Most reloading manuals give jacketed bullet specs. Do not be afraid os the cast loads they are spectacular. Always use the springfield loads until confirmed by manufacturer that higher pressure loads are safe. I shot a bull moose a few years back with 500 grain hard cast, water squelched over 70 gr Geox FF that went in left rear hip( I know there are no hips on the front) and exited rt front shoulder taking out both joints and about six inches of spine. never found the bullet to see how it did. I kinda guess I know.
I have a Lyman cast reloading manual that has a lot of really good info if you decide to go old school.
