Frankford Arsenal X-10 .243/6mm Caliber Conversion Kit

Description

Running a lot of .243 Winchester or 6mm on your Frankford Arsenal X-10 progressive press? This caliber conversion kit is how you set that machine up to feed and seat those rounds automatically. It bridges your X-10 Rifle Bullet Feeder Collator, which is sold separately, to the press itself so bullets drop in place without you having to hand-set every one.

The heart of the kit is a caliber-specific micrometer-adjustable seating die assembly, and it comes with an on/off switch so you can pause feeding mid-session without breaking everything down. The micrometer gives you seating depth adjustments in .001 inch increments, which makes dialing in your overall length a quick, repeatable job instead of a guessing game. Once you find the sweet spot for a particular bullet, you can come right back to it.

What the X-10 .243/6mm Kit Brings to the Bench

The clever part of this setup is how it integrates into the X-10 tool head. The bullet feed system feeds and seats bullets in the same station, which frees up a separate station for a crimp die or another operation like a powder check. On a progressive press, every station counts, so getting two jobs out of one is a real efficiency gain when you're cranking out volume.

Getting Your X-10 Set Up for Rifle

This is purpose-built for the .243 Winchester and 6mm family of cartridges, finished in gray to match the rest of the X-10 ecosystem. Keep in mind the collator itself is a separate purchase, and this kit is what makes it talk to the press. If you're already loading rifle on the X-10 and want to take the manual bullet placement out of the equation, this is the piece that gets you there and keeps your sessions moving at progressive speed.
