I dial every time I shoot it. I think it's 8.4 mils @1k with a 210 Berger around 2850 fps @ 300 ASL. I haven't sat down and compared it to my SB, but the glass is good and for sure will get you to 1/2 hour after sunset. Like I said, I don't have thousands of rounds through it, but so far so good. I got it for $1120 on a black Friday sale, and for that price it is a steal.
