I'm extremely curious to see chrono data comparing the two in the same gun. I have both kits for my .22 RWS 34, but no chrono.
A, I like having spare parts, and
B my goal is to settle on an ideal compromise between power and noise. I like to tinker. I have four different seals too. I'm thorough lol.
The vortek PG2 was installed first with a green Apex seal. It was softer than the other seals so I though it would be a good choice since I didn't want to size it. But I over lubed it with vortek's awful moly looking stuff. I was curious about the tesla seal, so I tore the gun down and cleaned all of the lube off, and put a light shmear of macarri's moly on the piston housing and spring only. The gun has settled into a nice enough shooter that I don't really want to crack it open until something breaks, so macarris GRT MK2 kit lies dormant. I don't have any idea what my gun is doing velocity-wise. The gun is very quiet for what the pellets do down range though. I'm always thinking about more power, max efficiency, so I'm dying to compare them-for SCIENCE. If someone in southern colorado has a chrono and the willingness to have a stranger with a gun visit them, I'll test them back to back and post results here.
Would a paintball park let me use theirs? hmmmmm
