I'm looking for a new scope for my 30-06. I currently have a Nikon Monarch 4-16X40, nikoplex? something like that.. anyways. I want something a little more clearer and powerful at distances of 300-500 yds. I'm leaning towards a Nikon Monarch 5-20x44, BDC. Has anyone ever owned or used one of these scopes? My budget is about $600 tops out the door. I'm open to suggestions if you know of anything equal to or better. Thanks!
