Its good to go out to 300-350 yards with the right bullet.
Its killed Elk and Black bear so its got ump. A 5X Elk was killed with one at about 350 yards in Colo a few years ago. That said ours gets used mostly out to about 100-150 yards.

You should be able to hit 3/4" with the right load, but thats about it with an AR without match components IMO. Mine shot about an 3/4" - 1" and so does the mini.

I chronograh all my loads if you want them, but none are accuracy loads.
