Lee Precision 90956 Collet Neck Sizing Die Only .243 Winchester

The Lee Precision 90956 Collet Neck Sizing Die is a single-die reloading tool for .243 Winchester. Sold as a die only, this is the dedicated neck-sizing piece from Lee's well-known Collet line, designed for reloaders who already have their other .243 Win dies and want to add concentric collet neck sizing to their loading bench.

Lee's Collet Neck Sizer uses a precision steel collet that squeezes the fired case neck against a hardened mandrel, producing a round, concentric neck with very little run-out. Because the die only resizes the neck area, fired cases do not have to be pushed all the way back into the chamber dimension. The collet action is self-lubricating against the case neck, so no lubrication is required, saving time at the bench and avoiding the wet cases that come with conventional resizing dies.

This die is intended for bolt-action rifles only and is not recommended for autoloaders, slide-action, or lever-action firearms, since it relies on the case neck springing back to a consistent diameter. The Collet Neck Sizing Die is machined from steel and built in the USA by Lee Precision. It ships as just the collet neck die with no other components included.
