Shamu, I made the classic error in experimentation. I changed more than one thing at a time. I lowered the powder charge by 2 grains, set the bullet out further, and fired it in a different rifle.

I've looked closely at the bullet, I think deeper seating won't do much as the cannelure is quite wide and the bullet ogive begins at the upper edge of the cannelure, so I don't think there is any further neck tension to be gained by deeper seating.
