I have worked up a load using 41.5 gr. of H380 and Winchester standard primers and Winchester brass. 2.640" in my Remington SPS 1:9 1/8 twist and getting 3/4" 5 shot groups at 100 yards so far. I have bought fed magnum primers and going to ladder step it up and down to get the best possible accurate load. Haven't shot a coyote with it yet to see how they do but hopefully today or tomorrow I will get a chance to do that.
