I am now using my Beretta 303 auto, having blown the dust off. The auto is 1lbs lighter and easier on the recoil, but I am still struggling to do more than 50 without a break. I have tried various cartridges with the exception of Eley. I found the Fiocchi dirty, but they did function OK if I took them to bed the night before using them. I have settled on the Hull, they are clean, work well and operate the gun, OH and I do not have to sleep with them. I have been using my favoured I/C Briley choke in the 28" barrel and am still shooting 75% plus. I am now considering selling the O/U and sticking with the auto.
