Just bought my first NF NXS 5.5-22x56 and had a few questions on setting the zero. I did not get the "zerostop" feature. I know that the turrets can be re-set to "0" and there are horizontal marks below the turret housing to show where I am on my revolutions. Since I don't have the zerostop, there is the chance that my scope might get "knocked" off it's zero and I want to make sure I know where my zero is so that I can dial it back left or right if something should happen. I've read in the manual that the turret and revolution indicator mark cannot both be set to zero...that's what I was hoping for but apparently not going to happen. I have not sighted my rifle in yet. Can somebody please help me out and give any advice or recommendation on where my turrets should be when I first go to sight my rifle? Does it matter what horizontal mark my turret is set at when I shoot my first group to sight in my zero? Feel free to explain how this works becaues I am new to this. And, it may all be personal preference but just want to make sure I'm doing everything correctly. Thanks.
