Hey reloaders, if you're looking to get more life out of your 7mm Rem Mag brass and maybe tighten up those groups, this RCBS neck sizer die is worth a look. It's part of their Group A series and it only sizes the neck of the case – it doesn't touch the shoulder or body. That means your brass stays fire-formed to your chamber, which usually leads to better accuracy and way longer case life since you're not working the metal as much every time. It comes with the expander-decapping unit installed, so you can deprime and size in one step. The die itself is solid steel with a smooth finish, and it threads right into any standard 7/8-14 press. It also comes in a plastic storage case to keep it protected. Perfect for bolt-action shooters who want to neck-size only. Just lube the necks lightly and you're good to go. A simple, effective tool that does one job really well.
