I built this rig a couple of years ago, chambered in 30-284 and use it for long range deer and coyote, shooting Hornady's 155 gr. A-MAX at just under 3,400 fps..
I shot this mangy coyote at a laser ranged 812 yds....
I shot this little guy at 1,062 yards. No wind, overcast sky and perfect shooing conditions.
