Having shot a bunch of ballistic gel in the past I can say with a good amount of confidence that shooting ball ammo is a waist of time. It will punch a hole all the way through and keep going. So that eliminates ball. Gold Dot, Ranger Talon, Bonded hydro shock, & Golden Saber all perform about the same. So with that in mind I would suggest we shooting a little of that stuff and maybe some unknowns and hand loads. I have some extreme shocks that were donated by The Gun Vault to test and can bring Gold Dots and Rangers in various calibers. We will need a small table or some plywood and saw horses (maybe better), and a measuring tape and some old denim fabric or mattress ticking. I have the HD video camera.
