I don't bother with .223/5.56 brass. It is plentiful and is simply discarded when it splits. I aneal all other bottleneck cases every time. I have a bunch of ammo I loaded before I started anealing, so I am never 100% sure how many loadings are on this brass. I am also not afraid to use range pick up brass, I just aneal and don't worry about it.
In life, strive to take the high road....It offers a better field of fire.
