Sorry to hear your troubles with such a fine shotgun. I’ve had a few Perazzi’s. Never had any issues you describe. When I slowed down I was shooting a Caeser Guerini
Still shoot with it some. Had other high end trap guns as well. Your experience hasn’t been the same as mine. To be fair in comparisons though the hulls I used and still have drums of are older production. Unlikely I’ll ever have need to gather/save additional hulls for reloading. Things do change and my knowledge may be dated. Wish you and the OP well going forward.
