RCBS 325 WSM Full Length Reloading Die Set

The RCBS 325 WSM full length reloading die set is a two-piece solution for anyone loading bottleneck rifle cartridges on a progressive or single-stage press. If you're building precision rounds for your .325 WSM rifle—whether you're handloading for a custom bolt gun, a newer Winchester Model 70, or any other platform chambered in this efficient magnum—this die set gives you the essentials to resize fired brass and seat bullets to exacting standards.

The full length sizer die is engineered to bring your fired cases back to SAAMI minimum dimensions, which means your rounds will chamber reliably and headspace will stay consistent from reload to reload. The die sizes the case body, deprime the spent primer pocket, and expand the neck in one stroke. RCBS designed this die with air vents to protect your brass from the pressure spikes that cause damage when air gets trapped, and the vents also help excess lubricant escape so you don't end up with deformed cases.

The included seater die handles bullet seating and includes a built-in roll crimper, so you're securing the bullet in the case neck at the same time you're seating it to your target depth. That combination saves you a step and promotes consistency across a full batch of reloads.
