Re: Success At +1000 yards!
The Wild coincidence rangefinder has an adjustment to correct for known distances.
We calibrate them and the Barr and Stroud off the target frames (1000 Yards) at Williamsport all the time.
You can set your rangefinder up for "your" rifle only and do actual fire test at the ranges the rangefinder says it is. Make a drop chart for that rangefinder only and it will work just fine for you.
For instance, if your rangefinder says something is 2000 meters and the known true distance is 1500 meters, if you have fired for effect and made a drop chart to match the hits on the targets of the rangefinder and what it read, you will be on target at 1500 yards. Remember, that setup is for your rifle ONLY. If another person tries to shoot what the rangefinder says it is, with his rifle, he will put 2000 meters of clicks on and shoot way over the target.
It doesn't matter what the rangefinder read as long as you have fired on the target you were rangeing and hit it while making the drop chart.
We once had a Zeiss military rangefinder with no adjustment for correction that worked correctly. We made our own drop chart to match the readings for "one" of our Longrange rifles.
