Re: why do shots drop more when shooting at a small incline at extreme range?
When I enter incline values greater than 7 degrees the drop decreases as expected, but when the bullet has slowed so much the downhill shot needs less holdover than uphill. I assume it is because gravity is helping the trajectory downhill and slowing the bullet shot uphill. The effect of gravity is almost invisible when comparing incline angles at supersonic speed, but at slower speeds, gravity changes things. look at it this way, the rifleman's rule is explained by the effect of gravity is diminished by the angle because gravity pulls down, not 90 degrees away from the line of sight. Well, when shooting uphill, gravity is not only pulling away from the line of sight but also pulling away from the direction of travel (slowing it down). When shooting downhill, gravity still pulls the same away from the line of sight ( assuming a directly inverted angle, like 6 and -6 degrees) but instead of pulling away from the direction of travel it is now benefitting the bullets speed (not slowing down as much). Another perspective is to look at shot at 45 degrees. Only half the force of gravity pulls away from the line of sight. How much effect can the other have, and at what point is the effect large enough to notice? It is so small that it is imperceptible when shooting a 375 cheytac at 2000. noted. Let me remind, this is only noticeable at much slower speeds, but here of guys doing amazing things with .308 winchester's and 175 smk. Maybe those guys have witnessed this?
