One thing to take note of and I hesitate to post it in the presence of reloading gods who appear to call differing opinions 'crap'.

The volume occupied by the bullet in the case is an important and often overlooked reference, as long as the case volume (by a seated bullet) is unaltered it does not matter what the nose form / profile is for the same weight bullet.
Obviously you cannot compare flat base and boat-tail so easily - takes a little math to calculate the volume - but like for like is a doddle.

This seating depth (amount of bullet in the case) is an important datum to recognise and record.
