JRC CUSTOM FULL FORM DIE
Built Specific. Built for You.
$299.99 — Made to Order with a Custom Build
Complete your JRC Custom Muzzleloader Build with a JRC Custom Full Form Die, precision machined specifically for the individual barrel used in your build.
Each die is precision machined to match the specific barrel used in your JRC custom muzzleloader build. Because it is built specifically for that barrel, the die is not universal and cannot be used with another barrel or muzzleloader build.
Each JRC Custom Full Form Die is individually engraved with:
JRC Customer's Name Barrel Twist
This identifies the die with the individual JRC custom build for which it was manufactured.
