The Shepard scopes are great quality and they work just exactly as they are supposed to. Find the range set and thats where that bullet is going to hit. My Buddt took a Pronghorn this fall with his. The range said 428 yards. He set it and hit the animal in the neck. He then checked the distance with his lazer range finder then stepped it off as well. He is impressed with it and he is hard to impress. ME? I can't afford to even try one.
