I cannot remember taking a deer in the brush beyond 50 - 75 yds. And the ones I have taken were moving.
I use a Marlin 336 for that type of hunting. If I'm going to be hunting a stand which might present longer shots I'll select a rifle better suited to the task.
@Bigun That's right up in here too... I am a water hunter... I have done a blind in a meadow some, but I get better control knowing where the critter I am hunting goes to water, because they always seem to get on a trail to do that. Then I can park in a blind at the pinch point in that trail I choose and always get a pretty good chance. I don't care much for heads on the wall, so I generally do a head shot and drop em in their tracks... If they run at all, the adrenaline taints the meat...
So yeah... In the brush, or even in a mountain meadow, say, 50-100 yards. Very rare to have sight lines longer than that.
Now going for elk or sheep, and certainly goat, That's a different thing. There you are probably going above or at the treeline, shooting across between mountains... That's all going to be the big iron and say, longer than 400/600 yards. There I will wait for a side shot behind the shoulder...
Between those two scenarios, the window say, between 200-400 yards, I rarely get shots in that range. And I really ain't geared for it. I can function to 250 or so with a ladder sight on a lever gun... But not like I used to. And I could maybe dial a scope down that far, to cover maybe 300+, but I would probably pass on the shot, really.
