The Redding (Bottleneck) Steel Neck Sizing Die - 375 RUM is a single, conventional die for reloading rifle ammunition. This die allows you to re-size just the neck of the cartridge case, while also removing the spent primer.

This conventional die has standard threads (7/8" x 14tpi), so can be used on most reloading machines. Is primarily intended for single-stage reloading, but bottle-necked calibres work well on progressive machines too.
Case lube is essential on these steel dies. In general, we recommend using an easy-to-apply, spray-on case lubricant like Dillon's DCL, with lanolin (DLN-13733). When neck sizing only, an alternative is Imperial Dry Neck Lube (RED-07700), also available in convenient application media (RED-07900).
Case lube saves wear and tear on the cartridge cases and your reloading equipment; you'll feel the significant reduction in force required to operate the press!
This die can be used to load the following calibres: .375 Remington Ultra Magnum
This calibre is part of Redding's Series D category. Dies in Series A represent the most popular calibres Redding produces and are thus offered at the lowest prices. Dies in Series B through D are less and less popular, and correspondingly more expensive to produce.
Custom dies in most calibres are also available on request.
