I'm tempted to put a 2.5x Leupold on my .35 Whelen. Mainly I'm liking the idea of how little it will affect the balance and how sturdy it will be. Add a heavy duplex and it would likely be a very good scope for my purposes.
I've comfortably used 4x to 400 yards. Perhaps I could have gone further but I didn't. For the people how actually use these scopes how far are you comfortable shooting with them?
