Bullet mold "1 Ogive radius" vs "2 Ogive radius"

[Lead Waster]

OK, when I look at the Lee bullet molds I see 1 Ogive Radius and 2 Ogive Radius to describe the bullet. I looked up "ogive" and it means "pointed arch" basically the shape of a bullet before the cylindrical part. Then there are all sorts of tech talk. What's the dumbed down explanation of a 1 ogive radius bullet verses a 2 ogive radius bullet? Is one "sharper" than the other?

Thanks!

1R ogjives are circular, like a round ball.

2R ogjives look more eliptical, like a 9mm FMJ

The higher the number of the ogjive, the more pointed the nose.

Awesome, thanks for the answer! I thought it had something to do with the width of non-rounded part.
