    I used these rounds a couple of weeks ago hog hunting. 2 bullets fired, 2 hogs down! 97 lbs and 104lbs. Good head shot placement. They both went down immediately, didn't even take one step.

    This is an amazing load out of a 9-inch Sig MCX pistol. Ran 10 rounds at 25 yards in less than a inch diameter, at an average velocity of 2150 fps with energy of 1129 ft-lbs - this load is why 300BLK is THE thing to run in your AR pistol/SBR.
