That would be a no to Walmart then.

Walmart sells ammunition - cartridges.

A cartridge is made up of a case, a primer, powder, and a bullet.

If you want lead - check with plumbing supply stores and with gun stores.

Gun stores sell shotgun shot - lead pellets and lead bullets.

Teck's Ass lol

[quote="Jdurg"][quote="sniper"]Is it the more the actomic number the more dense it is?[/quote]

That's not neccesarily true. Tungsten, Gold, and Platinum are all much denser than Lead but they have a lower atomic number. Also, Bismuth is actually less dense than Lead by about two grams per cubic centimeter. The list of elements denser than Pb are as follows:

Element (Atomic Number)
Technetium (43.)
Ruthenium (44.)
Rhodium (45.)
Palladium (46.)
Hafnium (72.)
Tantalum (73.)
Tungsten (74.)
Rhenium (75.)
Osmium (76.)
Iridium (77.)
Platinum (78.)
Gold (79.)
Mercury (80.)
Thallium (81.)
Thorium (90.)
Protactinium (91.)
Uranium (92.)
Neptunium (93.)
Plutonium (94.)
Americium (95.)
Curium (96.)
Berkelium (97.)
Californium (98.)

The denser elements on the periodic table tend to fall in the central portion of the table. As the f-orbitals begin to fill, the density of the elements with the full f-orbitals increases as the subsequent d-orbitals fill. When the d-orbitals are filled, the density then begins to decrease. Lead falls on the decreasing density slope as it has a full f-orbital and a full d-orbital. I believe this is the trend, though I may be wrong as I'm going by memory here.[/quote]

nice list

Wal-Mart

Actually you could have gotten lead at Wal-Mart after all. Pellets for use in BB / pellet guns are usually made of lead, just like bullets. Fishing sinkers are, too. Solder is available at Wal-Mart, and you can find high lead content solders there (probably with a variety of non-lead solders as well.)

Bullets are alloys, usually with Nickel (something to make it harder)....you can by just bullets by looking in the blackpowder/muzzeloader section (old fashioned rifles where you manually load the bullet and powder etc)

Solder is only about 60% Pb, the rest is tin (starting to phase out Pb as Pb is bad stuff, replaced by a Silver alloy)

They mine lead about 50 miles east of here (in Missouri US), its the lead capital of the world = lots of backwoods retards surrounding the mining areas...TOO MUCH LEAD IN THE HEAD!

Back to your original question....
Density is determined not only by how heavy/dense the atom itself is, but also by how the atoms pack in crystals. Different crystal arrangements have different "packing efficencies" / Densities.

Pb is around 9 grams/cubic centimeter
Cu is around 8.1
WC is around 12
Au is around 17
Pt around 19
Os, Ir are 22ish. VERY DENSE STUFF
On the other end of the spectrum
Graphite is around 2.2
BeO is around 2
Mg is around 2
Al is around 2-3 depending on the alloy
glass is 2.2-3.3 depending on how its cooled and whats in it
Steel is 7-8 depending on the alloy
Stainless steels are 8-9
and I think Titanium alloys are around 4 grams/cc.

I think that should give you a good relative idea of how materials stack up to one another. You can really "feel" the difference if the density is about 3-4 grams/cc between samples (of course that depends on how big the sample is, so I'm referring to small palm sized samples).

Gold and Tungsten are both at around 19.3 g/cc, and platinum is near 21 g/cc. It's really remarkable when you start accumulating gold and you finally get to see just how dense it is. I've got a small vial that I've slowly been adding gold nuggest, gold coins, gold ingots, and gold bars to. The minimum purity in there is 22 kt. But with the vial now full, the mass of it is incredible. It's almost too dense to believe. It's a similar situation with tantalum and hafnium. You usually don't hear too much about those metals, but when you've got an element collection like I do you soon find out that they are quite dense. It's amazing how hefty these mid sized pellets are.

my collection is a petri dish is full of Pt 99.9%+ scrap from wiring this or that...now if I could just firgure out how to melt it, I would have a nice ring for myself. :P

your right though, most people think lead is super dense stuff. That is, until they buy an au/pt ring for that special someone. Especially mens rings where there is alot of mass. The thing is, most people never get a chance to fool around with Ta, W, or any quantity of Pt / Au or any of the other lower transition metals (unless your into the bling bling 1-inch thick gold chain, though most of the time its just copper with a gold plating hehe!).
