It's all a balancing act to get consistent shot strings for whatever pellet/slug you're trying to shoot, and the speed/power you are wanting to shoot them at.
To learn how a PCP works and understand concepts like reg pressure and hammer spring tension you'd need to dedicate some serious time with a single gun, vs your typical pattern of "reviewing" guns that you don't really know much about. Not trying to ruffle feathers here, just calling a spade a spade. But seriously, a chronograph, some meticulous notes, and a lot of pellets over that chronograph would really help your knowledge base, which would in turn greatly improve your reviews. The basic concept is to make a single change and then see what effects that change has, record results and go from there.
Thank you! That totally answers my question. I wanted to know if I had to do the "balancing act" thing...I was afraid having 2 adjustment knobs meant that.
On my channel I test guns "out of the box". I don't have the patience or time to tune the guns. I would love to understand how the balancing act works, but I can't really get into it with guns I review. I'm not AEAC, getting paid $3k per video. I can't even afford pellets: another big reason you won't find me tuning guns. The whole process sounds horrific to me. I'll gladly pay an extra $2k for a gun that's already tuned.
Any gun where I have to turn dials and experiment to get to shoot accurately, I have NO interest in....and that includes the Hatsan Factor of which I just bought 2. Lets hope Hatsan tuned it at the factory!
