A 50 round loading block for 9mm pistol rounds. Other cases with roughly the same diameter rim fit as well. Ex .223/5.56x45, .300blk, .350 legend, .22 TCM, 7.62x25 Mauser/Tokarev. It will also hold .38 special and .357 with the rim up.
I made this for loading 9mm, but I have also uploaded a blank sided version of the tray if you intend to use it for other calibers. I have made a few remixes for different calibers.
