I once tried shooting downwards, about 45deg., in an incline at a target. Somehow I could never hit where I wanted to. Then I met a friend who is an engineer,as also a member here, and explained to him my predicament. Simple, he says 'its the cosine'. So he explained the funda and I tried it out. It worked! Now I don't quite remember the mathematical formula, as I almost plugged my maths in school, and never had a liking for numbers unless they were the monetary kind , but I got the gist of figuring trajectory in a downward incline. Its quite similar to shooting into water when your target is underwater. The prism effect, in reality.

OUCH! My head hurts too!

I do not know if this would ever have an effect with high powered rifled though, other than for benchrest accuracy or long range hunting in the mountains.

Where it does make a difference here in North America is when bow hunting from a tree stand. In fact, there are special tree stand sights that operate on a pendulum principle.

Here is a pic of a sight with the aiming pin "unlocked":


you can also lock the pins on these sights so they work normally, but hopefully this will help a person better visualize the geometry of what happens when firing on an angle, much better than a couple pages of figures can!
