Bison horn?
 

Anyone know where a guy could buy one or even a few?
I have a good friend who is into BP shooting and would love to have one to use as a powder horn.
Thanks in advance

Halfords or a bison farm would be my guess, if you wanted a raw one to work with. No idea on the cost though.

These guys could fix you up

I made mine out of a cow horn I bought in Mexico when I was about 12 years old. The brass filler and spouts are available from the couple at the guns shows I can't remember their store name off hand I'm sure someone on here would know.

Tandy leather has steer horns for making power horns. I know it's not bison, but they look pretty cool.

Cow horns polish up very nicely with fine sand paper. Epoxied a 3/ 8 flare nut fitting into the end for a spout and capped it with a 9 mm cartridge case for mine.
