Maybe I missed it somewhere but were you getting velocities on these by chance?
I'm having a hard time following your group/load build up by looking at the pictures.
Going off limited knowledge 41.5 looks good and that is close to the powder charge I run.

No I was not i dont have a chrono right now, but it was my understanding the ocw was to find nodes by seeing where the group opens up and tightens then selecting your node and playing with seating depth? But I am also new to all this. What speeds are you seeing and what is your load?
Okay, so don’t take this the wrong way, but where did you learn/hear about the OCW method and how to use it? Because it is NOT about where the group opens up and tightens.
What you are looking for when using the OCW method as laid out by Dan Newberry is nodes where the centers of the groups are the same or similar in location with respect to the point of aim. This shows you the forgiving area or charge that allows for minor variations in your loading process and your shooting environmentals without affecting the impact zone of your shots.
I’m interested in if you first followed the instructions to identify pressure signs and at what charge(s) you start to see pressure.
For my money, I’d be checking out the range around 41.9-42.7, starting at about 41.8 and going to 42.8 in .2 gr increments. Then work on seating depth to tighten the groups.
Here: go to this site and do some reading, you will be glad that you did:
No harm at all man and now that you say that I do recall reading that. I read about it on ocwreloading.com thank you for the link I will deffinately read that, this is why I am here is to learn!
I believe you are referring to the three test loads starting at 10% below your max load and working the three up by 2% increments? Yes I did those they are the ones that say test group on the target. I did not run into any pressure until 43.1 I started seeing some slightly flattened primers but no cratering or anything to crazy.
Okay, good. I figured as much, but needed to know for sure.
BTW, here’s a link that has pretty much the same info, but that I find easier to read on my phone:
I’m going to go find a couple of targets to pist that are easier to use and interpret for OCW work ups.

Perfect thankyou sir and that link is the exact one that I read I will re read to cover anything I missed the first time!
