This is a very simple reloading block. There are several already up but I didn't see one I liked, so I created my own. This one will do 223 and 308 cases (or any other case that as a .473 inch case head). I know some of the 6mm cartridges have smaller case dimensions so if anyone wants a different version or different combo of cartridges let me know. It's easy to update the model. It print's without supports. All case holes are on the same side of the block and I've added a small hole in the back for hanging the block on a nail. I've created a version for the A1 Mini as well as the standard build plates. The standard versions holds 50 rounds at a time while the mini version does 48. Enjoy!
