Our longest range her is 200 yds. but I get to the woods some times and hit 6o0 to 650, the 200 yd. shots are in a 1' GROUP the 600 were 6+ inches trying to adjust the Boss on the BBl. can be a headache. The mod 70 has a older Redfield 3by 9 scope , great optics for the era! Super CLEAR. Check evil bay for a LE 3by9 redfield, they are about the best for ANY 3by9!
