I'm trying to get sub 500! Will valve lock occur if I use the light hammer (42g) and stock Disco spring?

Using a 15.50" Disco tube for a pistol.

Using about 1100 psi.

Thanks

I would say it is very unlikely.... At 1100 psi you could probably use a 22XX hammer spring with that hammer and still be over 500 fps, depending on barrel length....

Sorry..i put the 7" barrel back on. The only other thing I could use is the hammer with the adjustable striker on it. I noticed before that when using that hammer on my rifle as I shot. I took out the hammer and the pin recesed downward by itself and wondered at the time why my fps came way down . So using that hammer could do it with some thread locker, if my other plan doesn't work. It is a stock 2240 hammer spring I would use.

Happy to say working fine no valve lock..2240 stock hammer spring and only 2 CW turns in. chronying to come!

Thanks Bob

Cool project! Will be interesting what kind of shot count you get.

Have you tried restricting the size of the transfer port ?
