I have a question about rifle ballistics that I hope someone here can help me with.
I have been running some numbers for muzzleloader round ball ballistics through a ballistics calculator, and there is something that I don't understand.
Even though I'm running numbers for a muzzleloader, I see the same thing with centerfire cartridges, just not as dramatic.
Here is the situation:
When I run the numbers based on a 100 yard zero, it shows the drop at 200 yards as 28.5 inches.
But, when I run the same numbers based on a 200 yard zero, it shows the rise at 100 yards as only 17.1 inches.
Should the two numbers be the same. If the bullet drops 28.5 inches between 100 and 200 yards, shouldn't it hit 28.5 inches high at 100 yards if I have zero'd the rifle at 200 yards?
Obviously I'm not understanding something, and I'd appreciate getting educated.
Thanks
