You are correct.
The standard SP has a .6 inch radius ogive. I also make a .5 inch radius, the .8 which is a really nice and graceful form without getting nose heavy for bullets from 6.5 MM up, and the 1 inch radius. With the longest radius, bullet weights must be fairly high for good accuracy, this to have enough bearing to support the long nose. In 30 caliber I don't make it in weights lighter than 180 gr and it performs best with 190 grains and heavier.
