases and the necks come out perfect. If you would want to try some, Midway has it at this URL www.midwayusa.com/product/941640325/starline-reloading-brass-9mm-winchester-magnum It will get you some cases to actually shoot and also to use as a sample to copy with you .223 brass.
Thanks for the measurements 22Boomer. I decided to go the easy way and order some new 30 Mauser brass. I understand the differences in outer dimensions are meaningless. I plan to continue the 223 conversion project but not right now. Larry
