I had a .22 that would do 9fpe with the very light Hobby pellets, and I thought that was the most one of these little guns would do, the most a .177 would be good for was a bit over 7fpe. Where has that extra power come from? Did you modify the transfer port? Or is that a trade secret?
Im finding it hard to believe that is why i have now bought a new 35s to see what the outcome is with that, im trying to do this before Christmas. I will be having a .22 cal to see what the outcome of that one is. I have not changed the stroke , fitted a V-Mach piston seal. ?
