Here is a picture from June of this year, taken outside Lamar, Colorado. 615 yards measured with a Leica rangefinder. The rifle is a stock DPMS AR in 223 with a Mueller scope on top. Load was a 40 grain VMax with H322 powder and Wolf Magnum primers. I shot several of them in the same area. As you can see in the pic, that tiny bullet still has enough to get-r-done at 615 yards.

To keep things honest, I never do the measuring. I walk out to the dog (best to do this with 2-way radios), hold it up and have someone else range it several times from my bench.
