Yes, but the beam devegance may be bigger that a groundhog at 400 so you will be getting some ground wth it. The best way to fight that is get ar far above te target as you can. This will allow you to range at a downward angle and increase accuracy of the rangefinder. Also you will need to rest the RF on a tripod or solid rest to be accurate on such a small target.
The Swaro Laser Guide 8x30 and the Leica CRF 1200 are the two current modles that are up to the task and more. I would also assume the new Zeiss 8x26 would do it, but I haven't tested it yet.
