If one is just interested in reloading for hunting and NOT caring about brass life the die manufs. instructions may be suitable. BUT, if better accuracy and case life matters forget the manufs. instructions for setting up a re-sizing die and set it up to ONLY bump the shoulders back app. .002. An exception would be if handloading for an auto rifle bump the shoulders @ .004 to insure good feeding results.What about the information included with the dies you purchase? They explain how to properly set up their respective dies. Do the die manufacturers know what they are talking about or are they just winging it as well?
