Anybody have chronograph info, or link to such, of Krinkov velocities?

I'm considering getting a Slr-104ur and registering as SBR.

If you look to the top of the "Krinkov" sub, you will see a post "AKS-74U Nomenclature". There is a little chart in it that states the muzzle velocity of 735 meters/sec. This is the correct value for a standard 7N6 5.45 round.

Just wanted to see if anybody had tried it out and had first hand, real-world data over projections.

10 shot group with my Bulgarian Krink using Russian 7N6 gave 2489 FPS. 10 shot group using Bulgarian Circle 10 7N6 gave 2421 FPS.

For comparison with my AKS-74:

Russian - 3073 FPS

Bulgarian - 3000 FPS

42*F and 30” Hg when I did the test.
