What sort of help are you looking for? I did an OCW recently on my buddy's AR in 223 rem recently and went .5gr increments across 5 loads (2.5gr total change) and didn't see a POI shift on any one of them. All were under 3/4 MOA except one and that was because of a blown primer that screwed the load.
Take those loads since they are all really good (nice shooting) and shoot them over the chrono. You might see a really accurate load but it will shoot inconsistently when chronoed. Pick one up near your max as long as you didn't have any pressure signs and get the velocity on anywhere from 5-10 rounds.
I did OCW for a different weight bullet and they were all over the place between every single load except two. Looks like you hit a node with a barrel that isn't picky at all.
