Lyman 5.7x28mm FN 3 Die Set - LYM 7460486

This three-die reloading set is designed for 5.7x28mm FN ammunition and features an improved expander button that reduces case stretching compared to standard dies, extending case life. The progressive die design includes a case neck expansion step that sizes to just under bullet diameter for precise neck tension, followed by a second expansion to bullet diameter for proper bullet seating. Ideal for reloaders using cast or flat-base bullets who require consistent, accurate reloads.
