300 Win Mag Brass

[300-win-mag]

How can I tell if my 300 Win Mag brass is unsafe or 30-06? I have so much brass laying around and they were never organized on the amount of firings.

I have a 300 Winmag Wilson Adjustable Case gauge and some of my 300 Win Mag cases will not go all the way it. Seems like it gets hung up right at the belt.

i hate to be the guy that says search [ honestly] but we just recently had a discussion on this very problem. after they are sized correctly for the rifle if there are only a few i would toss em.
or put them back until i got the cure to fix them.

i dont mix brass from different rifles.
