The RCBS .300 Win Mag neck sizer die (item 15330) sizes only the case neck and decaps, leaving the fire-formed body and shoulder untouched for longer brass life and a tighter chamber fit in bolt-action rifles. 7/8″-14 thread; shellholder #4 sold separately.

The RCBS .300 Winchester Magnum Neck Sizer Die (item 15330, Group A; 3GT code 15526) is a single steel die with an expander-decapping unit that sizes the neck of a fired case to grip the bullet while leaving the body and shoulder as the chamber formed them. Neck sizing suits bolt-action brass that will be fired again in the same rifle: it works the brass less, extends case life and keeps the case centred in the chamber. It decaps in the same stroke. Standard 7/8″-14 thread; use the RCBS #4 shellholder (sold separately). RCBS is distributed in Australia by NIOA and stocked at 3 Gun Tactical, Tingalpa, Brisbane.
When should I neck size instead of full-length size?
For brass fired in the same bolt-action rifle it will be reloaded for. Brass for semi-autos, lever guns or several rifles should be full-length sized.
Does it include a seater die?
No. This is the neck sizer die only; pair it with the RCBS .300 Win Mag seater die or a full die set.
Which shellholder?
RCBS #4, sold separately.
