As a result of the questions I had in a previous post on tactical scopes, and the great responses I got from you guys, I've really narrowed down to what scope I want on my new rifle. It's the 4-16x50 Nikon Tactical. I've read some great reviews on it and it seems perfect for what I want to use it for. I do have one concern though that hopefully some of you can help with. This particular scope is rated at only having 50 MOA of adjustments from top to bottom. A great review at snipercountry Nikon Review at SniperCountry showed that it actually has 70 MOA of adjustments. Definitely better than 50, but still considerably less than the competition. Should I be concerned with this limited adjustment capability? Although the rifle (7mm Rem Mag) is still being built, my plans are to shoot the 175 SMKs at about 2800 or 2900 fps out to 1000 yds using 20 MOA bases for the scope. I guess I could use a program to figure this out, but wondered if any of you had real world experience with this particular scope and its actual runout.
