I have a FXII 6x36 w/ LRD reticle on my Tikka 270 and it works fine. I jumped this years mule deer while he was laying in the sage brush at about 30 yards max, no problem finding him in the scope and dropping him in his tracks.
In the past I had a FX-III 6x42 on a T3 30-06 I used to own shot several whitetails at under 60 yards, the only time I wanted a lower power scope was shooting pigs that jumped up at less than 15 feet...but most likely any scope would have been too much at that range
