Anyone have success with cast in 7.62X25

[Old Iron Sights]

Have a Romanian Tokarev, Lee 311-95-1R and a 309 sizer. I've tried red dot and am working with AA7 now. Not having anything that I would consider success. Best groups so far are around 8" at 25 yards resting my hands on a sand bag. Just tried 6.8 and 6.5 of AA7 tonight. The groups were pie plate size but way high. Anyone find a winning combination for this gun in cast?

I've not tried any cast boolits as of late, but I have had excellent results with herco, unique, and bullseye. 309 is the proper diameter for the projectiles, and I have found that a hotter load with a lighter (86 grain sp in this case) bullet yeilds excellent consistency. Herco in particular fills the case to 90% and rings an 8" plate at 15 yards, with a 95%+ burn. Id consider 25 yards a bit ambitious for my cz52, but then again I haven't tried yet.

Maybe I'm expecting too much?

On a TT33, I'd say that might be it. I haven't heard of anyone ever using AA7 for 7.62x25 either, though. Red dot is a much better bet.

I've had good groups and no leading in the C96 and P.08 (7.65 Par) using HS-6 and NEI 85.308GC.

The C96 loads were from 7.0 to 8.2 gr. The P.08 loads were from 5.3 to 6.0 gr.

Accurate Arms listed the following C96 loads with AA7:
Hornady 86 gr bullet – 6.9 to 7.7 gr
Hornady 93 gr bullet – 6.8 to 7.5 gr
Speer 100 gr Plinker – 6.5 to 7.2 gr

Well, I think I found a formula I can live with. This was 25 yards with a rest. 7 grains AA#7. 3" sticker so that's 7 of the 8 in about a 5" group

You might try sizing larger to 0.311"............... RedDot is a fine powder for the cartridge also.

I'm having issues now with these chambering. Not sure I want them any bigger. This is good enough for me. Gonna file the back sight down some and drift it a little.

The Tokarev TT-30/33's issue iron sights shoot high by design--at 50 arshins (roughly a yard), point of hold with Tok sights was an enemy soldier's crotch. Hold sight picture at the bottom of a B-27 silhouette, and hits will happen at the 8-ring/6 o'clock from 25 yards and the 9-ring/6 o'clock at 50 yards.

My ChiCom Tok has .311" grooves, but like your pistol its cartridge neck would be too large for the chamber when a bullet that diameter was seated. I resolved this in the Tok by reaming the case necks after resizing, minus use of the expander ball. I used the Forster 30 caliber neck reamer for this purpose.

I use the Lee 100 RN with good effect in the 30 Mauser/30 Luger/7.62 x 25 pistols. I seat this boolit to a length that places the middle drive band centered over the case mouth. I then use either the 30 Luger's seater die with roll crimp collar, or the 30 Mauser's resizing die minus decapping assembly, to set a crimp right into the boolit sidewall. Don't over-do this, or that dinky neck will spring away from boolit sidewall and the boolits will "telescope" against the feedramp while cycling.

AA-7 powder was the fuel specced and developed for the Czech version of the 7.62 x 25 for the CZ-52 pistols. It does GREAT work with jacketed or cast bullets in both 30 Mauser/7.62 x 25 and in 30 Luger. BTW--the 30 Mauser and 7.62 x 25 are similar BUT NOT THE SAME. Case length--shoulder datum line--and radial clearances vary slightly, all of which are very slightly smaller in the Tokarev version.

My Tokarev shoots 3" at 25 yards pretty reliably, the CZ-52 has done as well as 2" @ 25 with j-words (Hornady #1522) and AA-7. It has .309" grooves. My Broomhandle is a lot more about style than accuracy, and the jackrabbits that have fallen to its bark (which is loud as hell) were a most unfortunate set of varmints. This pistol comes factory-equipped with what is the most optimistic tangent sight to ever grace a weapon system--set to 1000 meters. I imagine at a half-mile, these 86 grain FMJs might raise quite a welt.

