Forster Products neck bushings are designed to size case necks to exact requirements in a Bushing Bump Neck Sizing Die. An ultra smooth bushing produces better loaded rounds, with Forster using a super-cooling cryogenic process where cryogenically treated steel produces filler particles that refine and close the steel’s surface. The BUSH-240 delivers a superior interior finish for “smooth as silk” neck sizing, ensuring minimal wear on your brass and consistent results across your reloading sessions.
Interchangeable bushings are available in 0.001 in. increments to enable custom neck sizing and fine adjustments for case neck wall thickness. The bushing relies less on the chamber of the rifle and more on the wall thickness of brass being used—it is this wall thickness that determines how far down the bushing needs to size in order to have proper neck tension. This precision control is essential for match-grade reloading and allows shooters to achieve the exact neck tension required for their specific ammunition.
A one-step neck sizing reduction/shoulder bump operation keeps your case necks straighter, improving accuracy and prolonging case life because the body of your case maintains its fire-formed “glove” fit to your rifle’s chamber while bumping the shoulder of the case to maintain excellent case neck concentricity—best of all, it prevents overworking the neck and allows you to control the amount of neck tension for your bullet seating operation.
