Custom Rifle Reloading Die Sets

Collet Necksizing Die Set vs. Full Length Sizing Die Set

  • Lee Custom Collet Neck Sizing Dies: Use these dies for best accuracy, longest case life and no resizing lubricant. Only the neck of the case is resized the body is untouched so it retains the perfect fit to your guns chamber. Cases should have been fired in your firearm only and reloaded rounds are intended for use in just one firearm. These dies are the favorite of the benchrest crowd as there is no other die that can produce a more accurate cartridge.
  • Lee Custom Full Length Sizing Dies: Use these dies if you want to produce factory-dimensioned ammo that reliably fits and feeds in any gun. They are the first choice for semi-auto actions. Full-length sizing is a must if you are reloading for more than one firearm or reloading cases that were fired in others firearms. The addition of a Lee Factory Crimp Die is also recommended.
