XTP bullets in 7.62x25 Tok. (.312)??

I have a nice Tokarev TT33 I'd like to brew up some loads to make it a viable self defense piece. I slugged the bore and it came out to .312 !!! I know Hornady makes the XTP in .30 and for the .32acp. Would I be good using the .312 XTP in either 85 or 100gr., those are availabe at a local shop. Odd thing is, the gun is reasonably accurate with old surplus ammo (those bullets mike at .306) and I've loaded some accurate stuff with the 100gr plinker (.308) bullet. The bore does slug out at .312, judy odd I think. I tried loading a 32acp (311) bullet from a factory Federal round, seated proper but no powder or primer. That combo hand fed and ejected with no problem. The .312 XTPs I can pick up tomorrow. The plinker bullet has impressive penetration, but doesn't expand at all in any medium I've tried.

My Yugo Tokarev barrels, both commercial and military, all slug .301/.313. I believe the Soviets set the original standards for bore dimensions for MG's, SMG's, rifles, and pistols so that all of the pipes could be produced on the same tooling. The Mosins with like-new barrels that I have slugged all measured .300/.312 to .302/.313. All of the rifle bullets measured .311, and all of the pistol bullets have measured .307. I currently have a supply of military pistol bullets from the tear-downs of surplus, and some of the Hornady .309's, but I haven't loaded any yet (I did buy a Lee factory crimp die to eliminate any bullet set-back during feeding). I appreciate the info that the chamber dimensions may accomodate .311 or .312 bullets.
Personally, I would not attempt to match published factory velocities (PRVI takes their 7.62x25 ballistics from 9 1/2-inch - SMG length - barrels) and I think I'll be content to load at around .30 Mauser ballistics for most shooting. [:)]
