Finally was able to get out and do some more tests.
Decided to try lubing inside the case neck before seating bullet on the .010 load and shoot it again before changing anything to see if it would help the ES.

That was just the kind of information I was looking for before I just went burning through powder/bullets playing with seating depth and tension. I assumed with this high of SDs that I should probably change a component, but with my other rifle my accuracy and SDs improved together so I haven't...
Bushing is .293 OD of loaded round is .294
Not developing on virgin brass. Brass was all 1x fired. I have always fired brass 1x in a rifle then started development. I am not trying to take shoulder to new case dimensions I measured new case dimensions then fired brass 1x then measured again and...
