If your maximum shooting range is 250 yards rather than 100 yards, a 1X to 4X variable power scope as I originally suggested would still work, however, I would prefer a 2X to 7X or 2.5X to 8X variable. I have Leupold Vari-X III 2.5X - 8X scopes on three hunting rifles - a .270 Win, a 7mm Rem mag, and a .300 Win mag. I got my biggest mule deer at over 400 yards with the .270 and the scope set at 8X. Hunting with the .300 I got my biggest elk (a 5 X 5) at about 20 yards (more or less) with the scope set at 2.5X, and, on the same hunt, my only black bear at more than 400 yards with the scope set at 8X. I prefer the lowest power to be 2X or 2.5X if there is chance of encountering the animal I'm hunting at less than 50 to 75 yards.

I may have misunderstood your original post. My recommendations apply to your .270 bolt action rifle. If you are concerned with sights/scopes for a lever action rifle, my recommendation is a 1X to 4X variable. Such a scope would be much better than iron sights.
