The Bushing Bump Neck Sizing Die brings you an advanced precision level by allowing you to precisely control the amount of bullet tension in your reloaded cartridges. A one-step neck sizing reduction/shoulder bump operation keeps your case necks straighter.
Bushings are available separately. If you’re making cartridges for a tight chambered rifle, you might need smaller bushings. Alternatively, you might need larger bushings if you are not outside neck turning and are using brass cases with thick neck walls. Most sizes are available in .001″ increments; just order by the inside diameter desired. We’ve included ordering charts and per-caliber selection to ease the ordering.
You can adjust the bushing to allow partial case neck sizing, allowing the unsized section to better align the cartridge in the rifle chamber.
By removing the neck bushing, you can use the Bushing Bump Neck Sizing Die to bump just the case shoulder without changing the neck diameter. This action maintains proper headspace in any chamber, custom or factory setting.
