The Hornady Mandrel for the Neck Turn Tool in .30 Caliber (Hornady part no. 391928) is a required accessory for handloaders running Hornady’s neck turning tool, since the mandrel is what centers and aligns a .30 Caliber case while the cutter removes brass from the neck. Even neck wall thickness improves bullet concentricity and case-to-case consistency, which matters most to precision and benchrest shooters chasing tighter groups. This mandrel is sized specifically for .30 Caliber cases, so it only aligns cases in that caliber correctly.
