We are having a shoot this coming weekend and have some tannerite to use. What I need is some good ideas on things to attach them to to make it a litter funner. We have used 5lb flour bags in the past that worked reall well, but I am looking for some more ideas. We will be using some full autos, so steel reactive targets get banged up too much, so we dont use them. We cant use anthing that might catch on fire.
