Lyman's latest generation of sizing dies introduces 90-degree lube hole orientation, a deliberate design to support consistent lubrication using even modern, high-durometer lubes. Every die is constructed with a flared entrance that aids in bullet alignment, guiding them into a hardened steel chamber that ensures uniform cylindrical shaping. The internal specifications conform strictly to caliber recommendations for popular handgun and rifle rounds. Additionally, each top punch is engineered with a close-tolerance nose cavity that mirrors the shape of the bullet's front end, eliminating the possibility of nose slump or flattening during sizing.
