Guess I'll make my first post here. Glad to see that you are getting interested in long range shooting. I for one am not the biggest fan in holding over, although it can be done with a Mildot reticle, it is a little less precise to use that over a hold-over reticle. If you look at what the tactical/long range crowd are doing more often than not it is dialing in the adjustment. There are a boatload of how-to's on that subject, just do an internet search. You stated you wanted target turrets on your new scope, what better use to put them too than that anyway?
Nikon makes some pretty decent glass. I've heard more than a couple of rumors about their CS lately. The other thing about Nikon is that most of their scopes are rather limited in internal adjustment. In their Monarch line you really have to drop down to the 3-12x to get enough internal elevation adjustment to get you out to any real long range distance. The Monarch Gold has enough, but maxes out at 10x and the Monarch X 2.5-10x is in the same boat. Not that 10x isn't enough at 600yds because it is. A lot of shooters though prefer more magnification at that range. With an angled scope base with 20MOA of adjustment you are taking out the possibility of a 100yd zero with the entire line above 4-16x, and even that one you have to be dead on (40MOA of internal adjustment).
You never included a budget of what you were looking to spend or keep it under. IMO if you are in the area of the Monarch's range of $400-650 depending on the model you might want to look into a couple of other scopes. I've got the chance to look through, and am now on the waiting list for one of the new Sightron SIII's the 6-24x50mm with mildot and target turrets and 100MOA of internal elevation adjustment. The glass is every bit as clear (maybe even better) as the leupy Mark 4, but the SIII runs about $790 street price. If you can't afford that then there is the Bushnell 6500 2.5-16x42mm at around $550 with the mildot again and 80MOA of adjustment. It is a toss-up on glass quality between the 6500 and Monarch, but I doubt you will be disappointed. The only bitches and complaints I've heard about Bushnell are a couple about CS, just like the Nikon's. Want to spend less than that? If you are just punching paper or ringing steel the $300 Super Sniper is a good optic for the money, I've owned the 16x SS, and had no complaints.
Which ever way you end up going good luck, hopefully I've been able to help a bit.
