Hornady Powder Cop : HORNADY POWDER COP | Sinclair Intl

Install on your progressive press after the powder drop station to automatically check dropped charges (a smart practice, often ignored). Hornady uses a similar device in their own ammo manufacturing presses. It won’t replace careful attention, but helps monitor the reloading process. Works with all powder types and calibers.”
