I've done some googling, but have been unsuccessful in finding graphs of different rounds' trajectories. I'm thinking that it would be good for my understanding to see a chart of a bullet's rise and drop at the various distances.
For example, when trained on the M4, we were told that a 30yd zero is also a 300yd zero because of the bullet's rise from the barrel until it crosses the line-of-aim at 30yds. It continues to rise for a bit, then fall until it again crosses the line-of-aim at 300yds and continues dropping.
I'd like to see a chart for each common caliber to see where they are typically zeroed as well as the amount of drop for longer ranges and bullet weights. I realize this will be affected by the different bullet weights, height of each scopes' rings, and so on... but does anyone publish charts like this?
