A couple of years ago I purchased a custom 6mm BR to ground hog hunt with. After finally reaching a goal of killing a ground hog over 300 yards with a .223 I got to break out the 6BR for something more than paper. I am using a 87 gr V-max with 31.0 gr of Varget. Well the first ground hog with my 6BR was at 278 yards. That 87gr V-max was impressive even at that distance. It did a number on that critter. Exploded was a understatement. It is still a pretty accurate bullet too. Next goal---500 yard kill with the 6BR.
