I was resizing some brass tonight, and noticed the FL resizing die was leaving a sharp scored edge right at the bottom of the bottleneck. I first noticed it on some nickle cases I was resizing, and now have 20 with a nice, shiny brass ring on them. I took the decapper out, marked a couple of brass cases with a Sharpie, and ran them through. The score mark is only halfway around the neck, with a couple of smaller ones on the taper. I looked inside the die, and there is a small edge in that area that wasn't polished off during machining. I have some valve grinding compound, jeweler's rogue, and a full assortment of sandpaper all the way down to 10K grit. Would it be better for me to attempt it myself, or contact Lee and sideline my .223 for a bit?.
