I'm looking for a better riflescope than what I have now (Tasco World Class 3x9x40)and I've been looking at the Bushnell DOA 250 and 600. I shoot a single shot New England firearm .270. The DOA 250 comes in the Trophy series. And the DOA 600 comes in the Trophy, Elite 3200 and 4200. I want a wide field of view. I would never shoot 600 yards and the fields that I deer hunt are no more than 250 yards. I like how the 250 goes in 50yd increments but the 600 may be what I need. Have anyone ever used the Bushnell DOA riflescopes? I'm going to stay with a 3x9x40.
