Remembered to look in pet loads #1. None, it literally is the first in #2.
If this is a 30/30 bullet, its designed for 2100-2300/ft sec. If your wanting to duplicate a 30/30 out of a 308/06, my first thought would be searching cast loads for those. Powders which should work are 4198, and perhaps 4895. If you don't have them, good luck finding any.
Be very careful, and use someone's safely developed loads. It's counter intuitive, but reduced loads can develop extremely high pressures.
