I use my hammer spring adjuster on my crown 25 cal. I have the regulator up to 140 bar and hammer spring adjuster to max. It’s shooting the 34 grain jsb at 850 fps. That’s 54 fpe. When I want to shoot the 25.4 grain jsb I put the hammer spring on 4 shooting around 890 fps. I get 50 shot with 34 grains and 60 plus with 25.4 grain.
