I re-tuned the .22 Veteran a couple of nights ago. I've always wanted to tune the Hades 15.89gr below 900 FPS but when the .22 was my only gun, for some reason, I just wanted it to stay at least 30 FPE. Arbitrary, I know... but here we are. Also, not that I was having i accuracy issues shooting them at 915 FPS, but I also want to reduce the FPE since this is my backyard varmint rifle. Now that I have the .25 Veteran, I don't feel as compelled to keep the .22 at a certain FPE.
I pulled out the Huma reg to change it. The last time I changed it, I didn't have a reg tester yet and I set it according to the sticker indicator on the side. I know the sticker is not accurate but I had to go by something. Sure enough, what I thought was 95 bars according to the sticker is actually 105 bars. From my testings previously, I set the regulator to 88 bars to achieve the velocities I was after. At this regulator setting, the highest velocity possible was 900 FPS. I then adjusted the hammer spring tension to achieve 883 FPS average.
