Simmons, Bushnell, and Tasco, to name some of the better known, "less expensive scopes" have come a long ways in just a couple years, trying to compete for that market for a scope that will get the job done, and be affordable to those who don't want to spend money on a premium grade scope.
I've had good luck, so far with Simmons and their latest entries in their Master Series, such as the "eight point" have been dependable and hold their zero.
You shouldn't have any problems with the light recoil of the 25-06!
