Its the exact same thing with a different datum point.

Ironically he's just swapped one "moving target" for another. Because what is 'jam'? One case with its own neck tension and runout will never leave the bullet in the exact location as any other case on earth.
Might as well use the 'just touch' method and take an average if you're looking to be super precise.
