RCBS 44-40 Win Roll Crimp Reloading Dies Set$74.38
Availability: In Stock
The RCBS 3 Die Roll Crimp Set for .44-40 Winchester is purpose-built for reloaders working straight-wall cartridges like this classic pistol round. Whether you're loading for a period revolver, cowboy action shooting, or hunting, this three-die set handles the complete cycle: sizing, expanding, and seating with an integral roll crimp to lock bullets firmly in place and prevent the movement that can cause reliability issues downrange.
Roll crimping is the traditional method for straight-wall pistol ammunition, and this RCBS set does it right. The hardened steel Sizer Die reduces fired cases to proper dimensions while removing spent primers. You'll need to lubricate your cases for this step—a small but important detail that ensures smooth operation and case longevity. The Expander Die opens the case mouth to the exact diameter needed for bullet seating and creates the slight flare that aids feeding through your cylinder or magazine.
The Seater Die performs dual duty: it positions the bullet at the correct depth and applies a controlled roll crimp that grips the bullet securely without deforming it. RCBS dies are machined to tight tolerances, hardened, and finished to exacting standards—the kind of precision and durability that keeps reloaders coming back. Made in the USA, this set arrives in RCBS's familiar green box and integrates seamlessly into any progressive or single-stage press setup.
