Here is my "yote buster." Its an H&R .223 with a Harris Bypod and Leupold Rifleman 2-7x33 scope. My load consists of Winchester cases, CCI 400 primers, 27.5 grains of W748 powder and a 45 grain Speer SPT. I have just started using this load this year, and have only killed 3 jackrabbits with it. I am getting about 1" groups at 100 yds as long as I don't screw up. I also might have permission to hunt on a couple of hay farms that are over-run with jackrabbits, coyotes, and bobcats!!
