I only had a couple of minutes, but I checked zero at 50 yards (It was within .5". I had left the rings on the gun and just remounted the scope and snugged the ring caps down.), then shot from 80 to 150 using mil settings from a previous trip (different scope) that I have saved, pretty well spot on. I just need to tweak the zero. Scope was clear from 25 yards (mounting scope), and 50 yards to 150 yards shooting. The cross hairs are a bit thinner than I prefer, but it isn't a big deal, and it is very usable. Turret lines up perfectly on all clicks, clicks are very positive and virtually no side to side slop, turret is smoother. I'm very happy with it at the sale price now. It's not perfect, and I would take the Tract $1300 30MM LR scope over it any day, but it's a good scope that I'll enjoy using. At $1K it's a good deal on a good scope.
So, whatever Burris did, I need to answer their "how did we do" email very positively, sans the communication, but what the heck, a lot of folks and big companies are bad at that. Results count, so I am giving them a pass on that.
