Lyman's upgraded bullet sizing dies now come equipped with 90-degree lube hole spacing, a critical advancement that ensures consistent lube flow even when working with today's increasingly viscous, hard-cast bullet lubricants. These dies also feature a precisely engineered tapered entry that aligns each bullet into a hardened inner cavity designed to create true cylindrical symmetry. The internal die dimensions are calibrated to recommended tolerances for virtually all major pistol and rifle calibers. Used in tandem with Lyman's top punches-individually CNC-machined to replicate specific bullet nose contours-this system guarantees no bullet nose deformation and consistent, repeatable reloading performance.
