RCBS 6.5X47 LAPUA Neck Die Set – Group D – Bottleneck Rifle Cartridges for Bolt-Action Rifles

The RCBS Neck Die Set is a specialized reloading two-die set designed for bottleneck cases to be fired in bolt-action rifles only and is recommended for cases fired out of a specific rifle and neck-sized to go back into the same rifle. The Neck Sizer Die Set consists of a Neck Sizer Die with an Expander-Decapping Unit and a Seater Die with a Bullet Seater Plug. The Neck Sizer Die resizes the neck only without touching the shoulder or body of the brass casing. This ensures a precise and consistent amount of neck tension which can improve accuracy and consistency when using brass that has previously been fired out of the same rifle. The Seater Die is used to crimp and seat the bullet to the desired depth and it includes a built-in roll crimp feature to secure the bullet in place. This can be especially useful for some rifles and shooting applications where reliable feeding and consistency in cartridge length is critical.

Full Length Sizing Dies: Resize the entire case to SAAMI minimum dimensions; best for reliability semi autos or brass used in multiple rifles. Neck Sizing Dies: Resize only the neck; reduces the chances of case head separation and can improve accuracy in bolt action rifles fired in the same chamber. Small Base Dies: Resize slightly more than standard full length sizing dies; ideal for semi autos or tight chambers where feeding reliability matters most. More Questions?
