The above mostly applies to autoloaders;
If you shoot a bolt action, or lever action rifle, dont full length re-size your cases;
just collet size them for the neck size of the round you are shooting; you have a perfectly sized shell for your rifle; and your cases will last ten times longer;

I am just about ready to load my first,,, I think. Something always comes up new that I need to know more about before I start. Now I am waiting to get a case re-sizer because all the brass I have collected over the years (shot only once, some twice) are different length, from 2.484 to 3.000 and the Nosler book says max is 2.494. Now mw0428 says we don't need to length size them??? We both have bolt action 30-06. Mine is a very old BSA? and hers is new Mossberg.
For myself I bought Nosler partition spitzer 180 grain and my wife Hornady 165 grain sst (which has the groove around the bullet, the Nosler one doesn't). Do these need some kind of crimp? If they do then the instruction are to re-size all brass to the same length. And if length is know big deal won't the mouth of the brass at some point stretch enough to hit a step in the barrel?
One more question is- should I keep my brass seperate form my wifes' in the future for reloading?
