Unless I'm loading for a wildcat cartridge, I prefer to buy Lapua, Norma, or Winchester/Olin virgin brass with the correct headstamp if I can get it. The only regular production cartridge that I reload with brass that features incorrect headstamps is the 260, as Winchester/Olin has never made 260 cases, so I've used Norma and Winchester/Olin 243 brass to form 260 cases.
