25 to 26 grains of H 322, and a 55 gr SP, Hornady, Speer or Sierra, gives fast velocity even in a short barrel....
The other two bullets I'd use with the same powder or with AR Comp, is a 63 grain SMP Sierra or a 70 gr SMP Speer....
Old School, but they sure hang a job on whatever they hit, even deer sized game....put em in the right spot, its normally DRT for me..
been working just like that for many many decades, for me and other hunters...
