Lee 357 Sig Micrometer3-Die Set includes Steel Full Length Sizing Die, Powder Through Expanding Die, Micrometer Bullet Seating Die, Universal Shell Holder, powder measure and instructions with load data.


Lee resizing lubricant is required with this die set.


Flat nose bullet seat adjust screw for wadcutter and semi wadcutter bullet users. Order MB5872.


If a crimp is desired, the bullet seating die can be adjusted to apply a taper crimp. If you don’t mind the extra step, the FACTORY CRIMP DIE will allow you to separate seating and crimping. This maintains the dead length seating and simplifies the die setting.

Factory Crimp Die

Lee 357 Sig Short Bottle Neck Collet Style Factory Crimp Die incorporates a collet to apply a factory type crimp. Makes these very difficult to crimp cartridges a delight to reload. Bullets do not need a crimp groove, as the collet is so powerful, it will form one to crimp the bullet firmly in place.
