Powder in 7.62x39 ?

[Capn Jack]

Opened up some Russian and Ukrainian 7.62x39 and only found 10.4 gr of powder in them. WHAT ?
I've looked around and found several published loads for various powders and most
are listing around 30 GR. What are the Russians using ? It must be HOT.

The comm block stuff I have taken apart has had massive fluctuations in powder charges, bullet weights and crimps. Quality control is well, non existent. Pretty sure each faction uses its own powder. I've seen tulammo 122gr bullets range from 116.3 to 125.2 from the same case lot.

It might be fun to yank bullets from a large sample, maybe 25rnds. Then even up the charge weight of powder, if it's different in the sample cases. Reload the bullet and take them out and test for group sizes. What brands were they?

With ammo quality like that it's no wonder so many Ruskies are dying over there.

Wolf steel case HP Berdan primed. They had been buried and the cases were all badly corroded. We pulled them for the bullets. Now have over a pound of powder and curious. Hate to throw it away

What was the average charge weight?

I believe it was 10.4.

What was the average charge weight?

10.4 Gr.
The grains have a cylindrical shape but they are very tiny

Your free service has value well beyond what we paid for it!

Man, it would seem to me with quality control this non-existent there would be more ka-booms reported with AKs, SKSs etc. - but maybe they intentionally go 'light' on the powder charges to prevent this.

I do what I can.

The only stupid question is the question I ask

I had thought the charge weights were all over the map. After rereading the thread I see it was the bullet weights that varied.

Thinking it might just be a hot powder as it almost looks like a pistol load.
