    As a side note, my understanding is that the bore is the same and they (the Russians in WWII) used the same rifling cutters on all 7.62 for simplicity. Smane bore same twist.....

    Not according to my reloading books. 7.62x25 = .308 dia; 7.62x39 & 7.62x54r = .312 dia. Now, someone has already said it works OK with a converted .39 barrel, so I guess it doesn't care that much.

    And the bolt head of a 7.62x39 won't fit the 7.62x25.

    Winn, now I wonder.

    Correct on the bolt head - you need an AK-74 bolt head. However, I've been reading about the WW2 builds and unless I'm mistaken, they used the same barrel blanks for both the Mosins and the PPSH. I think. Kinda hard to figure out rumor from actual fact on some of these sights.

    However I seem to remember that the .308 vs. .312 discussion was a moot issue when talking about the x25 caliber. I don't think I'd ever put a .312 into a .308 barrel, but I think I would not have a problem with putting a .308 into a .312 barrel, so long as there is enough seal to prevent excessive gas bleed.

    Now that I think about it I asked this a while back, and the builder said it shot well, but they did not chrony it so there's no hard data to show how much gas loss is happening with the extra .003" bore.

    I'm not sure about a sleeve - how would the first 1" of the barrel be threaded? Doesn't seem like it would work? Looking again at the reloading manual, the neck on the Tokarev is too short vs. the x39 neck. Does the sleeve have a threaded front that you align to the barrel threads? Someone please educate me on the sleeves!

    hcpookie I remember reading somewhere the ppsh was a nagant bbl blank cut in half or thirds.. can't quite remember. Also there are conversion sleeves for 30-06 to 308 and 762X45 to 762x39. They were to be held in by loctite. I have slugged a few nagants and found .309 to .314 bores. And finally there is some reloading data on using 308 bullets in 7.62x39 with satisfactory results.
    So I guess what I am trying to say is make a chamber insert and try it.
