I had a couple of old, and I mean OLD, small buffalo (bison) horns, so I thought that I would try my hand at a powder horn. It was pretty weathered, with deep fissures and I wasn't able to scrape enough to remove all of them and still have structural integrity and airtightness. It's small, but will make a decent day horn for deer/elk hunting or a priming horn for the day I get my flint longrifle built. The end cap is a piece of Claro, I just need to make a plug and fit it with a strap though it is small enough to tuck into my bag if I wish
