My first choice rifle is a .260, that's a kind of moderate rifle, and it wears a moderate 2x7x32 scope. Unless you plan on shooting at night there is no reason to use something with a 50 mm objective. I just bought a Marlin 336 in .35 Remington and am looking for one of the 1x4/5s with a 30 mm tube and no objective bell. That ought to be bright enough or this ol' man.
