Very few Olympic class clay shooters use Browning shotguns, and even fewer win medals with a Browning. Those in the Olympics that have won medals with a Browning have won with a custom Belgian made Browning, not a Miroku made Browning. But that doesn't mean that much idolized Miroku made Browning O/U shotguns are not good. So, I'm not so sure that the fact that no top shooters win with a CZ is relevant to your question, gerrym526.
Where I shoot, there is a guy with a 3 year old CZ Canvasback that he uses almost every week for 2-3 rounds of trap. I asked him about the gun. He told me it has seen around 5000 rounds so far and asked me if I wanted to shoot it. I took him up on his offer because I was interested in buying an O/U that wasn't $2400. The CZ was still tight and solid and shot just fine, and was a huge upgrade in "feel" over my semi-auto. The Canvasback is a $700 gun and is much better than any other $700 O/U I've seen, i.e. Stoeger, Stevens, Mossberg, and Tristar. I was willing to spend a bit more than that so I landed on the new Franchi Instinct L, which has a case hardened steel receiver (which would have a longer lifespan than aluminum) and is made in Italy. It's $1100 and has very nice walnut, nice machining, very good looking polished blue barrels, and good feel for the price. It is definitely a step up from the CZ O/U and saving up for the $400 price premium over the CZ is much easier to do than finding the extra $1700 to step up from the CZ to a Silver Pigeon. And, by the time you get really good at trap/skeet/sporting clays with an all purpose field-grade O/U like the CZ or Franchi (something I haven't quite done yet), you'll know what you want in a dedicated trap or skeet or sporting clay gun in terms of length of pull, comb height, drop-at-heel, rib height and other fit criteria. But you won't know what you want or like in a gun until you get good enough to be able to tell the difference. In the meantime, why drop over $2000 on a gun now that you could decide isn't the right gun for you anyway once you're good enough for the little details to matter to your game? There are very good trap shooters at my club that would have strong but differing opinions about a $3000 Browning vs a $3000 Beretta, but the differences are lost on somebody like me who isn't good enough to tell the differences yet. But when I CAN tell the difference, I don't want to already have spent a lot of money on the wrong gun.
