I'm seriously considering spending the money on a Nightforce Scope with "Zero-Stop" but I'm wondering whether I'm right about one of the things I want to use it for: As I understand it, "Zero-Stop" (among other things) will make it much easier for me to use the scope on two different rifles. My thought is that I can 'zero' the scope on one rifle (with a QD mount), set the "Zero-Stop" and then move it to a second rifle- once mounted on the second rifle, I can keep track of the 'clicks' it takes to move from the 'Zero-Stopped' setting to zero on the second rifle. That way, any time the scope is mounted on rifle 1, I can simply use the Zero-stop feature normally; and when the scope is mounted on rifle 2 I can simply dial up 'zero' from the "Zero-Stop" setting and use the scope like any other that doesn't have "Zero-Stop." Is this a reasonable scenario? How does the "Zero-Stop" feature actually work? I mean, let's say I have the rifle zeroed and I have it set into the Zero-Stop feature- when I make adjustments for a particular shot and want to return to 'zero,' do I push a button or twist a knob or what?
