ok heres what I got, Palmer Reg, NDZ valve, spring kit, stock bolt, 15degree assault block VA.

I cant seem to get my velocity under 300fps. I have tried, a light valve, med main, strong main, weak main all with no luck. I tried a strong valve and med main and nothing. Normally I use a light valve and a med main and im good to go. Any ideas of a spring combo to bring it way down.??

I ran out of air but was going to try the stock valve spring and a light main?? any thoughts , ideas.........HELP

Try lowering your pressure a little.

thats the thing, I got it at 225-250 psi depending on what spring I got in there and its not any lower ;(

Heavier valve, higher PSI input (up in the 300-450psi range, or higher most likely), lighter main spring. Those'd fix your problems.

so its a combination of the springs and the lower psi it is not making the valve close fast enough bc there is less pressure??

Most likely...seems your getting too much dwell. What striker are you using? Also try firing with your striker spring guide removed and see if that drops your FPS.

Are you using Co2 or HPA?

ok well I got it to shoot 285 fps, I put in my stock valve which is really stiff and I have a weak main, reg. is at 300psi. How can I lower it jsut a bit more, my field shoots 270. Cut the spring a bit? Spring guide is removed too!!
