Hey It has always worked for me, and that's all I care about, actually it has worked for a lot of shooters, I must have prepped like that over 100 K of them over the years, you can't go to deep because the cutter bottoms out in the primer pocket, and it take literally one second to do one piece of brass, and primer pockets are not they issue whenever I chuck a piece of 223, it is more due to the fact that I am trying to get 220 swift speeds out of a 223AI, which I really don't care about expense or longevity, due to military crimped 223 brass is cheap and abundant.
