I don't know much about optics. I have a 308 with a lousy scope on it. I need to put a scope on it but the reality of it is I will never reach out much more than 100-150 yards. It will be my new deer rifle for a couple areas I could not hunt under former laws. I cannot afford to buy a high end scope. Is there a functional scope out there that can tolerate the recoil of a 308?
