In 40K rounds a brand new Browning O/U that was too tight to cock when new, will be too loose to safely shoot. And that's a modern gun in most respects, with an optimized design, modern machining, and modern alloys. It'll shake like a RRL.
I agree 100%, but we're in the minority in that opinion, CZ. That is the modern O/U that is the
most likely to shoot loose among all the most popular ones for clay target shooting sports. I have seen it over and over, with shooters who care for their guns ...... clean them religiously and keep them lubed. I can't tell you how many I know of that began opening the top lever upon firing the first shot. I have seen them with rubber bands around the top lever and action to help keep this from happening. And, these are guns owned by regular Joes, not pros who put 50,000 rounds a year through them. I know one sporting clays shooter, who competed a lot with Brownings, who owned two exactly alike. One would be in the shop being refitted while he shot the other.
My theory is that part of the reason Brownings are so prone to this wear is the height of the action, putting the barrels higher above the plane of the hook and pin than so many others. This "extreme" distance from the plane of the hook/pin to the plane of the top barrel especially, gives the recoil greater leverage to try and defeat the bolt, causing it to have a greater tendency to open itself. But, I'm no engineer, just a shooter/competitor/hunter, and I could be all wrong with that theory.
