    Lee Collet Dies

    If you’re a long-time user of Lee Collet Neck Sizing Die you may notice we have modified the Collet so a small portion of the neck protrudes through the end of the Collet-Sizing portion. This often-requested modification was implemented in 2019. 


    This change allows the portion of the neck that protrudes above the Collet to remain in its fire formed condition. This provides a natural flare to the case neck allowing easy and concentric seating of bullets. This is especially important when seating cast bullets or low drag coated bullets.

    Noted author and cartridge designer M. L. (Mic) McPherson has suggested this modification for years for its ease of use, better function, increased case neck life (without annealing), and improved accuracy.


    Lee Collet DiesThere is no loading system that will load more accurate ammunition than Lee Collet Dies. No one but Lee has ever dared make a guarantee like this-- Smallest group size or your money back. A collet squeezes the case neck against a precision mandrel for a perfect fit with minimum run-out. No case lube is needed. Cases last ten times longer, so the savings on only 35 cases will pay for the dies. Maximum accuracy is usually achieved by seating the bullet out far enough to touch or almost touch the rifling. This provides the shot start pressure normally supplied by the crimp. That's why a dead length bullet seater is included to complete the most accurate reloading system ever made. These dies size only the neck to preserve the perfect fit of fire forming. Only reload cases that have been fired in your gun. Not recommended for autoloaders, slide or lever action guns.
