Remington sub-sonics are advertised at 1049 fps but chronograph 864 fps in my gun. CCI std. vel. advertised at 1070 fps chronograph 1008 in my gun.
CCI will cycle the action every time. Rem. SS will only cycle the action on the first shot realiabily.
Anybody else had this problem? The chronographed velocities are without the suppressor installed. Even with the suppressor installed, the Rem. are not reliable.
Has anybody replaced the recoil spring with a lighter spring or cut coils off the factory spring?
