I forgot to mention your dot. Is it a 3 MOA device?
From the photo, he has an UltraDot Match Dot, so he can select among 2-4-6-8 MOA dots. I agree he should be using the smallest size available.

As I mentioned in my earlier post, even though they don't magnify, dot sights can suffer from varying amounts of parallax error if the dot isn't centered in the scope. I checked, and the Match Dot is optimized for 25 yards and can have parallax error of up to about 1/2" vertically and 1" horizontally at 50 yards (good discussion of that here), so it's important to be sure it's centered. I know of some bullseye shooters who use a white or yellow rubber band, the kind that they hold lobster's claws closed with, around the ocular of the scope to help with that - I believe it's something that Brian Zins recommends.
