The Forster Products 0.335'' Neck Bushing is a precision reloading component designed exclusively for use with Forster Precision Plus Bushing Bump Dies. If you're running a Forster bushing die setup and need a neck sizing bushing in this diameter, this is your match—built to tight tolerances and engineered to work seamlessly with Forster's die system. Unlike generic neck bushings, Forster produces theirs in .001 inch increments to match the specific caliber and neck dimensions of their die lineup, so you get exact neck sizing without guesswork.
Forster neck bushings are cryogenically treated, a process that hardens the steel and reduces friction during the sizing stroke. This means smoother operation and longer service life compared to untreated bushings. The 0.335'' diameter fits cartridges in that neck range—check your Forster die documentation to confirm this is the right size for your caliber and setup.
One important note: Forster bushings are not interchangeable with neck bushings from other manufacturers. They're built specifically for Forster dies, so if you're upgrading or replacing a bushing, make sure you're pairing it with a compatible Forster Precision Plus Bushing Bump Die. If you already run a Forster die and need a replacement or second bushing, this component gives you the consistent, precise neck sizing Forster's system is known for.
