Czech 7.62x39 Velocity

[y2k]

Has anyone ever put Czech Surplus 7.62x39 over a chronograph? I was wondering just what is the speed. ie is it on the hot side?

I put 10 rounds of S&B (Czech) over my chronograph last February.
High vel ; 2416 fps
Low vel: 2353 fps
extreme spread: 63 fps
Average vel: 2383 fps

I also did Russian surplus & Chinese surplus ammo the same day.
Russian was 2354 fps
Chinese was 2345 fps

Chinese had smallest extreme spread (40 fps) and gave best accuracy @ 100 m. (2.5" group with SKS with Bushnell TRS25 red-dot sight)
