Elh, just picked up a new Royale a couple days ago. Mine is still locked into place at 4.45mm. Shooting jsb 18's at 910 fps.
Quick question if you happen to know....what was the factory reg set at on yours? And what did you decided to run the huma at?
Thanks
Let me see if I understand. Are you saying the adjusting nut on your hammer spring is 4.45mm below the receiver surface? If so, that is0.175". I think mine is in that range, can't measure without removing the locking/jam not I added. I have no idea of the factory reg setting, as I do not have a reg tester. And frankly, I'm not sure the techs at FX know either. I never received a clear answer. What kind of ES are you seeing in your chrono runs? Ultimately, it's a matter of balancing the reg pressure with the hammer spring tension. My velocity is in the 880 range, so, I guess my reg pressure is little less than yours. The Huma pressure is around 140 BAR on the Huma scale, but I'm not at all sure that is accurate, in fact, I'm pretty sure it's not.
Correct. Below the receiver.
The huma i had in my Wildcat was within a couple of bar of the gage i had installed. So at least that particular reg was marked pretty close.
I like to find out max velocity for a particular reg setting. Then back the velocity down by 3 to 5% for best efficiency.
So far on a few 10 shot strings with only about 50 or so through the gun, im only seeing an 8 fps extreme spread. So far so good.
Im liking this rifle way more than my Wildcat. And may have bumped my daystate regal down a notch as far as an easy to shoot well rifle goes. And i didn't think that was possible.
