yea i know but doesnt the force behind the bullet cause it to have horizontal accelartion? The force of gravity is the same no matter what I know that but I do long distance shooting and I have fall off charts that say my 50 caliber Barret round wont drop off until around 6000 feet? It does drop of a bit before that but it is so miniscule its unreadable so in effect doesn’t the bullet have to travel at insane speeds in order to reach the fall of distance to match the dropped bullet?

Yeah, and that is why the bullet being shot ends up so much furthur away, is because it has a horizontal acceleration/velocity and the other does not. Hitting the ground is dependent upon their vertical accelerations, and they are both the same. You could figure it out mathematically too.

edit: (Just saw the second part) Yeah it does, and I think thats why its so hard to comprehend. I mean if you drop a bullet it takes a second to hit the ground, so I guess the one being fired is travelling 6000ft/second. (obviously im not being accurate, but you get what im saying)

lotas, that's with a perfectly flat trajectory and equal resistance, which isn't going to happen in normal daily applications.. for what it's worth.

also, you meant "farther."
farther refers to distance. further is more figurative.
uncomprehendable would also more accurately be said as "incomprehensible."

and with a Barrett light .50 you also probably need to factor in the curvature of the Earth when calculating a flat rajectory. You're talking about a rifle with an accurate range of over 1000 meters.

It's one of my favorite rifles. My best friend was an army sniper and carried one in the service as well.

Knew that was coming

But hey, learn something everyday with Kiki.

Wow Im surprised anyone has heard of Barret I personally use the model M82A1 its incredibly accurate at very long distances. When you shooting a weapon like this there are so many things to consider just like kiki said. I was going to go into the army as a sniper but I couldn’t get in because of health issues (busted knee). http://www.barrettrifles.com/rifles/rifles_82A1.htm

the bullet thing i cant buy into in daily real life situations. too many variables, trajectory wind speed and direction.

but the airplane thing. now thats another story, if you have ever been on an airplane and seen the stewardas come from the back of the plane to the front you would know that they are running at least 500mph just to make it there.

Damn...that Barrett rifle is taller than my grandma.

And yea...Smoker, have you considered becoming a comedian or something? You def come up with some funnies my friend!

I could tell ya some interesting facts about the rounds teh military has available for the Barret, and what they do to a person upon impact..
scary stuff.

Not the sort of weapon you can just "wing" a person with. Pretty much any hit is going to be a fatal one.
