.30 Mauser or 7.62 X 25 Tokarev

[Rod B]

Is anyone casting boolits for this caliber?

If so what mould has worked for you?

[singleshotbuff]

Rod,

I haven't started casting my own for the 7.62X25 yet, but I will shortly. I just purchased a Lee 100gr, RN, .311" mold that I plan to give a workout when the weather breaks.

I have shot some cast boolits outta my CZ-52, 7.62X25mm, that I got from a fellow member. They are 120gr, kind of a RFN, they look just like the boolits in the Cast Boolit logo. They were .314" as cast, and I think they came from an old group buy. I've been shooting em, sized .309", over Unique in S&B brass. They shoot great and I think they're clocking about 1100 over the Chrony (I'll have to look up the exact velocity on my old computer). I'll be happy to share my results with the new mold as soon as I get a chance to try it.

What gun are you shooting? I really like my CZ-52.

I use the Lyman 313249 85 gr rn and 313226 93 gr rn in my polish Tok and Chinese Tok copy.

Following loads from a CZ 52:

Starline case WSP primer 4.5 W231 Lyman 85 RN 1203 fps
" " " " 5.5 W231 Lyman 85 RN 1379 fps
" " " " 5.0 Bullseye Lyman 85 RN 1338 fps

" " " " 5.0 Bullseye Lee 113 soup can 1181 fps


I have no idea of how safe these loads are in a Mauser or Tokarev, approach with caution! If shooting in a CZ 52, take a sharp-eyed kid along to chase brass.

I have a
Lee 6-Cavity Bullet Mold 311-93-1R (311 Diameter) 93 Grain 1 Ogive Radius
If you're interested, used it once for a 32-20. Didn't work I needed .312-.314 diameter.

Lyman #313249 and the Lee 100 RN have worked for me in the Broomhandle, a Chinese copy Tokarev, and a CZ-52. I have some Lyman #311419's--a 311316 missing the middle drive band, weighing 92 grains. These are loaded atop 5.0 grains of WW-231, and await range testing.

[Rod B]

Thanks for all the responses.

I am shooting a Russian Tokarev TT33.

So far all I have shot in it some 1953 production Hungarian surplus ammo. It is steel cased with a steel core 85gr bullet. This stuff seems very hot & has somewhat inconsistant velocity. I suppose I can't expect match performance from ammo that is 55 years old.:mrgreen:

A friend has the 93gr Lyman mould & has offered to lend it to me. I will try this before I purchase a mould.

Here's a pic of the Tokarev. It's in excellent shape & cost me $295.00

Nice TT without the safety that was required on later imports. I hope it shoots as good as it looks. Mark

[Bigger behind the trigger]

Do you still have the mold?

[GhostHawk]

Lee .314 90 gr truncated cone tl, sized as needed (.311/.312)

First bullet that did not get me a would not fully go into battery ever 5-8 rounds.
It just plain ran.

I set the first drive band just outside the case, crimped in the hollow behind it.
3 grains of Red Dot and it shoots well, no problems. Starline brass.

I have been using the Lee 311-100-2R, 100 gr round nose, plain base. A standard load for me is 6.0 gr Unique. I'm pretty happy with this. That round is fussy about crimp and max case length. If they are just a little too long, they won't chamber.

I have a Czech CZ52. I have been shooting an Accurate shape: 31-085BG but I ordered it without the lube groove because I powder coat them.
I've been shooting them over W296 and they are fast, have recoil and BIG muzzle flash. Super fun, super loud and super accurate.

I had a really hard time with the CZ. I tried Unique first and I started getting flattened primers before it would even cycle the gun and had very poor accuracy. I shot a few with A2400 and that seems to work pretty good but I didn't have enough oomph to get really good accuracy with the loads I tried - should up the powder a little and try again. A2400 is more appropriate than W296.

BUT I read that AA#7 is the powder you want. I have yet to ladder my boolit up with that powder, but I've been using it with 40 S&W and 357 Sig recently and really like it.

Beyond loads, that cartridge was pretty tough to get dialed in. I wrecked at least 5 cases initially.

Good thing is: You can make more 7.62x25 out of .223 cases... And you can get .223 by the bucket fulls at almost any outdoor range.

I played with a CZ-52 for a while and was impressed with the power of the round. Eastern bloc ammo producers were not timid in how they loaded their ammo. The downside to the experience was not the round, but the dimensions of the bore and chamber. The barrel slugged at .310 in the grooves, but the chamber neck was so small that, with thick-necked commercial cases, a .308 boolit was the max that would chamber. Accuracy of cast sized .308 in a .310 barrel was predicably poor. I pulled some bullets from surplus ammo which had thinner necks, many of which cracked, and loaded the surviving cases with 123gr FMJ .310 jacketed over a reduced charge and chambered one at a time. The accuracy vastly improved, the same results being reproducible with cast .311. So until I can ream the chamber neck large enough to accommodate the thicker necks of boxer cases using full diameter boolits or get a barrel so chambered, I think I'll pass for now.

I thought it would be entertaining to build a small bolt action switch-barrel appropriate for 7.62x25, 9x23, that .224x25mm, and possibly a rimless .256 Win and use it for pests, as well as experiments with heavier boolits in a long barrel. I wanted to know how fast I could get the 150gr Lyman 311466 going with 1680, for one thing. Small case efficiency can be impressive. Still looking for an appropriate action. The Spanish Destroyer carbine would be a candidate, but one hasn't knocked on my door just yet.

I think that 7.62x25 might be a bit must for a Destroyer action.

I had John Taylor rebarrel a Remington 722 to 7.62x25 for me. It has a single-shot loading tray, ghost-ring peep sight and Picattiny rail for optics. 7.62mm 148-grain FMJBT bullets get 1370 fps using 11 grains of IMR4227. Ballistics of 7.62x25 factory loads are similar to the .30 M1 carbine, but with better accuracy.

That single shot really looks interesting. All the 7.62 x 25 kits look like killer winter projects.

Also wondering if anyone rebarreled an 9mm AR to 7.62 x 25? Some of the kits claim they use 7.62 mag on 9mm conversions.

So, my barrel is a new barrel and it is .308. I size my boolits to .309 and I use this shape:
243861
I get great accuracy with factory ammo -- like 3" groups at 100 yards. But with this W296 load and cast boolits, I get much better accuracy.

I will eventually get to testing this boolit with AA7 and / or AA9 as AA7 is pretty equivalent to the eastern block charges....
