Full length resizing some new Norma .222 Remington brass yesterday. I am getting a "scuff" mark around the entire shoulder at the very bottom of the neck where it meests the shoulder. The mark is uniform and is about a 1/16" wide ring. The shoulder is also bumping back more noticibly than on Remington brass, but the Remington is once fired. I also noticed the rim is slightly thinner on the Norma.
Dies are brand new Redding dies that I disassembled, cleaned out with break cleaner and lubed the inside and expander button with case lube per the manufacturer's directions. Any thoughts?
