Only sizes the neck to preserve the fit
No case lube needed
Cases last about 10x longer
Easy & convenient system
The Lee Collect-Style Crimp Die sizes only the neck to preserve the perfect fit of fire forming. A collect squeezes the case neck against a precision mandrel for a perfect bullet fit with minimum run-out. No case lube is needed. Cases last about 10 times longer with this innovative system. Besides being able to load the most accurate ammunition possible, the Collect-Style Crimp Die is also the easiest and most convenient to use. It offers maximum accuracy, yet is less demanding and faster to use than conventional full-length neck sizing dies. Case trimming and chamfering is kept to a minimum and the need to lubricate is eliminated. Only reload cases that have been fired in your firearm. Not recommended for autoloaders, slide, or lever-action guns.
