FORSTER Bushing Bump Neck Sizing .333

Bushings allow you to size the neck of the cases according to your exact needs in a Bushing Bump Neck Sizing Die.

An ultra-smooth bushing produces higher performing cartridges, so Forster uses a cryogenic super-cooling process. Cryogenically treated steel produces filler particles that refine and close the steel surface.

The bushings are heat treated and honed to achieve the precise declared internal diameter.
