I'd go with 42.9. The charge above and below looks to be in the same spot, so should give you good results and room for error.

Thats kinda what I was thinking too. I'll run another ocw test with loads between 42.5 - 43.5 and see what happens.
I really like that the lower charge weights group well. No need to stress out the system and equipment if you dont have to. I get descent velocity to stretch
out to a 1000yds if need be.

42.9 looks really good! Looks like if you stay around there, you will have a nice little shooter.

you have a scatter node at 43.6, which points back to 43.0 as the OCW. Scatter nodes are 1.5 percent away from the OCW's... so I'd go with 43 even. Good shooting rifle.

42.9 is where I'd stick. Good charge insensitivity and appears to be your barrel node as things calm down in that area. You can run a finer test if you wish or you can start playing with seating depth but honestly you're looking at enough accuracy as is. Load a bunch and shoot the shit out of em. Doubtful but the last question I'd ask was if you saw any signs of pressure in your process.

I got very slight cratering at 44.7. I mean very slight, you have to look good to see it. All the other charge weights were fine.
