I also prefer the Magtech brass hulls, and mine are the old ones, that use Berdan primers. Loading shotgun shells just can't get any easier than with the brass, and they look great as well. AA's work good, but after a few loadings with black powder, the inside gets rough, presumably the plastic is melting a little bit when fired.
My favorite load with either is 90 grains of FFg, a fiber wad dipped in melted lube but not soaked, and 1 oz of shot. In the brass shells, a 10 gauge card wad pressed in with a dowel seals it just fine. No glue or anything else. They make a lovely boom, and the shot gets out there fast enough to occasionally allow me to break a clay bird or two. Wing shooting is not one of my best skills!

P.S. In the days of muzzleloaders, the old-timers said, "Lotta powder, little lead, shoots far, kills dead."
