For those velocities I'd go 60 NP, 53 TSX, or 64 PP as my top three...
Only one .224 NP made, and it is a 60 grainer by the way...
But the 60 Hornady SP, the 55 CL, or the 65 SGK will also do...
Greg-has said pretty much all I would of, I'd only add the 63 Sierra to the list. It has been one super lil bullet for me.
