The Wilson Bushing Type Full Length Sizing Die. This die will allow you to size the case neck to your desired neck tension along with sizing down the rest of the case body at the same time. Die includes an adjustable depth decapping rod. An extra Decapping Punch is included. These dies do not contain an expander. Made of High Quality Heat Treated Steel. These Full Length Bushing dies mimic the neck sizing of Wilsons' neck sizing dies and are designed to leave 3/16" at the bottom of the case neck unsized, a practice many shooters prefer and find to be more accurate than sizing the full neck.
