Ok another possibility, and the most likely answer...
thinking it's slag

so until I get the results back..
I'm going out to hunt for something else...

That sounds like a worthwhile endeavor.

Hematite
i can't stop looking this up...last one...
another possibility...? color difference tho.. (mine is the closeup)
Hematite
Fe2O3
An iron oxide mineral, hematite is commonly metallic gray, brown, or reddish in color. It is an ore of iron and can form naturally in sedimentary, igneous, or metamorphic rocks.

about the weight...
so if it's not an iron meteorite (which i'm pretty sure it's not) then it
could be, as I said earlier a chondrite or stone meteorite, that would explain
the weight.
recap...and I've added these pictures of mine again for reference...
TYPES: A meteorites type typically refers to the 3 main groups of meteorites
• IRON (Nickel Iron, Octahedrite, Siderite)
Iron meteorites are very dense, 7-8 g/cm3.
• STONE (Chondrites)
Most meteorites are ordinary chondrites, and ordinary chondrites have a density half as much. Most ordinary chondrites are in the range 3.0 to 3.7 g/cm3, which is denser than most terrestrial rocks. For example, limestone (2.6 g/cm3 or less), quartzite (2.7 g/cm3), and granite (2.7-2.8 g/cm3) are all common low-density rocks. Some meteorites have low densities (<3.0 g/cm3), but such meteorites are rare among meteorites.
• STONY IRON (Pallasites & Mesosiderites)
possibilities.....

possibly could be slag, here's some pictures of slag:
http://www.meteorites.wustl.edu/id/slag.htm
but slag has that swiss cheese thing going on..and it looks really melted but I guess it's possible...but i'm not 100% on that one..

I don't think it's Pyrite Concretion...

I doubt it's Magnetite, not magnetic enough..
pics: http://www.bing.com/images/search?q=magnetite&FORM=HDRSC2
and paper clips would likely stick to it

i'm going with team • STONE (Chondrites) vs. just an earth rock
let's see who wins...
pics of chondrites..(so many variations)
http://www.bing.com/images/search?q=STONE+Chondrite&FORM=HDRSC2#a
They are divided into three groups, which have different amounts of metal and different amounts of total iron:
H chondrite have High total iron and high metallic Fe (15–20% Fe-Ni metal by mass[23]), and smaller chondrules than L and LL chondrites. They are formed of bronzite, olivine, pyroxene, plagioclase, metals and sulfides and ~42% of ordinary chondrite falls belong to this group (see Meteorite fall statistics).
L chondrites have Low total iron contents (including 7–11% Fe-Ni metal by mass). ~46% of ordinary chondrite falls belong to this group, which makes them the most common type of meteorite to fall on Earth.
LL chondrites have Low total iron and Low metal contents (3–5% Fe-Ni metal by mass of which 2% is metallic Fe and they also contain bronzite, oligoclase and olivine.[18]). Only 1 in 10 ordinary chondrite falls belong to this group.

I still don't have my hopes up too high, I'm pretty sure it's just something else...but, it's been interesting...and really educational.

That is one neat find! I would love to think it is a meteorite, and it very well could be. But trying to think of anything else, could it be "coke" from a metal or steel making facility? I found a rock that looked similar to that, but only about the size of a golf ball, and was told by a veteran MDer, that it was a piece of coke.
They are often found around railroad tracks, and steel mills, and sometimes old homesteads. I'm certainly no expert, but it has something to do with coal being burned and I don't know. I guess you could look it up.
But what I found was heavy, registered as iron, and a magnet would stick to it. Not saying that is what you've found, but a possibility.
Good luck, and I hope it is a meteorite! That's a lot more exciting, and possibly valuable!

where it sat
It would be funny if this rock turns out to be something, I've been looking at it for a long time, thinking it was just a cool rock.. this is where it sat for quite a while..the other rocks were found in the same area..
i'm not keeping it at my house any more just in case...hahaha..

Glad to hear you finally got a qualified group of folks to examine it! Great rock for the rock garden anywho!

Sorry it's not the real deal. You definitely learned a lot from your research about rocks, minerals, and meteorites.

Bummer! At the very least this has been an entertaining thread for me but darn it!
