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
