You could fire you rifle, and if I dropped a cannon ball at the exact same moment, they would both hit the ground at the same time....
You sir are correct,I stand corrected.
Is this why the .22-250 shoots flatter than a .223? Using the same bullet, the .223 in one second will go 3100 feet, and the .22-250 will go 3500 feet. The drop of the bullets will be the same after one second, but the .22-250 will have gone an extra 100+ yards.
The term "flatter" basically means faster. The projectile that travels faster will cover more distance in the same amount of time. So when you're zeroing this weapon the arch of the projectile path will be "flatter" or have less trajectoryat a given distance, since it hasn't had as much "time" to drop before reaching the target.
There is a really good book that covers all of this info. It is called "Shoot Better II".
I'd recomend getting a copy.

But, that assumes the bullets have the same ballistic coefficient, correct? Isn't it true that certain bullets, even traveling at the same speed and at the same weight, will drop less over a given distance? Or is that because a more ballistically efficient bullet will lose speed at a slower rate? Damn. Should have paid more attention in Physics class...
