The Browning O/U will serve you well. I have been shooting clays every week for several years. I shoot a Fabarms O/U and a Browning O/U for my serious clay shooting. I also shoot other guns and gauges over he course of a year's time, simply because I own hem and want to shoot them. A lot of people get hung up on equipment ( have seen this in a lot of shooting disciplines), at some level hardware will play a factor, but fundamentals and skill sets are more important.
I hosted a shoot years ago, and the fellow who Placed in the top five in a 100 bird shoot was shooting the only shotgun he owned, a old battered Remington 870 pump gun. It was his duck,bird and everything else gun, and he had never shot clays before. Kinda of brought things back into perspective.
