I would feel comfortable at 150 better at a 100. Longest shot I ever shot at a deer (doe) and connected (One shot kill) was a couple of years ago with my Marlin GG 45/70 a ranged by two range finders 190 yards. I felt comfortable with that shot as I was using a rest and the gun is scoped with a 1.5x4. Weaver scope. I also ahead of time figured out the trajectory and the hold over. I was sighted in at 100 yards. With the load I was using I held a foot over her back to get it into the lungs heart area and it went through the front leg and through the heart and out the other side. If I would have had my Winchester Model 94 I don't know if I would have taken the shot or not. I consider both my lever guns woods rifles. I have a Swedish Mauser 6.5x55 with a scout scope set up for long shots.
