Brass is so cheap that it isn't worth not tossing it. Brass is all about consistancy, good expensive brass is all the same, each piece has the same capacity and all that stuff. You can sort cheap brass the same way, it just takes some more time and effort. If you shoot a flyer, it could be the bullet but it could be the brass (never you), so just toss out the flyer brass and move on. I think you will find this theory is valid, or at least believed to be valid by some. If my gun throws a flyer for no good reason, I just toss the brass, it isn't worth the effort to give another try, life is too short to use bad stuff that is worth a dime. Larry
