Now all US published data for the CZ52 and Tokarev is as wimpy as 30 Mauser data. Johan Loubser at AA came out with new data in 2004 that was 34 kcup for the the CZ52. I pointed out that the roller relief cut under the chamber left a spot where the chamber was the thinnest of any pistol chamber I ever measured. I wrote to AA and told them they had problems. Someone got hurt at my range, but I don't have any details. It used to be thought that the CZ52 used hotter ammo and was stronger than the Tokarev, which ran hotter ammo than the 30 Mauser in the 96 Mauser pistol.ĬZ52s started blowing up at shooting ranges with surplus Tokarev ammo. Ted Curtis at AA published data for CZ52 only in May 2000 for 42k c.u.p. The Czech ammo that the CZ52 were designed for was running 42,000 c.u.p., the same as all Tokarev 7.62x25mm ammo, except Russian, which ran more like 30k c.u.p. In 2000 Accurate Arms made some measurements. Much more than the bullet was designed for so I wont post the results but they were interesting to say the least.The Army wrote or paid to have written a document in 1970 that said that the CZ52 was stronger than the Tokarev. I also tested the 85 grain 32 Caliber XTP and got some amazing velocity. The 7.5 grain load shoots like a laser, we had a blast blowing up milk jugs out to 50 yards I think this would make a decent round for Coyotes and other small predators and varmints. He got 13.9" of penetration and the Bullet expanded to. They don't look too bad but there was some cratering.Īnd here's a look at brass fetchers gel test of this bullet at 1550 fps. Here's a look at what the primers look like after being shot. Even though Brass fetcher had good results in his gel test at 1550 fps I think 7.6 -7.7 grains of power pistol at around 1450 fps is optimal for this bullet and should bring the pressure down very close to the 3200 bar limit. Hornady rates the 100 grain xtp bullet for 1550 fps max and states that even 1500 fps could be too fast for this bullet at close range in their 327 Federal Magnum load data section. I'm also using a new production Zastava M57A which might be stronger than your average 70 year old TT33, but I'm not sure about that. I've noticed Quickload slightly underestimates velocity with Power Pistol and Overestimates velocity with H110\W296 in this round so actual pressure could and most likely is slightly higher than 41,282 psi.
Quickload has 34,809 psi as max pressure so again please please be careful and work your way up if you plan on duplicating these loads. I'd feel terrible if someone hurt themselves.Īccording to Quickload 8 grains of Power pistol should propel this bullet to 1502 fps which is very close to the results I obtained and 41,282 psi Which is quite a bit higher than the CIP 3200 bar (36,250 psi) pressure limit for the 7.62x25 Tokarev. 2 grain increments and recommend you do the same. Please be careful and work your way up if you plan on duplicating this load. I worked up to a max load of 8 grains of Power pistol with a cartridge overall length of 1.320" and CCI 500 standard small pistol primers in NEW Starline brass.
308" lee bullet sizer to bring them down to. I just finished testing the 100 grain 32 caliber XTP's that I ran through a. I'm quickly becoming a fan of this cartridge it's a little hotrod. None of these loads have what I would call excessive recoil. Power pistol is the Tokarev powder from now on for me.ġ2 grains W296, Quickload estimated pressure is 28K psi and 1265 fps, this load averaged 1241 fps over the chrony - This was a good mild plinking load with good accuracy.ġ2.5 grains W296, Quickload estimated pressure is 32K psi and 1339 fps, Actual average velocity was 1302 fps, I doubt this bullet meant for the 30 carbine would expand at this velocity.
#RELOADING 7.62 X25 TOKAREV MANUAL#
The cases looked great after firing with no smeared primers or any other signs of excessive pressure, unfortunately I forgot to measure for case head expansion.Īll rounds were fired from a new production Zastava M57A - $250 at Budsġ5.2 grains of W296, Quickload estimated pressure is 40K psi and estimated velocity is 1630 fps, This load averaged 1558 fps over the chrony - I expected more from this one, W296 is obviously too slow for this cartridge I don't care what Hornady's manual says.Ĩ.5 grains Power Pistol, Quickload estimated pressure 40K psi and 1580 fps, averaged 1629 fps over chronograph - This was much faster than expected and I will be loading 8 grains from now on. I used brand new S&B brass and primers which I pulled from loaded ammo (Clark says S&B brass is the strongest for this round). If you plan on duplicating these loads work your way up and don't hold me responsible if you or your gun blow up. Some of these loads are over the recommended 35K psi limit for this round and are right around 40Kpsi according to Quickload.
