So it appears I will have a late rifle elk tag this fall. I am a real dummy when it comes to rifles and scopes. I have a .270 with a really cheap scope on it. I’m assuming a upgrade is necessary. What scope do I need? not sure what magnification or objective would be adequate. How far should I be able to shoot, 500yds? I’m not looking to buy super high end. I realize you get what you pay for.
