.300 Blackout Trim Die & Toolhead
The .300 Blackout Trim Die is required to trim the .223 caliber case to .300 Blackout dimensions. However the thickness of the standard Dillon Toolhead, at the location designed to use the Dillon trimmer, is too thick to accept the trimmer. Whidden Gunworks solves this problem by “notching” the toolhead which enables the trimmer to be used proficiently.
We offer the .300 Blackout Toolhead in both the Dillon 550 and 650 versions to meet your needs.
