LC Brass Question
I got ahold of 100 pieces of what was advertised as "new" .308 brass that is supposed to be Lake City Match It has LC MATCH headstamp with manufacture year (not all the same year) Question is,,, each case has a small rippled machine mark (a set of small vertical lines, side by side, going around the case body about 3/8ths inch above the case head), and I see no indications of any annealing iris that is usually visible in once fired Lake City brass. It is supposedly new, but I thought the annealing iris would be there even in new brass, and I don;t think I've seen this set of little vertical lines that go around the whole case before.
Anyone out there have/seen any new LC Match brass,,, any experience with it? Did I get a bad buy,,, some knock-off copy?
