About 50 miles from my home there is a shot tower that was used during the Civil War. The tower and the land around it are now a park. Perhaps the rangers would let one use it if they asked nicely? :-) And it might be wise to take your own virgins rather then trying to find any at the local pub.

But for the ones who would prefer an easier way to do it, here is an article for making lead and bismuth shot at home. I would think you could put in as much antimony as you would want. http://www.svartkrutt.net/articles/vis.php?id=8
And here you can purchase the shot maker http://littletonshotmaker.com/
