My thoughts about the Pedersoli are listed in the traditional muzzleloaders post on this subject.
Have a look at the Savage muzzleloader...it is proof tested to 60,000 psi, and in .50 cal guise loaded with suitably hard projectile (not a hand gun bullet in a sabot) backed by smokeless powder (5744, 4227, and others) would put the muzzleloader well inside the power and penetration needs for Loin hunting.
