Try a little less hammer strike to lower the first shot and raise the second shot.... assuming the second shot is dumping all remaining air?....

Yes, the 2nd shot is the dumper.

With the rva out any further, velocity on the first shot starts to wander. It's not by a lot~ 40-60 fps. I'd much rather have the consistency on the first shot. Could probably cure that with a different hammer spring...

Noticed the 2100 hammer spring is larger diameter than the 13-XX and Disco hammer springs. It's not by a lot- the step on the front of the rva still holds it fine, and no problems with it in the hammer end either.

I'll get it out Friday and see if I can back down a little more. I actually like where the rifle is performing now.

Nice performance! My 2200 tube and pump linkage just came today. Will probably be awhile before I get to work on it, but looking forward to it!
