    Is the 7.62 Tokarev too hot for hard cast lead? It's pretty common to get 1200-1600 FPS out of it.

    I plan on shooting bullets in the 80-100 range since that's what I use for my Nagant. About how fast is too fast for lead?

    You might need gaschecks as your hitting some higher velocity on the top end.

    I shoot that range of hardcast in my 45-70 with no leading but I use good lube in the lube rings. If the bullet your using doesn't have those rings your prolly going to need checks.

    Fire a couple mags check for leading in the barrel. Looks like greyish silver streaks down the bore. Monitor closely for leading as your on the edge with that round even with hardcast

    How about something like these?

    The price is great, and they have the rings and lube (I'm guessing that's what the blue is). The only problem is that they are .313, and my bore is .309 between the bottoms of the gooves, so I'd have to re size the bullets to .311. That's an easy fix though.

    Also, if I was going to use jacketed bullets, what diameter would be best for that bore? .308? .309? .310?

    The blue is lube those will likely work fine without leading if the bore is nice and bright. Always monitor for leading when trying new to the gun cast bullets.

    As for diameter, .313 should be just fine as the range of bullets for a soviet .311 7.62 bore is .311-.313. You don't want a bullet same size or smaller than the bore or you get severe gas blowby which will decrease velocity and accuracy and possibly reliability in ftf fte and cause severe leading. Those shouldn't need sizing

    Also with cast bullets you can use data for jacketed if no cast data exists just reduce loads by 20% but dont go below book minimum

    Those Missouri bullets are too soft. They say "for Cowboy action velocities". That wouild be under 1000 fps.

    You want a Linotype or 50/50 Lino/WW

    I push straight Linotype bullets with gas checks over 1,600 fps in the HK roller block action-ed CZ-52 pistol. The 7.62 X 25 bullets should be sized to .308 diameter. Use a very hard lube. Bullet made for the 7.62 are .308 the Sierra 85 grs. and others are .308. You can go .309 but not necessary. :)

    The bore in this one is .309. Would a .313 bullet still work fine, or is that too over sized?

    Well, I've been wanting to get into casting my own anyways. I have a good bit of soft lead stored away (easily enough for several thousand bullets), so I just need to find some linotype to mix in now. :D

    I thought it was common practice to use lead bullets that were over-sized by .001"-.002" to increase accuracy :confused:

    Replies in bold.

    Try various sized bullets from 308 to 313 see what works best before buying molds and bullet sizer. When you do you want a mold that is a little bigger or same as the sizer and the sizer the size you actually want

    Awesome! Thanks. :D

    I have plenty of bullets in .313, since that's what I had been using for my m1895 Nagant, though that's about to change. Apparently, my Nagant has a .314 bore, so I'll have to go with a bigger bullet. (no wonder accuracy was a bit off)

    I cast,size and TL this little bullet from Lee for my brother to shoot in his CZ-52. Bullet is cast from plain WW alloy put through the Lee .311" push through sizer then heat treated and water quenched to retain a higher overall BHN them tumble lubed. His bore is .309" groove to groove.

    http://leeprecision.com/mold-dc-311-93-1r.html

    Not sure what powder he is using but I believe it's Unique and Bullseye,he makes his own brass from once fired .223 cases that he reforms to 7.62 x 25 and is pushing the load up around 1300 fps. The loads cycle reliably and give excellent accuracy with no leading.

    As to J bullet he shoot both the Hornady .308" 86 gr. RNSP and .309" 90 gr.
    XTP HP. Graf has the RNSP in stock https://www.grafs.com/retail/catalog/product/productId/25653

    Just start on the low end of bullet size and work up till you find that gun's sweet spot.

    To save money buying multiple sizers, try .001 over bore first. That is most likely to give good results. WTS, I shoot .310 cast gas checks through all my .30 caliber rifles, .308, .30-30, .30-06 and 7.62 X 39. It is a compromise diameter that works well enough in all.

    Going too far over size can cause chambering issues

    The CZ-52 has a tight chamber. Using any bullet above .308 can cause chambering problems. The CZ-52 was made to accept the 20% higher pressures Sub-Gun ammo. :)
