.223 vs 5.56x45 accuracy

[kb2wji]

A bullet dropped from your hand will hit the ground at the same time as a bullet fired from a muzzle parallel to level ground. Science is amazing. This is why we "throw" them "up" with the barrel. How high you throw it is up to you. RT is right - for precision shooting, you will need to know the bullet path.
For combat or "point blank" shooting, a good zero is "good enough" - especially with the relatively flat trajectory of the .223/5.56x45

I'm clear on the acceleration of gravity, but It's still pretty neat to think about that. It only takes a second or so for that bullet to hit the ground after it leaves the barrel. Really puts the speed of that sucker into perspective. :D
