I had this scope mounted on a Remmington LTR in .223. Once I found the most accurate hunting load and got everything set up, I was able to easily get 1st round headshots out to 500 yards on groundhogs. The power bezel was not marked for the load I was using, but a light scribe mark made this a very repeatable scope when varying through the different magnification levels. It passed the quad test, has plenty of adjustment, and excellent brightness and clarity. Buy this scope with confidence.
