You probably already know there is a slight difference between the 6.5x284 Win and the 6.5x284 Norma so depends on which type of brass you will be using on which reamer you choose. Same for the reloading dies.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
