max is 9.1g ( HO manual) 1050 fps was also achieved at this max charge. I am not sure what their test barrel length was, I don't have the book in front of me but I got there .1 under max. w/ a 4". 8.8g was the nicest most consistent load for me.
longshot is an excellent powder for reaching effective self defense velocities and keeping pressure safe. Nonetheless, start min and work slow watching for signs of pressure , v flattening , etc.
