It's called dwell time. The slower bullet is in the barrel for more time thus is affected more from muzzle climb.
Slower bullets print higher up to a certain distance in the trajectory arch, then lower after a certain distance.
What was the temperature when testing the new lot? The extreme...

Got me all excited mentioning nitrided expander ball.

Insanely compressed powder charge blowing the case out?
