this projectile fills a long-neglected niche

the Flat Base Target uses J4 Precision bullet jackets for construction

Bonding the jacket to the core prevents separation from high-energy impact on tough material like bone

The original fastest bore cleaner on the planet has a new home

Sinclair 30 Calibre Carbide Neck Turning Mandrel (.306") Bullet Style_Cone Point Flat Base this projectile fills a long-neglectedThe 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.
