This pistol cartridge packs a real punch. Surplus ammunition can have velocities
ranging from 1450 fps up to 1650 fps from pistols and Sub-
7.62x25 85grn velocity: 1647 fps energy: 512 ft lbs.
9mm 115grn velocity: 1190 fps energy: 361 ft lbs.
40S&W 165grn velocity: 1060 fps energy: 411 ft lbs.
45acp 230grn velocity: 880 fps energy: 396 ft lbs.
I have been playing with this cartridge for over 15 years. My first firearm in
the Caliber was a Chinese type 54 pistol which is a copy of the Russian tt-
My next firearm in this caliber was a AR-
In early 2010 I decided it was time to take it to the next level, an AR-
During the time the barrel was at Teppo Jetsu I contacted a company that was producing a mag well adaptor designed by Marty. Heavy Metal Co had taken up producing the adaptors for the AR15 mag well to allow the use of PPSh 43 Magazines. Tim at Heavy Metal Co is making a great product and I owe him a big thanks. If it had not been for the production of this adaptor I would probably not have been as motivated to go from the drawing board to cutting metal on this project.
After Marty finished chambering my barrel and sending it back to me, I then had
to mount the gas block and drill a Gas Port. I had decided to try and make this work
with as many off the shelf parts as I could use from Hogan Manufacturing. This put
me having a gas port that is between a pistol and Carbine length. It leaves the front
of the gas block I used even with a Carbine Rails system from Hogan Manufacturing.
I have been fortunate enough to get in touch with a few people that have been playing
with this caliber in the AR-
Here is some video of the first time test firing with everything assembled....
Each one of these videos was filmed during test firing sessions. The last one was the first time I had taken it out to test a brand new full auto carrier design.
I mentioned earlier about getting higher velocities from a sub-
Norinco Yellow Box Projectile: 86 grn FMJ
High: 1874 fps Low: 1798 fps Avg.: 1834.9 fps
E.S.: 76 S.D.: 22.2
great ammo, pretty hot, runs fairly clean considering age and origin…not corrosive
S&B Projectile: 86 grn FMJ
High: 1878 fps Low: 1845 fps Avg.: 1857.7 fps
E.S.: 33 S.D.: 10.4
Functioned fine, cycled great. Very consistent.
Wolf Gold Projectile: 86 grn HP
High: 1671 fps Low: 1584 fps Avg.: 1635.8 fps
E.S.: 87 S.D.: 22.1
Does not cycle action enough to catch next round. Would love to be able to buy these projectiles for hand loading a defensive/hunting ammo.
Romanian Surplus Projectile: 86 grn FMJ
High: 1869 fps Low: 1798 fps Avg.: 1847.7 fps
E.S.: 71 S.D.: 21.9

Polish Surplus Projectile: 86 grn FMJ

E.S.: 92 S.D.: 28.5
Corrosive. Really dirty and smokey
I have also enjoyed reloading some hot little rounds for this carbine. I have found that the wolf/privi brass can handle higher chamber pressures. While starline brass is plentiful, it is a little softer, even though, with my supper sonic loads, I have yet to have any real pressure signs with either brass. I have loaded Sierra 85 Grn FMJ, 110 grn FMJ and HP projectiles. If anyone knows a source for the Wolf/Privi 86grn HP projectiles, please let me know.
The real challenge with this cartridge was finding the Sub-
But of course I could not just leave it alone........
Now that I had it dialed in. It was time to take it apart. Barrel and gas block went out for heat treat. I went with this since I am going to run corrosive ammo. This was a very fun project to put together and has drawn a lot of interest from many people.
But it does not end here. Now that it was finished and re-
This powerful little bottle-
Surplus ammunition is available from an assortment of Russian Allied countries. The cost of this ammunition for now (2009/2010) is rather inexpensive, ranging from 7 to 10 cents a round for corrosive ammunition. Reloadable brass cased ammunition is also available from Wolf, Sellier & Bellot and Winchester. New brass is available from Starline.
