WARNING: These designs are not suitable for real-world use as a 3D printed item without modification. A safer option would be using these printed models to create a mold and then casting the design with a more durable material. This design was created around one of the yellow plastic shells commonly used in reloading. The tapered powder pocket is specifically designed to hold 40 grains of black powder. To ensure proper function, this bushing must be securely attached to the shell casing using epoxy or another semi-permanent adhesive. These designs are currently untested and should not be used without careful consideration. I assume no responsibility for any harm caused by the use or misuse of these files. Repeated exposure to stress can weaken 3D printed materials, making them potentially hazardous when used in critical applications like reloading. To minimize risk, it's recommended to create molds from these prints and then cast the design with a more suitable material. Always exercise caution when working with reloading equipment and follow proper safety protocols. If you find this file useful, consider showing your appreciation by tipping me so I can devote more time to designing innovative models like this one!
