First bad, burris scope - Burris Fullfield IV 2.5-10x42 mm 1in Tube Second Focal Plane (SFP) Rifle Scope

I mounted this scope on a Ruger X22 Carbon Lite 10/22. I sited it in at 25 yards. The scope was great. When I moved out to 50 yards, the center of the scope would start to blur at 6x magnification. By 10x, you couldn't identify the paper target. The blur was 25 to over 100 yards. I called Optics Planet, and they helped me get the scope returned to them for credit. I also ordered another scope while I had them on the phone.

I have to add that I own 6 Burris scopes, and I am a Burris fan. This scope was the first that I have ever had an issue with and a very rare occurrence.
