Bought some of the 20 round PD HST (180gr .40) and then stumbled upon a couple boxes of LE variety in the 50 round boxes. Noticed the more expensive 20 round PD rounds were all shiny and new looking while the 50 round LE were pretty rough looking; a few dents on the case, brass showing through the nickle plating, black crud here and there. Is this typical of PD vs. LE production? Factory seconds maybe?
