Historically I've used scoped rifles for anything longer than 100 yards'ish. In just target shooting or hunting. Although more recently I acquired a couple old WW2 era rifles (not sporterized) and I was surprised at what I could do with just irons at 250 yards. I haven't had a chance to shoot longer yet with those rifles. But the scenario got me thinking and scheming. It might be kind of fun to hunt with a 75 year old rifle and iron sights. . . . I'm sitting at my computer thinking this is great. But in reality if it's getting dusk and I can't see clearly what the deer is, I'm really going to be wishing I had that scope to give me the 15 more minutes of hunting.
