Just picked up a Wildcat MK3 in .22 which has some odd sounds. Most every time I break a shot there is a bouncing / rattling sound in the action close to my ear. It is the same on all 7 hammer settings. However, sometimes it is quiet and just goes thump like a well tuned / harmonized rifle. The rifle arrived with the reg set on 100 bar and is 100% stock. Just wondered if this is the norm with WC’s?
