Bob ,at full coil bind the second string was near identical only I gained 5 FPS at the peak. I think I only gained dwell time which did basically nothing due to restriction in flow.
Finished up the stock and cut some groves in the action to fit some FX no limit rings . Now it’s ready to go hunting .
I’ve been trying a couple different spring combos but my velocity is way too slow at 190 bar . I’ll get there just need to play with it a bit more . Still trying to figure how to incorporate a cobra cylinder . Hope To see JSAR make an SS valve . That would kill two birds at once .
