Chris,
I have never mounted a scope that I could not hit the paper at 25 yards. I was reading some of the bore sight reviews over at Cabela's and the 60 dollar ones sound questionable at best. If I were you I would not waste my money. If I were serious about ownning a bore sight I would probably start my search at Brownell's. A good MOA chart might assist you as well.
Happy shooting,
Neo
