If you have one of the 7 mags (7rem mag, 7rum, 7stw, etc....) get the best scope you can afford. Leupold is tough to beat at their price. You have to spend ALOT of money to get a scope that is clearly better than Leupold. The problem w/ the cheaper scopes on a magnum rifle is that the recoil will break the scope internally(almost cost my wife an elk). If you are useing a 7x57, 7mm-08, the lesser scopes are fine. Good luck
