Yes, you can use ballistic gel if it has been frozen. This helps to preserve it and is mostly used in animal or human tissue. It is made from gelatin, which is highly soluble in water and is used to test firearms. Visit http://www.wisegeek.com/what-is-ballistics-gel.htm.

I don't mean to say David's answer was wrong, but I think that he missed what you were trying to ask. Yes, you can reuse frozen then defrosted ballistics gel. Just make sure there is no extra water on it.
