This is a good discussion. One which will assuredly not sway anyone from using what works best in their current rifle and hunting situations. No specific bullet or load will satisfy everyone. We all make choices about what is best for "us".
I respect Grouse for the choices he has made. And I'm sure Grouse respects mine. We've both been at this game for a few years.
Find what works best in the rifle you choose,,and have fun shooting it. That's what muzzleloading is all about.
