contender said:If you are reloading,,, you need manuals that have published data for the calibers you are loading. And in those manuals,,(Hornady, Speer, Nosler, Hogedon, Sierra, etc) they all have specs for the brass. If you are reloading w/o manuals,,, then you are tempting fate if you just follow other peoples "recipes" off the net,,, or other means.
