Well, Compared to yesterday, I had the following results. I only fired 8 shots.

The right barrel still shot "left" of center but not as much left, and left barrel still shot "right" of center, but not as much right. And all the shots were on the same horizontal plain ..... I sighted down the rib like a shotgun, and the rifle still shot high, but not as much high.

I set up the chronograph and the average velocity was 2028 fps. My feeling is that this load of 40g IMR 4895 was just a tad too hot. The cases were a bit sticky upon ejection. I'm going to pull the bullets and try next time with only 35g of powder.

At least we made some progress.
