Neck sizing extends case life over full length resizing, and improves accuracy by eliminating variables. The only drawback is that the brass must be used in only the firearm that originally fire-formed it. A collet in the sizing die squeezes the case neck against a precision mandrel for a perfect bullet fit with minimum bullet run out.
