I had these bullets out as samples when I was revising several dimensions for a new reamer a couple days ago. They are lined up where the boat tailed section becomes the full diameter shank section. A black marker indicates where the forward section of the full diameter shank starts it's transition to the ogive. The exact full diameter shank length is noted below...the boat tail length is not included, obviously.

Top: Nosler 70 gr. BTip (.330 shank length)
Ctr: Sierra 90 gr. Game Changer (.400 shank length)
Btm: BIB 104 gr. (.450 shank length)

Clearly, the throat lengths are going be much different (longer) for the longer bullets.
