Hi Guys,
I scored some WW Autocomp powder locally, it seems to fall between AA5 and AA7, and very near my current .41 Mag powder SR-4756(only have a few pounds left so I need to locate alternative powders)
I normally push my lead 220g Keith SWC around 1100 fps...I use AA#9 for my "real" .41 loads.
Hodgdon shows a 220 JSP at 1154fps with 8.3grains of Autocomp....
has anyone run any AutoComp across the chrony otherwise I'll likely start at 8 grains of Autocomp.
thanks
