Lee Precision Full Length Sizing Rem Die Features The Lee Full Length Sizing Rem Die resizes fired .223 Rem brass along its entire length restoring the case to dimensions that will reliably chamber and feed. This full length resizing process is particularly important for cases destined for semi-automatic rifles where even slightly oversized brass can cause feeding or chambering issues. Machined from durable steel the die is built to withstand repeated use across many reloading sessions without losing precision. Reloaders who want consistent trouble free cycling from their resized ammunition rely on a full length die like this one as the foundation of their process. This die requires resizing lubricant during use to prevent cases from sticking inside the die body a standard step in the full length resizing process. It is sold complete and ready to thread into any standard reloading press without additional machining. For reloaders working with brass that has an undersized flash hole Lee offers an easy x expander accessory separately to address that condition. Handloaders building .223 Rem ammunition from range brass or once fired cases will find this die a dependable affordable way to keep their reloading process consistent and their ammunition reliable.
