RE: which scope
i have a conquest 3x9x40 in the z-plex and i absolutly love it......,best glass for the $$$ IMHO. If it were me, with a flat shooting .257wby, i would opt for the 4.5x14x44 conquest, its another $200 or so more than the 3x9, but thats only about 3 boxes of factory loads for that hot rod!!!!!
