This precision sizing die with plunger and lock nut will fit a standard reloading press with 7/8 x 14 threads. The plunger fits in your loading press in place of the shell holder. The colored end of the die is the entry end for the bullet.
If you don't own a loading press you can simply screw the lock nut onto the sizing die and clamp it in a bench vice.
Please note, these dies are gently tapered to allow for easier bullet installation. All dies have been inspected with a plug gauge to assure proper size. The die and plunger are wrapped in Anti-Corrosion paper and are sealed in plastic bags to help prevent rust. After use, clean the die and plunger and repack them with the paper to prevent future rusting.
