you can do this but it is prolly the noid getting to much pressure
relube the bolt and set the reg to 0psi
slowly raise the pressure while walking the trigger (eyes off, no paint, air on) eventually it will leak, seal and then fire. It should shoot fine after that but if it does not then you might need to rebuild the bolt with fresh orings and relube the noid.
edit: sleek will work very well
