Help me with my OCW, again

[bfk4lyfe]

Can someone help me read my OCW test here.

Load info: Proof 24" 260 barrel. 200 rounds through it, cleaned just prior to today. 1x fired Starline, bumped .0015ish, BR2's, H4350 and Berger 130 Hybrid ARs. Currently at ~2.880 OAL which is about .030 off the lands. I only started with that OAL out of laziness as I couldn't remember how long the AI AW mag is and it was upstairs, and I was downstairs...

I don't think I'm too bad of a shooter, but with the exception of 43.4 they all more or less look the same to me.

If it were me I'd choose the 43.4 or 43.7. I feel those two are in-between the nodes. You could make more rounds for those grains and in-between, 43.4, .5, .6, .7 and see which from there. I say those two specifically because looking at the nodes it looks like you could go up or down in grains and still be at a good place taking into account the atmospherics.
