I ran across this website yesterday and saw that they had some good options that may work for you. It looks to be a bit pricey to me, but if you are in a pinch maybe it will be what you need??
Copper Creek had quite a bit in a variety of weights and bullet choices. I have used their 7mm-08, 223 and 6.5 Creedmoor with excellent results. My velocities were a little off, but I suspect that was rifle and temperature related, but the ammo was very consistent and accurate.
