Time to continue load development with my .44-77.

I always preferred the 1 caliber elliptical radius to no more then a 1 1/4 for my black powder bullets. A 1/2 caliber is a round or ball nose.
Elliptical ogives have a constantly changing radius about two focal points, so you can't specify them with a single ogive radius figure. The best way to describe them quickly and positively is by the axial length, or distance in calibers they extend above the shank along the center line of the bullet.
However, this method means you have to be aware that the changes in length are huge when you go from a 1 to a 2 caliber.
The proper elliptical length is very important for a stable balance with the low velocity's ROT we shoot.
