OOC: .40 rifle argument

OOC: Yay I so far beat out all of my competition, oh yeah and M41A dude. 10mm = .40 Cal bullets. Meaning your effective range is that of a pistol because .40 cal has a very broad surface area.
wrong a .22 pistol has a short range, but a .223 aka the 5.56mm bullet has a longer range. The range has more to do with the amount of powder and length of the barrel. And .40 caliber is 10.16mm
OOC: I was close enought. And NO YOUR WRONG. Range does have to deal with the length of the barrel and the grains but for the most part the MASS of the bullet. Last time I checked nation states still obeyed the laws of physics and the laws of physics say something with more mass can traverse a greater distance with more energy. Here's an example.

Try to chuck a feather 20 feet at 90 mph. It isn't going to happen because of the feathers surface area and lack of mass to continue the KENETIC ENERGY you provided it with.

Do the same with a rock; and you have a chunk of mass flying at 90 MPH until;
1. Gravity Yanks it back to earth
2. 3rd Party Object gets stuck in it's path and takes the energy says Newton's law of inertia.

Now heres the relation of that example to bullets. The lighter one, the .223 Hornet bullet would have a good range but because of it's lack of mass it can't have the possible amount of range as well as joules of energy the the 5.56 or 7.62 bullets CAN have.

Look don't fucking talk to me about bullets. I'm a gun junkie KTHX.
"WRONG. It was done by a Candian sniper team with a .50 BMG round. The bullet was in the air for 3.76 seconds before it raped it's targets face. STFU.. This kill was done with a Cheytac LRRS."

2. The current record for longest range sniper kill is 2430 metres (7,972 ft), accomplished by a Canadian sniper, of the third battalion Princess Patricia's Canadian Light Infantry (3 PPCLI), during the invasion of Afghanistan, using a .50 BMG (12.7 mm) McMillan bolt-action rifle. This meant that the round had a flight time of four seconds, and a drop of 44.5 m (146 ft). The previous record was held by Carlos Hathcock, achieved during the Vietnam War, at a distance of 2250 m. -wikipedia

Mass has nothing to do with range. In fact, a smaller mass will be able to move faster and farther with the same propellant as a larger mass. The reason a feather floats the way it does is due to the obscene surface area granted to it via the thousands of little hairs covering it. For a good experiment, throw a peice of flimsy sheet metal the same size and shape of a feather (slits and everything). It's not going to move very far either.

"I don't see what the arguement is.. Your just re-instating exactly what I said; the bullet was in the air for about 4 seconds, or 3.76 seconds and it was done with a .50 BMG bullet. The only thing I got wrong was the gun. =/"

So no, for a larger mass and more aerodynamic bullet the larger massed bullet would win. Range is a mixture of aerodynamics, mass, weight, bore, grain, and size... The .40 rifle round isn't nearly as aerodynamic as say a 5.7 AP round as it has a much larger surface area to act against making friction a huge problem. While the 4.7 FMJ or AP would be able to traverse about the same distance if not longer because it is nearly frictionless... http://img.photobucket.com/albums/v145/KGBFaTaLsHoT/fn_p90.jpg look at that bullet in comparison to your larger though more 'ball round' bullet."

one of the most accurate sniper rifles in the world is the CheyTac .408

"The MOST accurate sniper rifle in the world and still holds it's title..."

The Mauser SR 93. Only 297 were made due to it's expenive manufacturing cost and poor sales. At 30k a peice it damn well better be the most accurate.
