Tuning AGT vulcan 3 Long, .30cal Regulator pressure, tuning

[30vulcan2]

Hello!
I have a new rifle and was wondering what your regulator settings are for the .30Cal.
How many shots you make per fill?
What bullets are you using and what velocities are you getting?
Are you made some tuning?

Thank you

108 bar shoots a 55gr slug at 870 fps

120 bar shoots 55gr slug at 915 fps.

198 bar shoots a 70gr slug at 960 fps.

Shots per fill ~ I don’t know actually. At 108 bar, I’d imagine 70 shots. At 120 bar, maybe 55 shots. At 198 bar, 15 shots.

That’s not relevant unless you have the same barrel I do. Mine is an early V3 with a Russian Alfa Precision barrel.

With that said, AVS slugs of .3063 diameter dish base.

Did you turn the regulator to 198 bar? I turned mine 1/4 turn to the left and i have another hamerspring inside. The .30 is set out off the box at 170 bar i heard. Now the 54.5 grain Zan slug does 300 msec.
Vulcan 3 .30 700mm cz barrel. Next week i test the accuracy at 100 meter again.

Yes, I’m a tuner and have a reg tester.

Thanks for the answer. How much did you turn the regulator?

All a a bit different bud. In general, if you make a mark on the reg’s adjuster and make a 12 o’clock, 9 o’clock, 6 o’clock & 3 o’clock on the body of the reg; treat the mark on the reg’s adjuster as a minute hand. Turn CCW 5 minutes to increase 10 bar.

Thanks, that will help.

This morning i measured the regulator and now it is 195 bar. With the original hamerspring i get 293 msec and with a bit Heavyer spring exact 300msec with the 54.5 grain Zan slugs. This week i test this setup at 110 yards.
