The Russians killed tens of millions of Asians, and tens of millions of Europeans, and tens of millions of Russians over the last 100 years. They may be pretty good at making powders.

Yep Just not so good at making food

Just for illustration, and humor, I think it's obvious that the tubular powder marketed as FSP759 was not effectively flash suppressed...
Pictures from 8x57, 175 Privi, 20 inch barrel. Non-max load, but pretty reasonable.

On a serious note, I do wonder if it was surplus military at all, and perhaps surplus Kazan for commercial use.

IIRC the US military shooting team were using Russian primers at one time. I bought 10’s of thousands and no regrets.

I would try their powders if the price was right.

The Tula small rifle magnum primers were great in my 223 boltgun with a full case of n150. I made high master in long range with that load, I got single digit es’s for a 20 shot group.
I only have 1 hundred left.

Cheers,
Steve

Interesting. Someone gave me 500 of those primers and I have a very accurate bolt gun to try them in. My go to powder is IMR 8208 with 55 gr SGK’s.

I have used both; did not see any difference in there primers; powder started low and worked up to desired FPS; AMU used st.marks powder for years; It all goes bang; just use causation when loading ?
