One of my (less internet friendly) friends is looking into getting into distance shooting. His range has a 1000 yard max and he is looking into putting an optic on one of his rifles. He is looking into a nice bolt action but for now will be using one of his auto 308s. Does anyone have a recommendation for some glass that is durable, keeps a zero, and priced less than a small country? Right now he is checking into some Leopold scopes, but is using magazine articles as his guide. If anyone has any advice it would be much appreciated.
