Anything one should be aware of? Have some older brass, noticed some of it is labeled +P. Also noticed several of my reloading manuals have +P sections. I would assume that +P data has to be used in +P cases? Some of this brass is old enough I didn't know the label.. Super Speed, had to look that up. Winchester before Super X.. I did notice that the +P brass is about 14g heavier than the NON +P brass. Again I assume the cases are thicker? Both were Winchester Super X cases.
