A couple of years ago an air rifle magazine editor wrote that pellets fly upwards after leaving the barrel before starting to fall. I wrote to him to point out his error and he defended what he'd said and refused to publish any clarification - I think he was too embarrassed. Earlier this year an article appeared in the same magazine, written by a very experienced shooter (who frankly should have known better), making the same statement. I wrote to the now new editor and pointed out the error: I didn't get an acknowledgement. I then wrote to the editor in chief and didn't get a response to that either. So then, just to clarify matters: In order for a horizontally launched object to rise, it needs lifting surfaces ("wings"). Pellets don't have wings, they don't rise. As soon as a pellet leaves the end of the barrel gravity causes it to start to drop and the further it gets so the rate of fall increases (being the cumulative effect of gravity). You can also add that as velocity slows so the rate of fall increases. I think a lot of shooters have gained the wrong idea simply because they use Chairgun which represents the image visually as the pellet rising and then dropping. I accept this is really the best / easiest way to represent the issue. Basically it's because we look through the scope in a straight line. The scope is mounted above the barrel therefore the line of the pellet and optical line through the scope would never intersect if the scope was set in a true horizontal plane. But we need the two to intersect to get our primary zero so we angle our line of sight downwards, by using the adjustable reticle. Thus, bearing in mind the pellet is falling, there will be two points of intersection (primary and secondary): but this is not caused by the pellet flying upwards "into" our line of sight, rising above it. then falling through it again, as Chairgun would seem to indicate. I spoke with the writer who had made the claim in his article and he maintained that pellets do fly upwards because barrels are angled upwards. A bit of thought tells us that if barrels are angled upwards, or the bore is somehow angled upwards, then the barrel is not actually horizontal. I checked this claim out and found that some target rifles actually had the scope dovetails angled (by 0.02 of a degree I seem to recall) in order to reduce the amount of adjustment necessary for the shooter to make to the scope. In other words the manufacturer is not angling the barrel they are angling the scope. I feel better now!
