RE: Nikon vs. Leupold
Another vote for Nikon. I've had a couple Buckmasters and slowly replaced them with Monarchs. I just got my hunting buddy to sell a Vari-X III and replaced it with a Monarch.
They are clearer than Leupolds (IMO) and a lot less $$$$.
The Buckmasters are a great scope. You won't be disappointed. If you don't buy that scope from your friend tell him I might be interested!!!!!
