That's more like it. It still seems that those groups are wondering around a bit, could it be changing velocity over a long shot string? Sometimes those stock BSA regulators have a curve in their shot string.

Sometimes those stock BSA regulators have a curve in their shot string.The wandering groups is my fault. I was adjusting the windage a bit trying to get perfectly centered. I didn't actually even shoot these groups consecutively. I would shoot a couple of groups, adjust windage, pop a couple of spinners, shoot another group, etc. I'm going to run a whole shot string over the chrony hopefully today and also try to see what a couple of 100 yard groups will look like.
