Sinclair 30 Calibre Carbide Neck Turning Mandrel (.306") Bullet Style_Cone Point Flat Base 128 Sectional Density 0The shape and surface of all Sinclair mandrels is the result of years of experimenting by many expert handloaders. Their Carbide turning mandrels are precision ground from solid carbide stock, which yields even closer tolerances. All Carbide mandrels are ground to . 002" under bullet diameter. Adjustments on the Sinclair Premium Neck Turning tool will be more consistent with carbide mandrels due to the tighter tolerances of the mandrels.
