RE: What kind of shotgun shells for skeet????
Try a 1 1/8oz load with 8 or 9 shot. Probably the best way to find out if it'll work ok in your gun is to buy a box and test them at the range.
It's been a long time since I shot skeet, and when I did it was with a pump gun (870). Teaches you how to handle a pump really quickly.
