Default Mk4 gp velocities

Hi there,

don't know if anyone can help - my gp only goes up to 785 fps (although it shows rite up to 999 on the info screen) I'm happy with the 785 for using 8.4gr pellets but when I was trying some various 7.9's it still won't let me up the fps to 815-820! Which means I'm only getting just over 10ftlbs! I no this is obviously a safety feature to stop heavy pellets a high velocities, but is there anything I can do to up it slightly for using the lighter pellet or is it just a case of having to stick to 8.4's if I want 11.5ftlbs???

Any info would be gretly appreciated

Regards Robert
