Not real far but consider the equipment. Many woodchucks at an estimated 300 yards by the amount of hold-over with a Winchester Model 88 in .308 with factory barrel/trigger and full bedded barrel channel topped with a Leupold 3.5-10X scope. Fired from a bipod with a load consisting of a bunch of 3031 behind a Speer 130 HP. It would cut the chucks in half if you hit them in the middle and shot 3/4 MOA all day! I would shoot further but they don't want to come out way out there, I guess I could back up!
I retired that gun, gave it to my son, and have since moved on to "true" varmint rigs but still can't find anything willing to have me shoot at it further, just paper.
