The Lee Precision Collet Die .300 Winchester Short Magnum preserves the perfect fit of your fire-formed cases by sizing just the neck of your cases, thus ensuring greater consistency, accuracy and increased case life. Neck-sized cases can last up to ten times longer than full length sized cases.

These results are achieved by using a collet to squeeze the case neck against a precision formed mandrel which creates a precisely aligned case neck with greatly reduced run-out. Neck sizing should only be used with cases that will be fired in the same gun. Neck sizing is not recommended for autoloaders, slide or lever action guns. If you need to load cartridges that will be fired in multiple, different guns, in autoloaders or slide or lever action guns, you should choose a full-length sizing die.
