Reliable, generally hot for caliber, tough as nails brass with undersized primer pockets.
Nothing wrong with the ammo at all. For many calibers, as I mentioned, you will find that it's like most European ammo in that it's on the upper end of power for a given caliber vs. American ammo(broad generalization). I've shot it in 25 auto, 32 S&W long, 9mm 38 special, 357 Mag, and 44 Mag. They do make a great(and not hotly loaded) 38 Wadcutter.
I don't like the brass for reloading as I find it has a fairly rough "feel" on the press and-as I mentioned-I find the primer pockets tend to be tight. I keep meaning to buy a carton of S&B primers. With that said, I've never lost a case. If you don't reload, that's not of much concern to you.
You have to check caliber by caliber, but a lot of black box Herters(Cabelas house brand) is made by S&B.
