I don't know too much about loading for .223 in terms of AR-15 (actually, IDK jack s___ about loading for ARs), but if you have centerfire bolt guns and such, IMR 4895 seems to be compatible across the board.
For example, IMR 4895 will work in my M-1 rifle, all of my Mosin rifles, my Mauser, my Enfield, and I bet it would work with my K-31 just the same.
