Brand: RCBS 87590
The RCBS powder checker die uses a plunger to provide a heads-up visual confirmation of a proper charge. Once set for your load, the indicators should align for a proper charge, and will show obvious variation for an undercharge, or double charge. Black oxide coating provides a high contrast backdrop to white indicators, and will work with most calibers .22 and up. Powder check die is typically installed immediately after powder charging station.
