Is it normal to hear the plenum refilling with air after taking a shot? I can hear compressed air flowing back into the plenum, lasting a few seconds then goes away as the reg closes up.
I have a Gen 1 Impact X, .22 cal with the standard 20mm valve tube (not power plenum). Shooting 18.13 grain JSB’s at 880 fps, with RP set at 105 bars.
