The trigger pin, also known as a stripper, has a specific function in the ammunition reloading process. Its main function is to remove the empty case of spent or used (fulminating) primer, preparing the case to be refilled. Here are the details of the trigger pin function:

1. Spent Primer Removal: After firing a round, the primer is activated, leaving the ammo case with a spent primer. The primer pin is designed to be inserted into the empty case and apply pressure over the worn primer. This causes the primer to be pushed out of the case, leaving it empty and ready for a new primer.

2. Preparation for reloading: Once the spent primer has been successfully removed by the fuze pin, the ammo case is ready to move on to the next steps of reloading, which include inserting a new primer, charging and placing of the projectile. The fuze pin is therefore an essential part of the ammunition reloading process as it allows the case to be reused safely and effectively.

It is important to note that the firing pin must be chosen according to the caliber of ammunition you are loading, as different calibers may have different dimensions of the cases and therefore will require specific firing pins for a proper fit. Proper use of the fuze pin contributes to the safety and accuracy of the ammunition reloading process.
