Am I crazy or is there some secret "horn tip warehouse" that nobody told me about?  Everybody seems to have horns laying around to make horn nocks but I certainly cannot find them anywhere!

I get my horn here.

I get mine from Jantz too.  Good place.

None of those at Jantz are thick enough for what I need. I'm currently working on a couple of deals though    I'll keep you guys posted...

You can use antler also,  works just as well.

Some horn for sale in our traditional bow making supplies forum by Ray Hammond.
