The RCBS Exp-Decapping Unit for .338 Taper (part no. 9828) is a replacement decapping pin sized to this specific cartridge case. It knocks out the spent primer as the case travels up into your sizing die, so depriming happens automatically on the same stroke as resizing. Built from hardened steel, it is meant to take the repeated impact of high-volume decapping without bending or rounding off. Reloaders running .338 Taper through an RCBS die use this exact pin as their spare or replacement part when the factory pin wears out.

Key Specifications

• Machined for .338 Taper cases, so the pin registers correctly on this caliber’s flash hole and primer pocket.
• Made of hardened steel, built to withstand repeated decapping strokes without the pin itself wearing or bending.
• Pops the spent primer free as the case is driven into the sizing die, combining depriming with the sizing stroke.
• Drops into your existing RCBS sizing die as a replacement or spare pin rather than requiring a new die.
• Weighs approximately 0.9 oz shipped, light enough to keep several on the bench or in a range bag.

Frequently Asked Questions

What caliber is this pin sized for? This decapping unit is machined specifically for .338 Taper cases; it is not a universal fit.

Does it replace my whole sizing die? No, it is the decapping pin/expander component that fits inside your existing RCBS sizing die, not a standalone die.
