What's the ballistics box problem? Do you have pis of it?
Hyper absorbent polymer crystals. It basically gels the water so it will suspend a fired bullet and doesn't splash out of the box like water. The downside is the outward hydrostatic pressure is very rough on the containment vessel (my catch box). I'll probably end up declaring failure and just run straight sim test media if I can't get the box welded.TominCA said:What is the catch media?
