Here are some ammunition models of various caliber.  They're good for props or demonstration purposes.

Here are the calibers that I currently have:

-.22 LR

-7.62x25mm Tokarev

-.32 ACP (.32 Auto)

-.380 ACP (.380 Auto, 9mm Short)

-.45 ACP (.45 Auto)

-.222 Remington (Tripple Deuce)

-5.56x45mm NATO

-.22-250 Remington

-.243 Winchester

-7.62x54R

-.410 Shotgun Shell

-28 Gauge Shotgun Shell

-20 Guage Shotgun Shell

-16 Gauge Shotgun Shell

-12 Guage Shotgun Shell

-10 Gauge Shotgun Shell

I know it's a rather random assortment of calibers, but I'd be happy to model anything you'd like.  It doesn't take me that long, just leave a comment.

I made them using my Anycubic Photon resin printer.  I tried the .45ACP and it was dimensionally accurate and strong enough that I was actually able to load in the magazine, chamber, and eject it.

I modeled these using Solidworks.
