I am looking at buying a scope for the Remington 700 SPS I will be buying soon and I can not figure out what would be best. I have a limited price range right now and it will be like that for some time but my price range is $300 to $400. I know I will not be able to buy a great scope but I am looking for something that I will be able to shoot out to around 400 yards with. Any recommendations?
