Don’t put the new scope on another gun to prove it just yet. First Put the old scope back on this gun and shoot the gun again. If the groups tighten up it is either the newer scope or the way you had it mounted. If the groups stay opened up with the original scope(when you say it shot well) then it is obviously something else with the rifle itself and maybe not the new scope. Not really sure how this would happen with just a scope swap though?
