shot my furthest dog this morning, twice!

i went out this morning by some feilds i know got some pictures of some elk and turkey's, went down the road a mile or so and seen a dog way out there, about 850 yards out there. i looked at my data and watched him, he started to come closer to a fence in between us and then walked a long it at 700 or so yards. i layed down took a shot hit im back, he yelped and then ran about 50 yards, i then shot again and dropped him. i went out to check him out and the shot was about 725 yards. thats my personal best so far. befor this one it was by holding over at 546 this winter.
