In my lowly understanding of tuning a PCP I've been informed that you want to have the HST at roughly 95%-97% of the plateau or max velocity that you can get at that reg setting. Start slow and keep turning up the HST until velocities stop climbing and then back it off 3%-5%, easy peasy.
My question is this...once that harmonious balance is achieved between reg pressure and HST it doesn't matter what projectile I shoot that balance will always remain, yes? For example, my 22 grain slugs were peaking at 1050 fps so I backed the HS down until I was achieving 1000 fps, 96%; balance achieved.
Then, I decide to shoot some 26 grain slugs at this same tune and they only hit 945 fps...however, am I correct that my tune is still in balance?
