RE: If you could only own one bp rifle....
FG - if you can't shoot those flinters, you can send them to me. I have lots of BP to shoot off.
Now if I had to have only one BP rifle I would go to a gun shop and find a nice T/C Renegade or Hawken flinter (used) and then order me a 50 cal Green Mountain Long Range Hunter barrel.
Hmmm.. come to think of it I have 3 of them just like that.
