Lee Precision .257 ROBERTS & .257 ACKLEY IMP. COLLET NECK SIZING DIE ONLY 91007

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.
