Frequently Asked Questions

What cartridges does this die size?

This Hornady full length sizing die handles both .38 Special and .357 Magnum cases, so you can use it for either cartridge in your reloading press.

Why use a full length sizing die instead of a neck die?

Full length sizing resizes the entire case—walls, shoulder, and neck—which is important for magnum revolver cartridges to ensure uniform dimensions, consistent pressure, and reliable feeding across batches.

What press will this die fit?

Hornady Custom Grade dies use standard .200" diameter threads and fit any single-stage, progressive, or turret press with standard American reloading press toolheads. Confirm your press accepts standard thread dies before ordering.

Is this die available as a standalone or a set?

This listing is for the full length sizing die only. Depending on your reloading setup, you may also need a powder measure die, seating die, and crimp die to complete your reload process for these cartridges.
