Wish I had loaded more at 41.8 because when I went to 42 and 42.2 my groups open back up. So the added muzzle brake obviously changed the tune. Going to work up another load around 41.8 plus and minus and see how she goes
With that group above, I'd stay @ 41.8 grains and mess with the seating depths to see if you can get them to shrink even more (not that you need to) but you seem to have found your "accuracy node".
