Best Powders for the .223 Rem.?

[8X56MS]

I have been using H335. I only do one load now, a 64 grain Winchester PP and a Wolf Magnum small rifle primer. I am using new Hornady cases.

I get good accuracy out of my AR15, and it seems to burn clean. I am using this just for a Whitetail deer load, and for a HD load as well. I don't shoot a lot of it.
