Lee Precision 6MM ARC COLLET 2-DIE NECK SIZING SET 91563

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. No lube case 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.
