Anybody have any idea how you would go about work up in a muzzle loader bullet to bore application? What kind of pressure signs would there be?

I want to try a new bullet which neither the manufacturer of the rifle or bullet provide Load data for.
 
The definitive answer is to straingage but that is tedious and not for everyone.

The other way is to follow the general similar bullet design and weight and not exceed similar recipes.
