I am looking for a O/U shotgun to shoot ATA trap, doubles and next year try International Trap. I’ve been looking at an assortment of brands and models and have a few questions from those who shoot regularly. What is the difference in design between a “Sporting Clay” and a “Trap” unit? Is it the drop of comb, barrel configuration, or what? Should I look at only a Trap gun or can a Sporting Clay do the same? Then we come to barrel length. ATA trap shooters have told me to go to a 32” barrel. Fine but is this to long for International?
