RCBS 29501 Full-Length Die Set for .30-378 Weatherby Magnum

The RCBS 29501 Full-Length Die Set is designed for reloading .30-378 Weatherby Magnum bottleneck rifle cases. This two-die set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with Bullet Seater Plug, providing the essential tools for resizing, depriming, neck expansion, bullet seating, and crimping.
The Full-Length Sizer Die returns cases to SAAMI minimum cartridge dimensions while sizing the outside of the case, removing the spent primer, and expanding the case neck to accept a new bullet. Built-in vents help release trapped air and excess lubricant, helping reduce the risk of case damage during operation. The die also maintains headspace within minimum tolerances to help prevent unwanted changes to case body length during full-length sizing.
The included Seater Die features an integrated roll crimper that secures the bullet as it is seated. This design streamlines the reloading process by combining bullet seating and crimping in one operation when appropriate for the load. Manufactured by RCBS, the 29501 die set offers a practical setup for reloaders who need consistent case preparation and dependable bullet seating for .30-378 Weatherby Magnum ammunition. Use with compatible reloading equipment and follow established reloading data and safety procedures.
