    I have a whole bunch of .223 range brass. I need to seperate it out for reloading. How do I spot the difference?

    If it's once fired brass the easiest way to tell is if it has a military headstamp, it's crimped.

    If you're not familiar with different headstamps there will be a distinct ring around the primer pocked where the brass has been swaged inward. Simply ream the primer pocket with a couple of turns... you'll feel the brass being reamed out.

    If you place your pocket reamer in the pocket and it spins freely the pocket has already been reamed. It's a one time operation... once a pocket has been reamed it doesn't need to be done again.

    To add to Jacks suggestion of reaming, I would suggest swaging the primer pocket. I find it is more precise, faster, and easier because if you don't ream it enough the first time, you need to do it again, which generally isn't an issue with swaging once it is properly adjusted. I use the RCBS press mounted swager, which costs around $30. Dillon makes a bench mountable swager, which costs around $100.

    The crimped primer pocket will look like this,
