Case concentricity is a huge part of potential accuracy, and Matchmaster dies deliver incredible results to shrink your groups. Matchmaster dies produce first-class concentricity by aligning the case and bullet before they ever meet, then guide them together in perfect alignment all through the seating process. The result is superbly concentric ammunition.
The loading port makes bullet seating even easier – No more fighting to balance a bullet on the case mouth. Simply drop the bullet in through the window and the Matchmaster seater die does the rest – Ready for you to run the press.
Setting up case overall length (COL) is fast and accurate with the Matchmaster’s large micrometer seater adjustment. The lettering and marks are easy to read thanks to their size and how they contrast against the beautifully blued body finish.
Whether you turn your case necks or not, Matchmaster sizing dies are ready to size to your desired neck tension and extend your brass life by not overworking your cases. Simply drop in the appropriate size bushing for your brass and start sizing. Click here to pick out your bushing.
