My Rugers shots patterns, not groups...
Until I stumbled upon one last load to try out of a Hornady manual...
40 grains of 3031 with the 175 grain RN....
Half inch group! didn't believe, thought was a fluke, went home and loaded
some more , this time some with the 175 SP instead.. same 1/2 inch groups..
book said MV should be 2450s fps...chronograph seemed to disagree, and came
in at 2650 fps....so did a friend's Oehler...
brass didn't seem to think there were any pressure issues..
same 40 grain Charge of 3031, worked the same for accuracy with 160 down to 139 grain
bullets also...so you can guess what the Ruger digests....and what powder is all it is fed.