I fooled with the 7.62 Tok back in the late 80s extensively. That was before commercial brass was generally available. I made mine from 5.56 cases which had to be neck turned, all 1700+ of them. I used the Lyman 313249 sized 0.311" and around a book max charge of RedDot. It has shot well in numerous Toks, CZ 52s and Broomhandles with better than ball accuracy.

Like 45-2.1, my first brass for this caliber was "derived". I used W-W 9mm in Mag, and gave it one pass through the RCBS sizing die--then a trim. First trimming got done with the Forster trimmer, then I "graduated" to an RCBS file-trim die. Time-consuming bit, either way. I still have more than half of the original 500 W-W cases in residence.

Starline brass is first-rate in this caliber. Fiocchi brass is good stuff, too. More recently, I've purchased WWB ammo (Win White Box) in 7.62 x 25, and the brass in all three of these makes runs well with .311" boolits or .312" bullets in the tight-necked Tok. I haven't had the "telescoping bullet" issues with these 3 latter brass makes during the feeding cycle, either--very infrequent occurrences these days.

The report of full-tilt 7.62 x 25 ammo from a pistol barrel is pretty fierce. Ear protection is a MUST.

None of my pistols in this caliber are "match grade". The CZ-52 seems to be the most accurate, and is a capable varminter and small gamer to 50 yards or so. I think the game-taking performance of these 30 caliber pistols--to include the 32 ACP--would be well-improved through the use of truncated-cone boolits similar in form to the GREAT Lee autopistol TC designs. Early days with a gas-checked #311419 has shown this boolit to be accurate in the CZ-52 and quite lethal on jackrabbits. The checks boost component price significantly, and might be superfluous assuming a well-fit boolit.

We're getting new never issued Polish TT-33's with matching mags for $220 here in Canada as of late.Made by Random factory #11 most in the 1950's range.No importer marks to ugly things up or caveman Gov't added safeties.An arshin is a "pace" about .78 of a yard.before they went metric.Will be getting dies for mine and load some 86gr Hornady's or experiment with 100-110gr M1 carbine bullets.Will try AA7 but I have lots of 800x ,Unique and Win 296.Picked up 2 cases of Sellier and Bellot military ammo yesterday [2280 rds per crate] but it's corrosive of course.Would like to rebarrel a Spanish Destroyer carbine in 7.62x25 if possible........Harold

Just an update. The existing mold (311-95-1R) was honed out slightly to make it fit my nagant bores better. I ran these through a 309 sizer (more like 308) for my Tok and seat them very deep so they will chamber most of the time. Accuracy has actually not been too bad. I have since ordered the Lee 311-100 which has a longer nose and throws about 310. I ran these through my sizer so I end up with boolits about .308-.3085. When loading up the first ones, I tested each one in the chamber and they all slid in fine. After firing one or two rounds however, non will chamber. Looks like it's the age-old tight chamber problem with the tok. Read some other posts here about using a 340 reamer to open up the chamber. Not sure how that compares to the current brass/bullet I have. May have to put in some bench time.

[9.3X62AL]

Reaming the chamber's neck area is the RIGHT approach to the issue, for sure. Goodness knows, it's a dinky area.

[Old Iron Sights]

Looks like I'll be ordering a spare barrel to screw with. The current barrel is real good with prvi ammo.

[JHeath]

Conveniently, 0.340" auto valve guide reamers are available for cheap. I got mine for $22 but haven't reamed my Tok yet, too busy with other projects. Think it'll work though.

BTW does anybody here know the twist rate of an M57 Tok?

[Old Iron Sights]

Ouch. Barrels are scarce and expensive.
Could this be done in a drill press and vice or does it require a metal lathe or milling machine?

[JHeath]

I think it can be done by hand with a tap handle and cutting oil. But like I said I haven't gotten around to it yet. If you go through Clark Magnuson's posts here or on other forums you'll see he re-chambered 9x19 Chinese Toks to 9x23 Win using only drill bits(!). Said he used a lathe but that a person could do it by hand, holding the bit in a drill chuck.

[Old Iron Sights]

Hmmm... One more thing on my to do list.
My rounds will chamber fine in a clean chamber but that's out the window after two shots.
