I am looking for an inexpensive way to make ballistic gelatin. I have plenty of ways to mold the gelatin. Everything I am interested in testing would require a lot of gelatin so I am looking for a way to cut costs. Knox gelatin that is used for cooking is expensive. I see why the russians use clay to test their ammo. I really want to test a Hornady SST slug. I called a friend who owns a restaurant supply. I don't think he understands what I want to do. He asked why shoot gelatin? Test the slugs by shooting a deer.
