1. Yes, with DD tax stamp.
2. This is my major concern. The .950 JDJ round has an energy of 52,450 J and a mass of 230 g, while a .50AE is 1,666-2,200 J with mass 19-21.1 g and .600NE (the strongest handgun cartridge right now) is 11,400 J with mass 58 g. The gun
that fires the .600NE weighs 6 kg (13.2 lb). Would my design need to weigh 20-30 kg just to deal with recoil?
