your looking at it wrong..... the seating die seats all projectiles by the bit of the olgive/curved front half at the same fatness area for want of better term...it will be at same fatness reguardless of projectile shape even a round nose but of course that will be really close to tip...with my 170grn rn in .270 I need to back the die well out to seat projectile as cant lift seater stem high enough.
