I like your line of reasoning, but Chris Long thinks increasing bullet weight (in the bullet weight box - not the bullet selection box) accounts for increased barrel friction.
In other words, for your Norma 130 bullet he might enter 131 in the bullet weight box and for your Sierra 140 he might enter 142.2 in the box.
When I'm calibrating QL to my bullet/powder/primer combination, I try to get it to follow the two velocities of the two test charges by adjusting first powder ba, then weighting factor, then bullet weight. But if it won't track with those three adjustments, then I go to start pressure.
Hope this helps.
