I purchased a few hundred rounds of (supposably) once fired LC 5.56 brass a couple weeks ago. Turns out that about 1/3 of it had been reloaded, so while working up the stuff that wasn't once fired for coyote hunting, I ran across a few pieces like the one in the pic below. Any idea what caused the axial lines that run half way down the case? I don't plan on loading them, but just curious as to what caused the lines. it's an LC 09 without the nato cross.
