Anyone have experience with RCBS Small Base X-Dies for .223 Rem (5.56x45mm NATO)?
RCBS recommends that cases resized with Small Base dies not be used in bolt action rifles? Can anyone explain why?
I use a Wilson case gauge and find that some cases that pass this gauge test are tight in my Rock River Arms Wilson- barreled Wylde Chamber. Puzzling. Apparently the Wilson case gause is not a sure-fire final gauge.
