It's easy to get distance from a range finder. It's also easy to get corrected range for elevation from the right range finders. but knowing where your bullet is hitting at that range and elevation correction is a bit tricky.
OK some are going to say I don't need that, or I don't shoot long distance and I don't need that. But think about it a little. Your sitting in a treestand watching for Whitetail or Hogs. Off to the side you see through an opening the biggest deer ever. At 200 yrds, it's farther than you usually shoot, and down hill. Since it's farther away you want to hold high, but since it's down hill you want to hold low. What a delima, what do you do?
I faced that delima several times and missed many whitetail back when I was a teen. Elevation also caused me to miss a few Mulies and a couple of Elk, in New Mexico
There is only one way to find out for sure, go out an shoot up hill or down hill. Not long distance, just 150, to 300 yards. 300 yards is within the point blank range of most guns and not considered long range by most folks. Once you have mastered that you feel like you have really accomplished something.
Then when the chips are down you miss anyway.
As you may guess I'm still crying about the wolf I missed with the handi earlier this week.
But elevation really throws a twist into shooting real fast. Many of our misses are due to elevation and we don't even realize it is there. I'll be honest here, the Caribou in my avitar was actually missed the first shot. I shot right over it's back. I did not realize the elevation difference from where I was and where the Caribou was. It was walking on the side of a hill, and at first glance you would have thought it higher than I was. But in actually it was below me. I shot as though it was level. That caused my first shot to miss. I stopped, sat back and realized finally elevation was the differance, second shot I held low, right in the boiler room.
