I did pressure tests of the RST roll crimped 1 1/16 ounce classic field load. It pressure tested at 6600 psi and velocity in the mid 1100s. It is the prettiest 12 gauge shell I have ever seen. I also pressure tested the Falcon Ultralite 3/4 ounce loads and they tested at 4300 psi. I have considered making a test barrel from PVC to test these RST Falcons. Most guys I have asked have been skeptical about the PVC withstanding the Falcons. I think I could get away with it. The RST Falcon and Falcon Ultralites probably pressure test way below what a black powder load would test. By the way, the Falcon Ultralites sounded just fine when shot in cold weather. I did not "freeze" them, but I did leave them outdoors at about 20 degrees overnight. I am going to freeze a box when the weather gets cold again. They are the best shells I have ever used in Damascus guns. rstshells.com
