As has been said above good optics make the difference of hitting or not at long range with heavy recoiling calibers as well as extending the daylight. If you have never used great optics at distance ,there is no way that I could convince you that the cheaper lesser cost optics that may work at 100yds. will be found wanting at a 1000yds or farther and will come apart with 300 win or 338 lapua recoil let alone firing 50BMG. I realize cost is a factor for many of us but if youcan afford the better optics you will never be sorry you bought quality.
