Redding 20 Caliber Carbide Sizing Button Kit (47203) .204

Description

If you've been fighting sticky, grabby neck sizing on your .20 caliber brass, this is the upgrade that quietly fixes it. The Redding 20 Caliber Carbide Sizing Button is a drop-in replacement for the standard steel expander in your Redding dies, swapping it out for a polished tungsten carbide ball. That carbide surface glides through the case neck with far less friction, which means you can skip the inside-neck lube step and still get a smooth, even pass every time.

How the Redding Carbide Size Button Works

The real trick here is the design. The carbide button free floats on the decapping rod, so instead of being locked in one spot, it self-centers in the case neck as the case travels up the ram. That self-aligning action helps produce more uniform neck tension and keeps runout in check, which is exactly what you want when you're chasing tight groups with a .204 Ruger, 20 BR, or any other 20 caliber wildcat. Because carbide is so hard and slick, it also resists the galling and buildup you can get with a bare steel expander dragging through dry brass.

Fitment for Your 20 Caliber Carbide Sizing Button

This kit is built specifically for Redding dies, so it's meant to drop into Redding Standard and Type S neck and full length sizing dies. It is not intended for use in dies from other makers. If you're already running Redding gear, installation is straightforward and you'll have a cleaner, faster sizing process the next time you sit down at the press.

It's a small part that punches above its weight. For high-volume reloaders and precision handloaders alike, cutting out the lube step and gaining more consistent neck tension adds up fast over a loading session. Redding's reputation for tight tolerances and lifetime-grade machining carries right through to this little carbide ball.
