Greets,
I do not, however the guy I hunt with has had one on his .270 since before I met him, that was 6 or 7 years ago. He loves it, its a 3-9x40, he regularly takes target shots out past 400yds, and took his deer 2 years ago at 400+. I say for a low end scope its a damn fine one.

Just my uneducated opinion!
