This is how my .177 Marauder is set up. My guage block Huma at 1650-1700 psi. Transfer port restrictor open all the way. Hill light hammer, peek striker, hammer spring and valve spring. With hammer adjuster 2 1/2 turns in, I get around 85+ shots at 18.5 ftlbs. Thats a JSB 13 GR going 785fps. 4 turns of hammer adjuster I get 840+fps for 21 ftlbs. With hammer at zero turns, around 10 fpe for around 140 shots. The gun is very efficient and quiet.
