As the bolt was starting to get a bit firmer to open on the last few shots I probably don't need to load any hotter.
Plus the better groupings were near the lower end. So I'll play around with loads nearer to them. Might adjust seating depth a bit as the rounds were feeding OK but not real nicely. I'd like to get that better.
I'm happy that I have been able to get to the bottom of the double grouping though.
