Most Power in .22 and .25 with wasp waisted pellets?

I’ve got a R&L Hi Flo valve on my rifle. What is the most power I could expect out of this rifle with both a 18″ and 24″ barrel?

I’m currently running 33-34 fpe with a 12″ barrel in .22 using JSB 18.1.

Thanks,

Paul

I have the TT Hi Flo, 18″ barrel in .25 cal.

I can just go over 100fp, using Jerry’s 62gr slugs. But I need to fill to 3200psi and only do it a few shots. Filling to 3000psi, I’m around 94-95fp.

If you want more power..go with the 24″ barrel.
