7.62x39 subsonic
« on: May 02, 2015, 12:54:30 PM »
Been looking for recipes for 7.62x39 subsonic.  Only one I could find uses a powder I've never heard of Vihtavuori N160 Smokeless Powder.  Is that available anywhere around here? w/150gr bullet and 1.27 grams of powder.
Anyone have any other recipes?
"Assuming" it should be pretty similar loads to 300BLK subsonic, like accurate 1680 with 220gr bullet ~11grain.
I'm thinking maybe trying to reverse engineer the ones I have before I run out, Engel "Jackhammers" 220gr. 
thanks!

where are you going to get .311" 220gr bullets? or are you just going to put .308 down the larger bore?

.308 and .311 are only .003 different and seems to be common to shoot .308 in .311 barrels.
It worked for me, here is a wolf 7.62x39 (measures .311) and the jackhammer subsonic 220gr measure .308.

 the 303 british and I think the 7.7 jap both use 311-312 bullets, they might make a heavy you can use,

   what are you shooting these out of?  I use cast 220 grain in my 300 whisper

From what I can see a .308 220gr should work.  Just wondering if anyone has experience/recipes for this.
And, if this Vihtavuori N160 Smokeless Powder is available locally?

USE THIS DATA AT YOUR OWN RISK !!!!!

To make Subsonic 7.62x39 I start with Winchester brass and Winchester large rifle primers.
17 grains to 18 grains of Winchester 748 powder.
(17 grains = 1040) ( 18 grains = 1098) FPS.
Sierra 180 grain spitzer, diameter .311 code # 2310
This bullet is made for .303 Brit. but works well for this application.
Load to the same OAL as ball.
Out of my Colt 16 inch barrel I get around 1 inch groups at 25 yards, opens to about 5 inches at 100 yards.
This load will cycle my rifle, but just.

You should test your loads over a chronograph because when trying to stay under speed of sound little things can make a big diffrence.

AS WITH ANY LOADING DATA USE AT YOUR OWN RISK !!!!!


crappy accuracy, but may be a starting point for you as far as the powder load goes.

I do not reload, I'm am just passing along what the Googles found in a search.
