Generally speaking you need the slower powders to keep the port pressures high enough to cycle the action. I've tried them as slow as 870 with some success. BUT, you need a really great crimp and the taper crimp isn't going to get it, but the LeGendre side crimp will, if that too is put on heavy enough..
