The uphill versus the downhill shot is probably the biggest bone of contention around the campfire. Science has an answer, but it does not ring true and at first glance it looks like the wrong answer.
And it is well nigh impossible to test it in practice, because there is no shooting range with an uphill and a downhill range. In the veld the conditions are not ideal, bacuase there is no shooting bench and it is impossible to accurately determine the angle.
Science has it that the uphill and the downhill shot are exactly the same, because it concerns the horizontal distance the bullet has to travel. The theory is that the bullet travels a shorter horizontal distance when shooting downhill and, therefore, one should aim higher for the shorter distance. The steeper the angle, the shorter the distance. The attached diagram is based on an angle of 30°. It the gun is zeroed at 200 m, then the aim should be set as if the buck is standing at 173 m. Therefore, the aim is set lower. Uphill and downhill remain the same. At 45° angle the horisontal distance is 141 meters.
Bulldust and poppycock, says my hunting partner. Nico Steyn, a man with a maths degree, you have to aim lower against the uphill, because the buck is facing you at an angle. The angle exceeds 90°, but the aim is directed as if the buck is standing at exactly 90°. The buck will be hit where the aim is, but because the angle is greater than 90°, the shot will pass above the organs. Should the buck stand on the downhill, the angle is smaller than 90° and tha aim should be lifted to prevent shooting underneath the organs, See Nico’s attached sketch.
Be that as it my, I’m sure there are many theories floating around. Therefore, we are inviting readers who have investigated this science to air their views.
