I have about 5000 180 LTC to use up, my preferred powder is AA#7, but can't find any. I managed to snag a 4# jug of WST, but data is sketchy. Winchester lists a max load of 4.3 gr with a 180 tmj, velocity of 888FPS. My Lyman book lists a start load of 4.7 with a 175cast bullet. Max load of 6.0 gr! This gets me to doubting what I'm reading. Anyone have any experience with this powder? I'm looking to get velocities in the 975 range.
