Google is your friend with this dilemma.
I have used Sierra 55 GK SP with great results from the 223 and bet the 60 Partition would be good as long as the twist is there to shoot them.
Others will chime in about the Hornady 55, Sierra 63 and Barnes TTSX, all of which I am sure will turn the lights out on a buck pretty fast but I have no hans on experience with those bullets.
