To the best of my knowledge none of the big companies has offered 7's in my lifetime---a LONG time. You can buy 7's in Gamebore (English 6's) and, I think, RST's. If you handload Ballistic Products sells both lead and nickel 7's. I use lots of 7's, my favorite shot size, our local Sportsman's Warehouse usually carries them in lead. Must be wanting what you can't get, I used to shoot 3's and 1's for ducks/geese in the good ol' days of lead. Come to think of it, I still do in Steel and Tungsten Matrix.
