I expected some variation in bullets lengths but not .008 as was the case in one of the samples. This lead me to wonder if that variance affected pressures. It does, but as SL1 pointed out, not enough about which to worry.

Yes, seating from the ogive was my thought as well. Doing so would negate any irregularities in the curved portion of the bullet. I am using LSWCs. Of course the seating die is designed for a round nose bullet. I get fairly consistent COLs if I seat carefully. Another way to seat from the ogive on this type of bullet would be to measure the distance from the bullet shoulder to the case head. This however, adds considerable time to hand loading. Although the dome shaped seat in the die handles the SWCs fairly well, ideally, a seating die specifically designed for LSWCs would be the best.
