RCBS Small Base Sizer Die Set .223 Remington

RCBS Small Base Sizer Die for .223 Remington

The Small Base Sizer Die is engineered specifically for reloaders working with semi-automatic, pump-action, and lever-action rifles chambered in .223 Remington. This specialized die addresses the tighter chamber tolerances found in these firearm types.

How It Works

Unlike standard full-length sizing dies, the Small Base Sizer resizes cases to dimensions below SAAMI minimums. This precision approach reduces both the shoulder and body diameter by a few thousandths of an inch, ensuring reliable feeding and chambering in firearms with tighter tolerances.

Key Features

• Precision Engineering: Crafted from durable steel with exacting tolerances
• Integrated Expander-Decapping Unit: Removes spent primers while preparing cases for reloading
• Proper Case Preparation: Sizes bottleneck cases to exact specifications
• Included Storage Box: Keeps your die organized and protected
• Lifetime Guarantee: Backed by RCBS's 60+ years of reloading expertise

Important Note

This die is specifically designed for semi-automatic, pump, and lever-action firearms. It is not recommended for ammunition intended for bolt-action rifles, which typically have looser chamber tolerances and do not require small base sizing.
