gerrygoat,

My guess is that 8x will work fine on your .264. One of my own long-range rifles is a 6.5-06, and it has a fixed 10 Leupold Mark 4. Just as my wife has never had any problems "finding" deer even at woods ranges with 8-10x, I've never had any problem with 10x at typical open-country distances.
