My wife just bought me a Vortex VIPER 4-16X44HS LR for Christmas,I'm going to be mounting it on a DPMS SASS. I need to know can any one give me any sighting in advice on this scope,I will be shooting up to 300-400yrds the elevation is 1/2clicks and windage is 1/4clicks will those type clicks effect me from making accurate bulls eye hit on targets at those range on paper? If so what are some solutions to bring my POI closer? What will be my Point Of Impact at 1000yds? If any of your guys have this scope mounted pls post pic I would love to see your scope and ring collaboration.Is there any type rings i can purchase or any scope tricks i can do to make the 1/2click become 1/4click if wanted to do so with out getting another scope? if so please explain.
