Reloading Process for Cartridges
If you're interested in reloading your used cartridges, a series of meticulous steps must be followed to ensure the utmost accuracy and reliability. Here is a detailed guide to the process:
Cleaning
The first step is to thoroughly clean the used brass cartridge cases. This can be achieved through an ultrasonic cleaner or a case tumbler with cleaning media. The purpose is to remove any powder remnants and dirt, ensuring the brass is ready for the next steps.
De-Priming and Re-Sizing
Next, de-prime the cartridge case. This involves removing the primer while ensuring the case is not damaged. Followed by re-sizing the cartridge case to its original dimensions. This step is crucial for consistency and accuracy.
Trimming the Case
Trim the case to the correct length using a case trimmer. This ensures that the case is the proper length, which is essential for optimal performance.
Swaging Military Brass
Some brass, particularly military brass, may require a primer pocket swage. This step prepares the brass for reloading by shaping it correctly. Ensure that brass of different manufacturers or arsenals is not mixed to maintain consistency.
Sorting and Picking
Sort the brass by manufacturer, arsenal, or year. This step involves careful selection to ensure compatibility. It is important not to mix different manufacturers or civilian/military brass to maintain the reliability of the ammunition.
Priming the Cartridge Case
Once the brass is prepared, prime the cartridge cases. This step involves inserting primers into the cartridge cases. Ensure that the primers are correctly seated and functional.
Loading Powder
Select the appropriate powder type as directed by the manufacturer's reloading guide. Start with the recommended minimum weight and ensure that the correct amount is added to each cartridge. Double-check to verify that the correct amount of powder is present.
Seating the Bullet
Seat the bullet to the specified depth. This can be done using a bullet seating die. Ensure that the bullet is properly seated to maintain consistency and accuracy.
Crimping and Lubricating (if needed)
If desired, the case mouth can be crimped into a cannalure, and bullets may need to be lubricated if they are not already coated. For lead bullets, add a gas check to the base for rifle loading. This step is crucial for optimal performance.
Alternative Methods of Manufacturing Bullets
Bullets can be manufactured through various methods, including casting, swaging, and turning:
Casting: This is the simplest and oldest method, involving placing lead in a molten pot and pouring it into a mold. A lubricating tool called a lubri-sizer then adjusts the size and adds lubricant to the bullet.
Swaging: Using a reloading press, a bullet swaging die is inserted into the press with a bullet jacket and lead wire for the core. The press then swages the material into the final form.
Turning: This method is used for solid bullets, such as those made of copper. A lathe is used to shape the solid into the desired form.
