I get best accuracy w/ N135 in my 6BR, but AA2015 is "right in there" and the fastest - getting 3490 under a 65 V-Max/Rem 7-1/2 primer. Burns clean too! Good stuff in my 6BR, so I imagine the duce, .223 and 222 Mag would all find a home for it.
If you buy it and then want to find a home for it later, I'm sure you can get rid of it for what you have invested.
