Do you know where your pellet is going to go when you shoot up?

[UCChris]

I've read thread upon thread on the subject. That is, where do our pellets land when we shoot up at an incline? I'm primarily after pest birds when I shoot airguns, so I have this problem day in, day out. Most of us realize that our pellets shoot higher than our "0°" shooting when shooting up at an incline. But exactly how much has always been a source of confusion. A lot of people just say to shoot at the "0°" distance and you'll be close enough. But does this really hold up? Well, let's find out! Here is a document that I put together to show how my QB79 reacts to incline shooting. The first example is a 25 yard shot (@ 0°) that is shot at a 30° incline. This is a shot that I take almost every time I go to my permission. There is a very tall tree that is 25 yards from my hiding spot that is a quite popular place for birds to land. The next example is just to illustrate what happens when we extend the range.

As you can see, the difference in "0°" POI and actual POI in the short example is a mere 0.2 mils. Not really a big deal. Especially at such a short range. However, in the long range example, the difference is 0.7 mils! At a range of 107 yards, .7 mils is a huge miss!

Anyway, not sure where I'm getting to, just putting this info out there.

EDIT: WOAH, WOAH, WOAH. This may be all bad information! I'm using Chairgun numbers to do these examples. For those of you who use it, you know that you can put in the distance of the shot and the incline of the shot. My question is, should the distance you put in for an elevated shot be the 0° or the actual distance from shooter to target? If I put in the actual, elevated distance along with the degree of the shot, the POI is within .1 mil of the 0° distance. And I've tried four other sets of numbers. So maybe using the 0° is actually accurate???
