That's a nice rifle

My 223 has a one in twelve twist, but I wish it was 1-9.
Just be careful with the lighter, softer bullets (52gr speer and such), I haven't heard it much, but a few guys have said that accuracy is nasty because the bullet is disinigrating in the barrel.
Varget is an excellent powder for the 223, so is 748. I've used both in previous 223's with very good results. I'm currently using H322, but once that is used up, I'll shift over to TAC. There is really no copper fouling to speak of with TAC.
Cases, all work, though with Winchester factory cases, I've been having them split after 2-3 shots. I've never seen any accuracy advantage between on case or the other, though the lapua cases required absolutely no case prep.
Primers, I like CCI for my rifles. Good hard cup, and good ignition, and available generally.
Bullets, there is an embarrassing number of choices to choose from; just remember that a good target bullet is often not a good varmint bullet, and neither of those are good for the larger game.
I don't feel that it's appropriate to give load data over the net, as I could type or look at something wrong, and that could have nasty results. fair to say though that you've picked one of the most versatile and pleasant to load for cartridges in existence.
