I was having a discussion with someone yesterday as to what the most powerful black-powder weapon could possibly be. Its a hard thing to judge, with so many varying loads and calibers... but does anyone know? My bet was on the Kodiak Express, but I could certainly be mistaken. In my opinion, a Bess loaded with 120 grains and a PRB has done significant damage to targets of metal and wood. I'd like to hear peoples opinions, and I do realise this is a very broad question, so I apologize.
