I can tell you one thing I'm definetly haveing trouble with my #1 gun I just had to pull the scope off it and send it back to Nikon the dame thing will not adjust up brand new too I put the old Tasco on the new 7400 but I can't get to the range till tommorow (I hope) I don't even know if the Tasco is any good. I checked my Sportsman 78 and it on the Money but I wanted to use my new Auto not my old bolt. But at least I hav a good back up. Going to Maine Sat. the season there starts Monday. I sure hope that Tasco is alright.
