I had one of that model and 2 3.5-10's that wouldn't reliably track. Recently had a 2.5-8 that had groups open up; was good for 15+ years as a set it and forget scope on a 35 Whelen that saw a lot of shooting and use.
But if you have any doubts, I'd throw a known entity scope on it. Or try the scope in question on a known entity rifle.
