LEE PRECISION 375 H&H MAG COLLET 2-DIE NECK SIZER SET

Notify on availability

Description:

Experience unmatched accuracy with the LEE COLLET 2-DIE NECK SIZER SETS.

The LEE PRECISION 375 H&H MAG COLLET 2-DIE NECK SIZER SET is designed for reloaders who demand the highest precision in their ammunition. With its innovative design, this collet die system ensures that your cases are resized to perfection.

Why Choose Lee Collet Dies?

There is no loading system that will load more accurate ammunition than Lee Collet Dies. A collet squeezes the case neck against a precision mandrel for a perfect fit with minimum run-out. Here are some key benefits:

  • No lube case is needed, simplifying the reloading process.
  • Cases last ten times longer, providing significant savings.
  • Maximum accuracy is achieved by seating the bullet to touch or nearly touch the rifling.

Complete Your Reloading System

This set includes a dead length bullet seater, which is essential for achieving the most accurate reloading system ever made. Remember to only reload cases that have been fired in your gun, as this preserves the perfect fit of fire forming.

Important Considerations

These dies are specifically designed to size only the neck, making them ideal for precision reloading. However, they are not recommended for autoloaders, slide, or lever action guns.

Upgrade your reloading setup with the LEE COLLET 2-DIE NECK SIZER SETS and experience the difference in your shooting accuracy!



Top takeaways

  1. Lee Collet Dies provide highly accurate ammunition by squeezing the case neck against a precision mandrel, eliminating the need for lube and extending case life.
  2. The set includes a dead length bullet seater for maximum accuracy by allowing bullets to be seated to touch or nearly touch the rifling.
  3. These dies are designed to size only the neck, preserving the perfect fire-formed fit, and are best suited for cases fired from your specific gun, not recommended for autoloaders or pump/lever actions.
