I'm using 0.3 x 0.045 x 1.5 spring now with less spring binding.

That's a strong ass spring ya got going on there screwwork. That's the same spring the guy at HiPac sends out as a 3kpsi upgrade. Heck I can't cock it in any my 22xx based guns with that spring installed. Never tried one in my prod yet. I'm good with the .3x.041x 1.5 in all my air guns. I took my tranfer port out to 1/8" that juiced it up enough for the back yard.

Thx for the info milksatx :D
Your right, I was looking at what I did to get to 25 Plus fpe and not thinking about 20 fpe as Invisible Hand was referring to.
