Morning John.

I have fired all manner of Black powder weapons some with live ammunition, with 1.5 charges in some instances where the touch hole had been drilled a little too high up the tube, and non from India pattern Bess, through Long Land pattern, Baker rifle nor Charleville had a noticeable hard kick nearly as much as a 12 bore shotgun.
The only surprise I got was with my Medieval hand gonne, which not only kicked but although only using a charge half that of my 12 gauge musket sounded like a cannon. This was due to it having a chambered bore at the stock end of the barrel.
The only gun I have fired that was a real pig is the Martini Henry. Kicked like a mule despite being warned about it and seating it well into my shoulder. I would not like to spend any length of time using that baby.

If you want to talk accuracy barrel weight etc I will give you my experience of that too.
You may be surprised about one or two aspects of that. I know that I was.


Rob.
