Case sizing involves using the Co-Ax® Press to form a properly lubricated cartridge case through the interior of a resizing die. The sizing die’s interior is slightly larger than a new cartridge case. This resizing process returns the fired brass case to a size that will always allow it to fit back into a minimum-sized SAAMI chamber.

SAFETY – Please follow all pertinent safety procedures such as wearing safety glasses; being in a well-lit and well-ventilated workspace without flames, sparks or static electricity; and having all reloading tools in top working condition.
As you become more proficient in reloading, you will fine-tune your own process based on your tools/equipment, the type of shooting you do, the guns you reload for and the goals you have for your handloaded ammunition. We suggest that you continue to read, learn and understand various methods so that you can find the system that works best for your needs.
TIP – To keep the inside of your dies scratch-free, ensure that the outside and inside of your cases are free of powder residue and other debris, case necks are deburred, and the die itself is kept clean. Chips that result from trimming and deburring, or a case that has not been deburred, are especially damaging to die interiors. These chips can become embedded in the die interior. The resulting brass against brass effect “galls,” or wears away, minute pieces of brass on the case and gets worse with each use of the die.
