Shell Holder (or case support, in Portuguese) is an essential part of the ammunition reloading process. It performs several important functions during the ammunition reloading process, most notably in reloading single-action firearm ammunition such as handguns and some shotguns.

Here are the shell holder's main functions in ammo reloading:

1. Hold the empty case: The shell holder is designed to hold the empty ammunition case firmly and securely during the reloading process. This allows you to work with the case precisely and consistently.

2. Positioning the Case: The shell holder is designed to position the case in the correct station on your reloading press where reloading operations such as projectile insertion, powder insertion and crimping can take place properly and accurately.

3. Aligning the case: The shell holder helps to align the case correctly, ensuring that reloading operations are performed evenly and avoiding problems such as misaligned bullets or excess powder.

4. Ease of extraction: Once the ammo is reloaded, the shell holder makes it easy to remove the case from the reloading press in an easy and controlled manner, allowing you to move on to the next case to be reloaded.

In summary, the shell holder is an essential piece of ammunition reloading as it plays a key role in the safe and accurate handling of empty shells during the reloading process. Be sure to choose the correct shell holder for the caliber of ammunition you are loading, as different calibers require specific shell holders to ensure a proper and secure fit.
