hodgdons latest (as of '09) data for 40S&W and 180gr JHP
shows a min charge of 3.0grs of clays with max being 3.5grs this data has been unchanged since about 98 as I have data publish around then that is identical
now lets move on to sierra's 5th addition
same bullet (180gr JHP) same powder (Clays)
Start load is 3.6grs and max is 5.0
What gives here?
