Improves accuracy of cast and jacketed bullet reloads
The first step expands the inside of the case neck to just under the bullet diameter for precise case neck tension in the finished reload
The second step expands the case mouth to bullet diameter or slightly over
Allows the jacketed or cast bullet to be started perfectly centered in the case mouth and properly aligned with the axis of the case neck
Can be adjusted slightly deeper for a slight flare for seating cast bullets
The Two Step Neck Expanding (M) Die won't stretch cases as does a standard expander button. Extends case life and improves accuracy of reloads. For use with .450 Marlin, .45-70 Government, .45-90, .45-100 Sharps, .45-110 Sharps, .45-120 Sharps. Standard 7/8 x 14 thread.
