Nice gun Thor. I have a 12 ga White Lightning and shot that in trap leagues and some recreational skeet and sporting clays. Your's will probably weigh 8 lbs give or take a few ounces, so it's not a light gun. I shot 1000's of 1 1/8 oz factory or reloads that were 1145-1200 fps. As I've gotten older I've been reloading more 1 oz loads (~1180 fps or so). They have noticeably less recoil. You can usually find 1 oz loads if you shop around. Many reloaders have been shooting 7/8 oz loads also. Again, lower recoil--and lower cost, too.
Have fun. Your gun will last forever.
