Some may not agree, but you can get estimates from using a similar bullet. Ie: Same powder and cartridge, but use a 190 SMK.
At the end of the day you still have to use your own findings over any book values. If you notice the load getting hotter than you are comfortable with, stop. This is another reason to take small steps.
I just did it last week on my AR. Didn't feel the need to test the hottest load of my development. It was over published values though. If you ever have a chance to view published values in older books you will notice they slowly come down as numbers get more and more lawyered.
