Query: Clarity unacceptable after 100 yards

I bought this spotting scope to use with target shooting and rifle sighting. The scope is clear to 100 yards, but the optics really suffer at any longer range. At 200 yards, the focus is slightly blurry and I can't even make out individual lines on a paper target. This is really unacceptable for a spotting scope--I'm returning this item.
