[QUOTE="Dean2, post: 2252405, member: 26077"] Trail Boss is a great powder for subsonic loads or lead loads in bottleneck cases but in straight walled cases like the 45-70 it is NOT a low pressure choice. You can run far lower pressures using 3031, 4895 or Varget, at the SAME velocities. My two favourite 45-70 powders for the Trapdoor guns are 3031 and Varget. (4198 is another good choice in the old guns, low pressure, good velcoity). This is straight out of the Hodgdon online load data for trapdoor rifles. Check out how slow the trailboss load is traveling but still producing 25,000 CUP at 700 fos slower. I would not load a great old gun above 1300-1400 fps, so basically starting loads of Varget or 3031 [URL unfurl="true"]https://www.hodgdonreloading.com/reloading-data-center?rdc=true&type=54[/URL] Bullet Weight 405 GR.
