RCBS Carbide 3-Die Roll Crimp Set .357 Mag/.38 Spl

RCBS Carbide 3-Die Roll Crimp Set for .357 Magnum and .38 Special

This is a complete reloading solution purpose-built for straight-wall pistol cartridges. RCBS engineered this set specifically for shooters who demand consistency and reliability in their handloads.

What's Included

The set contains three precision dies, each designed to perform a specific function in the reloading process:

• Carbide Sizer Die — Resizes the case to proper dimensions and removes the spent primer. The carbide sizer ring eliminates the need for case lubrication, saving time and reducing mess.
• Expander Die — Opens the case mouth to the correct diameter for bullet seating and imparts a slight flare or bell to the case mouth. This flare aids in bullet alignment and feeding.
• Seater Die — Seats the bullet to precise depth and applies a roll crimp to secure the bullet firmly in the case.

Why This Matters

The carbide construction of the sizer die is a significant advantage. Unlike conventional steel dies that require lubrication, carbide dies allow you to resize cases dry. This means fewer prep steps, less cleanup, and faster reloading sessions without sacrificing accuracy or case life.

The roll crimp is the preferred method for revolver ammunition. It provides a secure mechanical lock that prevents bullet setback during firing—critical for magnum loads where pressures run high.

Ideal For

Revolver shooters who handload for .357 Magnum and .38 Special. Whether you're loading target rounds or defensive ammunition, this set delivers the precision and reliability you need.
