What's the best nose shape for long range shooting?

[Distant Thunder]

I thought maybe it was close. There are a lot of bullets to try, good thing I'm retired and have a little more time for shooting and testing. Today the plan is to put a scope on my Hepburn for just that purpose, testing. I hope to remove as much of the sighting error as possible during load development and bullet testing. I still plan to go with irons for competition as long I can.
