I just use my GPS for the distance. Mark target and head out. My 1000 yards was actually 997 yards from barrel to target. Close enough to 1000. Thank God I have a place to drive to ( 40 miles away) and shoot out to 2 miles. Man would that be fun and impossable. 1200 is the farthest I have gone so far. It is more fun then one should be allowed to have.
Wind flags are almost better than the hand held's are. You can place them every 100 or 200 yards. hand held is just good for where you are. I have found that wind changes in 1000 yards. This is standing at target Way in the middle top is a 12 x 16 deer stand. I am laying in the grass next to it
