First OCW, First time reloading. Pics from range up, help with picking OCW.

I recently started reloading and loaded my first rounds for OCW testing. My loads are as follows...

308
Lapua Brass
Fed 210 primers
imr4064
175 smk

All rounds were loaded to 2.800, I loaded these rounds from the tip of the bullet to the base of the cartridge. At the time of loading I didn't have a bullet comparator to measure, ogive, I do now. When I measured ogive on these bullets it had quite a bit of variance due to me adjusting my die to get close to 2.800. Next time my reloads will be more uniform as my measurements will be better.

Any advice on the pics below would be appreciated. I'm thinking I have a node somewhere around 42.8-43.1 and 43.4-43.7
All groups were 3 round groups.

I'd go with 43.7
Kinda hard to read sideways . You might want to run it again starting at 43.1

Sorry about the pics being sideways. I may run another bunch and do .2 grain bumps from 43.1-43.9

I was going to say 44, myself. There is a pretty sharp change in POI consistency between 43.4 to 43.7. Maybe bracket around 44?

I need to run a batch from 44. To 45.6(max charge weight). I stopped short due to reading a lot about pressures when getting into that range. I was still showing no pressure signs.

43.7 and 44 look good. Run another batch with 43.5, 43.7, and 43.9 and see how it turns out.

I need to add you need to check your position, rest, etc. as your outliers appear to be horizontal which may be you.
