Rather than get into a swamp of controversy here, let me suggest...if you are going to spend hundreds of dollars on this hobby, please....go to Beartooth Bullets Calculator, do your ballistics research before you shell out the money. Beartooth uses a different power value than foot pounds kinetic energy(which is nearly useless if not misleading) for round ball. I assume you will be using round ball because you mentioned flint ignition, which confines you to round ball or Ball-ets(twist rate).
Two things you need to take away from here, info about inline muzzleloading has no bearing whatsoever to traditional round ball shooting, none. Round ball as you research it, you will find bigger is better, EVEN with somewhat reduced muzzle velocity.
