BTW, before you succumb to the hype, try round ball in yer muzzleloader... it performs very well!
The only deer I killed with a 45 cal flintlock was almost a miss... the deer heard the frizzen strike, crouched below the path of the bullet and turned, then jumped up into the path of the bullet as it arrived. Instead of a heart shot where I aimed, the ball ran up the spinal cord and smashed into the base of the skull. Of course, all that happened without me seeing it. I had to wait for the smoke to clear, and the deer was DRT, laying 90 degrees from where I last saw it.
