I was really surprised about people not using #9 shot. After all, in skeet you are shooting at targets less than 25 yards away. As for 7/8 oz loads, it is true that one probably wont find them to buy all that easily. So, I guess you have to reload to be sure of getting them, as has been said. But, if you are reloading, or you get lucky when you are shopping, there are a lot of reasons to use them. Less recoil and more efficient, for example, and I haven't felt that I have lost a bird because of #9 yet. Actually, I have many other ways of missing and 7/8 oz of #9 patterns very well at the ranges involved. Really, anything over an ounce of shot has to be overkill in skeet, at least it sure feels that way to me. As for 7/8 oz of 7 1/2 shot, you're right CR it works, but I just felt funny using it

...go figure.
