The Redding Deluxe (Bottleneck) Steel 3-Die Set - 257 Rob I40 is a set of conventional dies for reloading rifle ammunition. Redding's Deluxe set includes three dies: 1) a full length sizing die, 2) a neck sizing die and 3) a standard seating die.
This die set allows you to re-size only the neck of the cartridge case, or the full length. In both cases you will also remove the spent primer.
The standard seating die can also apply a crimp, if required.

These conventional dies have standard threads (7/8" x 14tpi), so can be used on most reloading machines. They are 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 set can be used to load the following calibres: 257 Roberts Improved 40°
This calibre is part of Redding's Series C 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.
