I have an '03 model TES, which is stock except for hpa and a teardrop barrel. I've been running it at around 425-475psi, but after going through a few searches, it seems that some people can run them in the high 200s and still get 250-260 fps on a chrono. I want to be shooting between 275 and 290 fps, so where should I set it?

psi is used to adjust velocity so it depends on what ur feild runs just dont set the psi over 400

Yeah my field has a limit of 300fps, so I want to be in the 275-290fps range. Where should I set it? Right now it's a hair past the 375psi mark.

if u put it down that much u are not going to get the same fps!! u would have to use a hard main spring and maybe get a higher flowing bolt

I just ordered a tiger shark bolt, so I'm just going to leave it where it is now. It's about a third of the way between the 375 and 500 mark, let me know if I should adjust it at all for the bolt.
