Re: Nikon 4.5x14 buckmaster on 7mm rem mag
If you are using the same load then it should hold zero for you like your shotgun scope does. They occasionally get bumped off but unless you are hitting rocks with it on purpose it should remain where you left it. I would check to ensure that your mounts are good and that all the bolts in the stock, attaching it to the rifle are right as well. Sometimes these get loose and can affect the rifles ability to hold zero. If that doesn't work them I'd call Nikon. You could also mount another scope, if you have one, on it to check and make sure that your rifle doesn't have any issues before you blame it on the scope. Good luck!
