I am going to change some of my scopes to increase the magnification. I'm looking at the Nikon Monarch 4-16X 42mm with side focus. I am primarily a prairie dog shooter. I have a two 4-12 Leupolds and a 4.5-14x. They are fine scopes, but I can get the Nikon for under $400 shipped. A Leupold equivalent would be between $600 and $700. What can you tell me about the Nikon and do you have other suggestions? I plan to stay under $400 if I can. Thanks for the help.
