Hello,
My go to for the 124gn JHP Multi purpose is Accurate #2 at 4GN, 1.05-1.10 COL for most of my 9mm guns, However I make my Beretta 92FS loads to COL of 1.60 as this Just touches the grooves for the rifling. This is my target League Pistol so that\’s why I make the COL so long. Anyway, this is to long for my 3rd Gen Beretta barrel, M9A3, these I make to 1.30 COL due the the grooves being deeper toward the camber.
