the first and only powder horn i bought was that india one from tow. i hated it's color and the way it was carved. it looked like something that didn't belong in the usa. but those are my personal feelings. i like black tipped cow horns that mottle down to near white. i like simplicity. again, a personal thing, and to each their own.
i made my first powder horn last week. it's not period correct, but it works quite well. for me, this has been a learning curve on multiple levels. now i know exactly how best for me to make powder horns for ... me.
make as much of yer own gear as possible. no, not to save money, sometimes it will cost lots more. but you will have the satisfaction of rolling yer own, and if done well it will be a grandson hand-me-down.
