 What I have been wondering about with the ballistics gel though it says its only stable up to 95F so I would have to find a way to keep it cool during testing. I am more interested in how different shot sizes react to striking bone which doing some rough math plywood is around 50% the density of bone so im now wondering if say a 1" plywood sheet would be similar if a projectile hit 1/2" of bone just as a example.
