Our customer is buying brass cartridge cases from commercial firing ranges and selling them to re-loaders around the country. Two popular pistol cartridges are the 9mm Luger and the .380 Auto caliber, which are very similar. The diameters differ by only a few thousandths of an inch.

B. Dash designed and built a machine to separate them. The cases are dropped from a Dillon collator onto two rods, slightly closer together at the upper end.

The rotation of the rods causes the cases to work down the slope. A short way down, the .380 cases fall through and are diverted into a bucket. The 9mm cases, 0.010” larger, go farther down before they fall through and are channeled into their bucket.
