I see you have a psi gauge on it. What psi is it producing at those power levels? I like your trigger idea! What vavle work have you done?

The gun with a gauge is my G2 which stands for gauge and grenade as it has a grenade bolt.

It has a 66 pump tube, 766 pump link, FT piston and valve, Challenger barrel, 1701 trigger group.
The valve has a Delrin stem, ported .157" port, light valve spring,
10 pumps registers 1550 psi on the gauge at 750 FPS with 7.9 grain CPHPs.
I use 9.57 grain H&N Barracuda Extreme pellets exclusively for hunting and pest control.
That gun is my most accurate gun. Bagged 110 fox squirrels with it last year.
