9mm Dummy Bullet

thingiverse

Got tons of 9mm casings but don't want to shell out for Snap Caps? Combine the durability of brass casings and the inexpensive process of printing to make some dummy rounds for yourself for functions checking, training, and display! Print, resize, and glue, it's as easy as that! The lower sides are relieved to allow for extra glue and to provide insurance against the ATF classifying it as an ammunition component. These inserts occupy the entire interior volume of the casing so they're the perfect length every time! They will give a COAL of about 28.5mm +/- 1mm, so they should work in all actions and magazines. If you find them too long or too short, just scale the Z direction in your favorite Slic3r program and print away! I printed 10 of them with 2.6m of ABS filament, so they're stupid cheap. BATFE Disclaimer: These inserts render a 9mm casing completely inert and unable to be fired even if loaded with a powder charge or primer. They are for display only. You may also get in trouble for selling these completed prints without a Class VII Federal Firearms License in the US. Check your local laws before attempting.
