Thanks guys-

2Triggers, you really got my attention there with your comment on moving groups via crowning.
Elaborate please with what happened with your gun's performance on the 'old' loads and what happened on the target once the gun was re crowned, then what you did with your loads and how changing the load changed or moved the groups.
Did the groups just move away from each other?
If so, did they move vertically or horizontally?

I've read so much about how some double rifles end up printing one barrel's groups above or below the other, and that re-regulation would be the only way to fix that problem.
If slightly moving a barrel's crown back can move the group up or down, this could be helpful to guys out there with double rifles in need of such convergence work that'd otherwise be thousands of dollars of work and months if not years of the gun being out of hand and out of service.
