articap, I know what you are saying.
But, you are thinking like one who equates everything with modern guns.
A traditional muzzle loader is not a 30-06 and trying to pretend differently is an exercise in frustration.
As one who has shot muzzle loaders, almost as a life passion, for over 40 years, I understand the difference.
They are different critters. A muzzle loader using a patched, pure soft lead, round ball is an excellent killer. All the fantasies about 'penetration' , knock-down-power, sectional density do not kill any better than a well placed prb.
