where can you buy 280 brass that is not nickle plated? And why do they Plate it? It seems that there is no problem finding any other cal. in plain Brass. I need to fireform some more 280AI and I do not want to use nickle plated Brass. I found a place on line that advertised 280 Brass. I ordered 600 rounds, when it arrived today I opened the box and it was nickle plated. Whats up with all the 280 brass that is available being nickle plated? You would think the would say it is nickle plated. Any suggestions???
