The MatchMaster Funnel Powder Die Adapter is engineered to integrate seamlessly with the RCBS Powder Die Adapter (sold separately). This adapter allows you to run the funnel through either an RCBS Powder Die or a Dillon Powder Die. When paired with the MatchMaster Funnel, you get smooth, controlled powder flow into every case, reducing spillage and maintaining charge consistency, even on a progressive press like the RCBS Pro Chucker 7. This adapter extends the flexibility of the MatchMaster Funnel system, giving you more ways to set up your bench without compromising on precision. Whether you are loading precision rifle rounds or high-volume cartridges, the MatchMaster Funnel Powder Die Adapter ensures your MatchMaster Funnel performs at its best.
