I have several scoped rifles with mediocre scopes. They all work and they also take up a lot of room in the safe. I know some companies make "quick change" rings but I don' know how you quickly change scopes and have it zero'd. I would like to invest in a premium scope but would like to use it on more than one rifle. My experience so far is that every time you move a scope, you have to re-sight it in. Any advice is appreciated.
