I load a lot of 28 and 20's with Long Shot. Most are for modern guns a few are not. I have one or two loads where the velocity and pressure are both favorable for doubles. I just sent one 20 ga load off for testing that should be 7/8, 1200 fps and very reasonable pressure for a double. What I am worring about with them is velocity spread, consistent pressures and cold weather performance. I sent ten off yesterday for testing plus one to have them disassemble to verify my load. Only use in cold weather will answer if they are tempature sensitive like a some other low pressure loads were. But if I can find a 1150-1200 fps load with low pressures even for just warm weather I'll be happy.
