I got a 3 pound coffee can of 7tc/u brass from a friend.I noticed it was old but decided to resize them any way. I threw several pieces away when I lubed them for various reasons. Half way thru resizing, a case broke off about 1/4 inch in the die. Now I have to buy a tap that will fit in a 223 or 7tc/u case body. The die is a Pacific Dura Chrome die and I'd hate to ruin it trying to chisel the case body out.
All was not lost though! I have an RCBS set that I finished with.
