7.62x25mm reloads

[Skyhawk23]

Hello All,

I don't know if I am at the right place to ask the question.

But has anyone on here done anything like a 7.62x25 reload?

If so what dies, powder, bullets, AP that was used to reload and lastly load chart to use?

Thanks in advance for all the inputs,

[Skyhawk23]

Thanks TIM,

I will take a look just having problems locating primers. But did you say you used Red Dot? I don't see that on the chart link you send.

23: I load my Tok with the Lee SWC or RN powder coated. over HP-38. I made cases out of cut down 223 brass because I have a bucket full but unless you have extra time it's good to just buy Starline brass. Gp

here is a clip from the Lyman Cast Bullet Handbook

I used AA#7. My bore sluged at .314, but fired brass indicated it would release .313 bullets. So I ran 32 cal 100gr XTP. With these tolarances I was getting really close to clays on the 100 yd berm. Never could hit one. But a 8" gong would ring 8-9 out of 9.

Lee used to make Tokarev dies, not sure if they still do or not, that was the data I was using. Firing full power loads was almost guaranteed to loose brass.

Reloading 7.62x25 is easy, thanks to affordable brass of high quality brass from Starline, and Lee dies.

There is no need to frustrate yourself cutting down, resizing and neck reaming 5.56mm/.223 brass to feed your Пистолет браконьера or Pistolet brakon'year (Poacher’s Pistol).

Before loading for your 7.62x25 pistol you will want to make a chamber cast.
Measure both chamber neck and ball seat diameter.

There is wide variation in chamber diameters in the east bloc stuff and groove diameters ranging up to .315. I've never seen a 7.62x25 barrel smaller than .308” groove diameter, but I have seen chamber necks as small as .330” which precluded loading bullets of diameter larger than .308”!

A charge of 5 grains of Bullseye was recommended by Hatcher for the 7.63 (.30) Mauser. It is also listed by Lyman. This starting load won’t cycle 100% in my Cz52 or the TT33 with the Accurate 31-087B, but does with the heavier 31-100T. RCBS Little Dandy Rotor #10 meters an actual charge weight averaging of 5.3 grains of with current Alliant from my measure and cycles both pistols reliably with either bullet. Velocity approximates PPU at 1400 fps with Accurate 31-087T, or 087B and 1370 fps with 31-100T. It approximates the .30 Mauser at 1300 fps with the 90 grain Hornady XTP.

“Magnum pistol” powders : Alliant 2400, H110/W296, and VVN110 all work well in near case capacity full loads. With the 7.62x25’s short neck, bullet pull may be inadequate to prevent bullets “telescoping” into the powder space, if bullet fit in the sized neck is not correct. Bullets suited to the M1 Carbine work best when a case full of slower-burning powder provides support to the bullet base, in the same manner as if loading black powder in the .44-40 Winchester. Having the bullet base protrude below the neck-shoulder junction does not cause problems when jacketed bullets are loaded when slower-burning powders such as #2400 are used which fill the case. With fast-burning powders and loading cast bullets recommended practice is to avoid deep-seated bullets to minimize risk of gas cutting and bullet base deformation. Good results are easily obtained with bullets optimized for the 7.62x25 such as the Accurate 31-087B and 31-100T.

Based on previous success in the .32 ACP I decided to try Olin AutoComp in loading the 7.62x25. A charge of 7.4 grains was metered using RCBS Little Dandy measure rotor #9 which also meters the 5.0 grain start load with Bullseye. This proved satisfactory giving 1353 fps with the Hornady 86-grain SP and 1450 fps with Accurate 31-100T.

Water jug tests with the Hornady XTP were impressive, blowing the first gallon jug to smithereens in a manner similar to 110-grain .357 Magnum loads. The XTP bullet expands to about .50 caliber, stopping in the third gallon jug, denting its far side, not exiting. This is entirely adequate penetration for a defense load. PPU FMJ loads shoot clear through a 40-inch stack of water jugs and whistled through the trees downrange, as would be expected.

Test firing my Polish copy of the TT33 there were no surprises. Point of impact firing PPU FMJ with its fixed sights was about ½ inch high at seven yards, two inches high at 25 yards, four inches high at 50 yards and “dead on” at 100 yards. Sandbagged, handheld groups were about 3 inches at 25 yards, cast loads a bit better. All manner of cast bullets of various shapes fed reliably, even the Accurate 31-095T which has a ¼” meplat! The advantage of a bottlenecked case! The start load from Lyman, 5 grains of Bullseye occasionally bobbled with 85-87-grain bullets, but cycled reliably with Accurate 31-095T and 31-100T. Increasing charges to 5.3 grains ran every cast bullet tested!!! The RCBS Little Dandy measure Rotor #13 measures about 10 grains of Alliant #2400 which cycled the guns well. Velocity was 1277 fps from the TT pistol with the 93-grain Norma .307” FMJRN, and 1777 fps from the rebarrelled Remington 722. Plainbased cast bullets of 13 BHN alloy did not lead severely, and shot well in the pistol, but did lead badly and shot wildly at over 1800 fps in the 20” rifle. Data are summarized in the accompanying table.

[Skyhawk23]

Thanks,

I will do that since I don't have any 223 cases.

[Skyhawk23]

Cool,

I will take a look at my Lyman loader book, and maybe the Hornady as well.

[Skyhawk23]

Good info. will look into getting a set, so when i have enough brass to reload I am ready

[Skyhawk23]

Outpost,

Damn that is some good data and info. Thank you very much.

I will cut and paste this into my Doc folder and print it out for future reference.

Thanks again.

[dtknowles]

I used Lee dies marked 30 Mauser. I used Red Dot powder and a variety of bullets.

There is lots of data out there. Here is one site.

IF you trim down 223 brass, you will need a reamer to open up the inside of the neck seeing brass is thicker near the base.

I've had good luck with the Lee 311-93-1R powder coated over around 5 grains of BE

The new Lyman 50th edition has load data for tokarev

[mf79]

I have done it with 223, have to trim case necks since not uniform. I was reaming inside hole but its a pain to hold the case so I used a 308 win sizing die and screwed expander to come out bottom and expand the neck then ran it in neck trimmer so neck is uniform. if not they dont chamber.

[gpidaho]

I know there's likely a good reason to neck ream the cut down 223 brass to uniform the neck thickness as that's the way I've heard the story. Well I didn't want to pay the $30 for a reamer when I already owned the tooling to neck turn the cases. I may be missing the point but removing the brass from the inside or the outside seems like 6s to me. The cases work just fine in my Tok. Gp

[Oyeboten]

I'll give this a try!

I have a CZ 52 and I have an old IDEAL Mold for the .30 Mauser Boolit...I'll stiffen up the Lead from my usual 'soft as can be' ( for the old BP and early smokeless Revolvers ), so it can hold up to this kind of acceleration.

[rbuck351]

I have a CZ52 and a tok and both require neck turning or reaming to thin the necks so I can use cast boolits large enough to fit the bores. I have a mini lathe so outside turning is my choice but either way works. I have made cases from both 38 spl and 223 before any boxer brass was available for the 7.62x25 and 30 mauser was rare. Now with starline brass and S&B ammo available I won't be making any more.
