External dimensions (1/2" O.D. x 3/8" long.

Fits all Redding Bushing style Neck Sizing Dies and most other custom resizing dies.

 

They are available in .001" size increments throughout the range of .185" thru .368", covering all calibers from .17 to .338 and clearly marked with size I.D. By selecting the correct bushing, you are now able to provide just the right amount of neck tension to properly hold the bullet without excessive resizing.

 

Made from heat-treated steel, the sizing diameters are hand-polished with a surface hardness of Rc 60-62, and with the addition of a Titanium Nitride surface treatment to further increase the effective surface hardness and reduce sizing friction.
