Although slightly off topic since I used MOA with a 6.5-20 FFP Leupold ART reticle.
Here is a uncommon doe antelope I shot at 420 yards in a 10mph full value wind using the ART reticle. I originally was going to shoot at 500 yards, but Steve was having a difficult time seeing the view screen of the camera (Glare).
Rear-grip McRee stock, Kelbly trigger, McGowen barrel, Holland Radial Brake and Leupold FFP 6.5-20 with ART. Using the reticle made it easy to handle the changing distances as the animals continued to move.
On a side note we learned it is difficult for the spotter to do his job and try to film at the same time
Used the Berger 140 VLD and it performed great. 1-shot and she was down quickly. Personally I was very pleased how I doped the wind. it was fairly constant and that sure made it easier.
