The 100fpe quest

I decided a little while to get my Sumatra back to factory(spring wise) & try for a 100fpe. The rifle had already had some mods done to it, valve stem turned down, tp drilled out, barrel port drilled & side of the valve machined flat. The other day after I got a hammer spring I put it back together & put some 45gr slugs over the chrony. At 200bar, 45gr slug & im gonna call it low power, cause it’s on the black dot for the 2nd time. I got 969.9fps for 94fpe, today I put some 48gr slugs over the chrony & got 970fps for 98fpe on high power(red dot). So close but air consumption was crazy. So I need to back low power & work from there. Any ideas on what else I could do? I maybe able to take the barrel port & little bigger. When I get another chance I’m gonna put some 55gr slugs over the chrony.

Scratch this. The 55gr slugs on low power made 106fpe. Decided to zero the rifle, on the 4th shot the poppet crapped out & started leaking. So now begin the search for a poppet. 🤬🤬🤬
