Chit AMU is notorious for loading hot when I say hot, brass is one and done.. for those of you living under a rock AMU stands for Army Markmanship Unit.. As the story was told to me AMU showed up to camp perry and shot across the course the long line load was 80gr smk loaded in lapua brass. Well amu was just leaving it lay guys started picking it up as the rest of the story goes the brass wouldn’t even hold a primer.
