The Lee Collet Necksizer Rifle Die for 6mm ARC (brand part no. 92209) uses a steel collet to squeeze a fired case around a precision mandrel, creating a precisely aligned case neck while reducing runout. The result is better accuracy and extended case life, since this die sizes only the neck and requires no case lubrication at all. Lee recommends this die specifically for cases that have already been fired through your own firearm, which lets the collet work with brass that’s already fire-formed to your chamber. For 6mm ARC shooters chasing tighter groups from the same rifle, this is a simple, low-mess way to size brass between loadings.
