Black Hills brass is made by Winchester IIRC and is top notch. I typically get 5-6 reloads for match before the cases get used for hunting or plinking. BH also has major military ammo contracts such as the MK 262 Mod 1 and they sell heavily to LE, hence the lack of commercial availability and frequent appearances in the gun rags.
Jeff Hoffman is LE himself so that's where his priority is, which is to make excellent ammo before profit. BH is simply outstanding ammo! In fact I prefer it over Federal GMM. If your LGS doesn't carry it then bug them until they do!
