Could they theoretically make a muzzle loader that has a tapered chamber just beyond the primer so that you can get to pressures and velocities of centerfire cartridges? I realize the danger there, being that if you did not completely fill the chamber you'd be toast but is it possible? Is there anything out there like that already.

I'm also assuming that if they throw enough metal at the rifle that eventually it would stand up to the pressure. Is that a bad assumption?

Again just curious.
