What's the difference in a "full length die", and a "small base set" die? Also, will die work on 5.56 brass that might find its way into a batch of .223 brass?
Asked by: LR60guy
A Small Base sizing die is a little tighter in the web area than a Full Length Sizer. Semi Auto, pump and lever action rifles tend to have tighter chambers than bolt action rifles, thus requiring the tighter small base sizer. The RCBS AR Series .223 Rem./5.56mm x 45 Die Set is designed for .223 Rem/5.57mm ammunition and is not recommended to be used with other calibers.
