The olgive is the point on the bullet were it transitions to the tip, in other words the taper as you put it. Thats where the problem is.

The other side of the olgive is where it transition from the taper to bullet body. In other words the .243 part of the bullet that gets seated into the neck of the case.

The olgive is the point on the bullet where it goes from a straight wall to the taper, it is the breaking tangent point.
