I recently installed a Huma regulator in my Taipan Veteran Long .22. I set the pressure to 100 bar to shoot JSB 18.1s @ 885 fps.
I now have ~300-400 shots through it since the install, and have experienced some velocity fluctuations early on that I have chalked up to regulator break in. However, I am still not satisfied with the consistency.
1) It seems that I cannot rely on the velocity for a given day. For example, when I last put it away (Monday) it was shooting 885 fps. Today, it settled at 860 fps with no changes. It remained at this speed after 30 shots so I had to increase HST to reach desired speed. It seems that everytime I take the gun out to shoot the velocity has shifted.
2) The cold bore shot is ~25 fps lower than my desired set velocity. It takes 4-6 shots for the speed to settle. I tried to resolve this before by lowering the reg pressure from 115 bar to 100 bar, but I am still seeing these annoying fliers.
Thank you to everyone who has helped out in my previous recent post. I am at the point where I have found the velocity that I want to shoot and am done tinkering with tunes. I just want the gun to deliver my set velocity when I pull it out of the safe. Maybe this is too much to ask for this gun...
