We have decided to shoot in fifty yard increments instead of 100 yard increments for our drop charts. Idea is to simplify our estimates when cranking up for an animal that is between the hundred yard distances we have zeros for. We get a lot of drop with our .308 Win. rounds so I believe the fifty yard increment will be usefull. We restrict our shots to 600-700 now (that is how far we are confident in our ability to hold a lethal sized group in most wind we hunt in - plus the Leica 1200 is very reliable at that distance). Since our drop cards only go to 700 yards this will not make for too much complication, we start at 300 and will go in 50's to 700. We recently had shots on bucks at in-between distances and had the correct wind on but missed the elevation estimate and hit just high on two or three occasions - that is why we are going to shoot 50 yard increments. Since we don't create charts from a computer program we will simply do more shooting to get these come-ups. Interested to hear if other guys use fifty yard increments in their drop charts.
