My .54 Hawken is a Pedersoli Rocky Mountain version. It is an absolutely a beautiful piece of work with a gorgeous maple stock. When Cabellas put this on sale from $999 down to $699, I had to jump on it!
Barrel is 34" long with a 1 in 66" twist. This should be well suited for accuracy with patched round balls, but not a fast enough twist rate for conicals or sabots.
I am still in the learning process with the muzzleloader. I have been working 7days/week for the past month, so I have only been able to take it to the range twice so far. I'll get to shoot it again next week-end.
