[QUOTE="Pdvdh, post: 364111, member: 4191"] You ever honed the neck out of a hardened resizing die? If so, how did you go about doing that? I just spent four evenings honing out the body of a RCBS full length resizing die so it wouldn't work my brass so much. I used a brass bore brush wrapped in 3M Wet-Dry sand paper, turn by a battery operated drill. All that did was polish the die surface. Next I tried a coarser grade of 3M Emery Cloth. More polishing. Next I coated the Emery Cloth with some silica carbide valve grinding compound - 280 grit. This started to remove some of the hardened steel - painfully slowly. Then I applied 120 grit silica carbide valve grinding compound. After about 2 hours of lapping with the battery powered drill, I was able to remove about 0.002" over the sides of this FL resizing die. Anyone that says you have to clean your brass cases carefully so as to not scratch the resizing die is full of it as far as I'm concerned. Once those reloading dies are heat treated, they are tough - tough - tough. This leave me wondering - what type of machining equipment or tools are used to open up a heat-treated neck on a full length resizing die? [/QUOTE]
