Just a question for any of you who reload this cartridge. How mcu can you actually improve your groups? I know that the rifles thaty shoot this cartridge normally aren't know for their accuracy. I've heard that MOA accuracy has been acheived with the .30-30win in some bolt actions guns, because the lever actions aren't capable of that. The 7.62X39mm is balistically comparable to this, although I'm not sure if the case design promotes consistancy. First off, I'd like to know if anyone think the cartridge itself has accuracy potential, and how much you can expect to improve grouping in a military autoloader like an AK-47 clone or SKS.
If you don't think a lever action will shoot under an inch, try a Marlin 336 with a good scope. They won't all do it, but you'd be surprised at how many will! Both my 30-30 and my 45-70 have. At least one other 30-30 I've owned would also do it.
So far as the 7.62x39, My AR15 with the7.62x39 upper will bump right at 1" with a number of loads. Haven't found a true 1" load for it yet, but I also haven't tried real hard. Have some 150 gr. loads in the blocks to try out next time I go to the range. Maybe one of them will be "the load".

In my Ruger mini-30(a rifle not known for accuracy) I have been able to get my groups down to 1.1 inches at 100 yds with handloads. I have achieved equal results with H335 and BLC2. My current best loads are 28gr of H335 and 29.5gr of BLC2 with Lapua brass, Winchester primers and 7.62x39 123gr Hornandy V-max's(currently only available from Graf and Sons). Before I started handloading, my best groups were 3-4" @100yds depending on the brand of ammo.
A friend of mine that has an AK who also reloads independently came up with a similar best load for his AK. I believe his load was 28gr or H335 with Lapua brass, CCI primers and the 7.62x39 123gr Hornandy V-max's.
Both of us started with 27gr of H335 and worked our way up in .5gr increments. Both of us noticed that best accuracy was at 28gr. I then tried going .2gr on either side of 28gr and accuracy was slightly worse(barely measurable at 28.2gr but moreso at 27.8).
As when working up any load for your particular gun, it is always safest to start light and work your way up.

NO!! I have successfully used .308 bullets in the SKS, the .303 British, and the 7.65X53mm Belgian/Argentine Mauser. In the Mauser and a Jungle Carbine .303, I got MOA accuracy with the 200-grain Sierra PSPBT. :lol:

If you are into benchrest style shooting, you would see that the majority of those competing are using .22 PPC, 6mm PPC, and Rem. 6mm benchrest carts. These are ALL based on the 7.62x39mm, m1943 cartridge. Yes, this case design can promote superb accuracy and excellent cosistency. I've personally seen stand. dev. figures in the low single digits with these carts.(the PPC's and Rem. carts.) :sniper:
