Yesterday was my first time shooting Sporting Clays and damn it was a lot of fun. I hit 17 out of 25, the first time I ever shot that sport. When I used to be on a shooting team I was garbage at Skeet, only hitting about 15 of 25 on a good day. Trap I did really well, always hitting more than 21 clays each round, had a few perfect rounds before too. What choke should I be using for Sporting clays? I didn't switch out chokes yesterday when I went from the Trap range to the Sporting Clay range and I had a Improved Modified I believe (didn't pay much attention the first time I put it in)
