Frequently Asked Questions

What is the first step to setting up a full-length sizing die on a reloading press?

The first step is to ensure the shell holder is correctly in place on the reloading press. Once the shell holder is seated, you can proceed with adjusting the die itself for proper sizing.

How do you determine the correct depth for a full-length sizing die?

You determine the correct depth by raising the press ram to its highest point and then screwing the sizing die down until it makes contact with the shell holder. This ensures the die is set to its maximum travel.

Why is it important to tighten the lock ring on a sizing die?

Tightening the lock ring secures the sizing die at the correct depth. This ensures that every time you screw the die into the press, it will bottom out at the same spot, providing consistent and repeatable case sizing.

What is the recommended protrusion for a decapping rod?

The decapping rod should stick out approximately 3/16 of an inch. This ensures that it effectively presses the primer clear of the case, allowing it to drop out cleanly when the case is sized.
