I've always been interested in a scout mount on a light and short bolt gun, might get around to putting one together.
Feedback from what I've read and tried, pros are counterbalancing the lack of weight in a short/skinny barrel and being very fast and pointable, and access to the top of the action. Cons are the image being washed out when you have the sun behind you... and some call the lack of FOV a con but I don't think these scopes are supposed to work that way, ie. it's just a sighting device and you're not supposed to get lost in the scope image.
I haven't used one in the field so take that for what it's worth.
