It was set at 38 fpe with a 2700 reg setting but shot count was in the lows .. I’ve backed it down to a comfortable 32 fpe (2200 reg and some Hammerspring adjustments)

But she can thump if your willing to sacrifice shot count

It’s a fun gun.
How many shots is a low shot count? I do see you have a big bottle on it. Have you messed with the hammer spring adjustment at all? I feel like you should be getting more speed at a lower reg even with the barrel cut down. My buddies is currently at 850fps with 25gr reg set to 2100, and that was before I put a 500cc bottle on it.

I have adjusted the Hammerspring. It was getting 18 shots with the reg set at 2700.

I backed off Hammerspring 3/4 turn and reg set at 2100 actual. Along with
It’s 220 cc bottle I get 35 shots now at this setting.

(I backed off Hammerspring 3/4 turn and reg set at 2100 actually )

It’s a 220 cc bottle
So I get 35 shots now at this setting

Ohhhh okay, that makes way more sense now. In the picture it looks like a 480cc bottle, not a 220cc. Damn so it's a really short barrel now.
