I do have the long version. A freind of mine set it up for me.940FPS is the 1st shot at a 220 bar fill. And the 26th shot was down to 910FPS I HAVE it written down somewere
Do you have the long version? That’s a good amount of shots from a 220 bar fill shooting at 940fps, I think 870-900 fps is optimal speed for shoot count ,sound and accuracy.
Good to heard that! Did you try to install the new valve stem?
My pellets are coming out at 940Fps. At 220 bar fill im getting 28 shots over the chrony
Looks like another valve from Russia has been sent to me from ED to replace the other which did not fit correctly. I’ll update when I get the gun sorted gents.
Thanks Brian! Really cool video by the way, keep them coming! :8:
Anymore comments from .30 cal owners?
#1 880-900
#2 150 bar that setting is needed to push the JSB at that speed and have the HST set for most efficiency
#3 I don’t know the exact measurement of the adjustment nut but it is very sensitive. I use trail and error.

Drid, a 30 foot per second drop does not mean you are getting 26 shots on the regulator. The gun should have less than 8 fps spread with the optimum at 2-3 foot per second spread. Without seeing the full shot string my guess is you are getting closer to 20-22 shots. The regulator of the R3 .30 is set with the goal of 880-900 fps as per Ed. You will get more accuracy, shot efficiency, less noise and less wear and tear on your gun if you slow the speed down.
