Finally got my 2200 up and running but...New valve and new cup but only shooting CPHP 14.3gr. at 450fps at 10 pumps! What should I do now, maybe a new hammer spring?

I’ll check later, I thought since it’s only doing 450fps it was dumping all air? I’ll check though.
Thanks

if dumps all air, you need more. Remove all pump head space if possible or larger valve volume with more pumps.

One more thing, what kind of oil do you guys use for the wiper and the cup? The 2200 of course.

Pump it and take a shot. Cock the hammer and pull trigger a second time. Did it just bounce an empty valve or POP?
If you have air left over after a shot with 5 pumps, it is a weak hammer spring or restricted port.
If you get to 20 pumps and it is still dumping all the air on the first shot, you still have a pump problem.

I guess you guys are correct, I tried another new valve and new cup just to check. Now up at almost 460fps. That's about all it can do!
