I'm not to surprised, I love my Nikon rifles scopes but pistol scopes are another story. I went through 2 of them on my 15" 308 shooting 150gr Noslers, the first one failed after 3 shots and the second one after 10 shots, and both looked just like that. I think it was a bad lot because the serial numbers were only 3 digits apart but I didn't want to try another one.
