FORSTER NECK BUSHING .310

THIS ITEM IS ONE BUSHING ONLY, DIE NOT INCLUDED. If you're making cartidges 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. Forster offers flexibility, bushing sizes are available in .001" increments. Order by inside diameter desired.
