The Redding Type S Full Length Sizing Die for the 303 British provides the advanced precision shooter with the means to set perfect shoulder bump while maintaining complete control of the case neck size. The die uses interchangeable bushings available in 0.001″ increments to precisely match case neck thickness to set neck tension.
In one operation, correct shoulder bump and case neck tension are set, which can be very efficient as well as being kind to brass.
Concentricity is enhanced by the ability of the bushing to float and self centre on the case neck. All Type S Dies are supplied with a standard sizing button as well as decapping pin retainer to allow the use of the die without the button.
The sizing button can be removed if you are using cases that have been neck turned or pre-sorted for neck uniformity (Redding Case Neck Gauge 26400) but should be left in when using commercial cases in a no-turn process.
The Redding Type S Full Length Bushing Die is available in many calibres. This one is for the 303 British Cartridge. Interchangeable Redding Die Bushings allow you to set the precise neck tension for particular cases.
There are several videos available showing correct set up of this die, but we like the one from Panhandle Precision here.
