More from Karno
Hit a local gun show today. I wasn't four feet past the door when I sold the .22 rifle I had with me. As was said at the show: "The white guys are afraid Hillary will get in, and the black guys are afraid Trump will get in - so EVERYBODY is buying guns!".
Picked up ammo, mainly. The box in back is tungsten (Danish for "heavy stone") 10-gauge shells. Tungsten is heavier (?) than lead, but a lot harder. Good stuff for blowing thru soft barricades like car doors.
The other stuff is assorted 12-gauge, a "universal" holster, some 44 special, saboted bullets for my .50 Hawken, and a couple of tracer rounds in 50 and 308. Loading a tracer a couple cartridges away from the bottom of yer magazine gives you visual warning that you're about to run out of ammo, and should get a fresh mag ready. Yes, this is the sort of stuff I think about.
Even so, I left the show with more money than when I entered. A strange feeling.....

No. Pure Bismuth is almost exactly as dense as lead. I don't see any way to make a Bismuth alloy denser than Tungsten.
Tungsten is twice as dense as lead, almost exactly matching Gold.
Bismuth is popular because it is non toxic, dense, and softer than Tungsten. Probably cheaper, but not sure.

I doubt they make those rounds in anything other than the caliber the A-10 Warthog uses.
Those things are anti-tank armor, the outer layer actually goes plastic, 'lubricating' the round as it pushes through the defences. It's hard to justify needing THAT much penetration outside the battlefield; too much risk of hitting the innocent behind the wall behind the body-armor-wearing suspect you shot.

'Plastic' is another way of saying 'semi-molten.' When the material is warm enough to be deformed and flow, but it not actually liquid, that is the 'plastic state.'
You also see that with 'stir friction welding,' where the two panels are rubbed by the 'welding head' until they achieve a 'plastic state' and are 'blended' into a single seamless piece. NASA uses that a lot on space capsules, since the aluminum skin would warp under the heat of traditional thermal welding.

I never thought about it that closely. Uranium is cheap (essentially worthless with current design power reactors), dense, and melts easily. Tungsten isn't going to melt much. Other super dense elements also have high melting points, and are rare.
Personally I think that they should save depleted Uranium for use in a proper reactor. It is possible to design a safe reactor, once you give up on collecting Plutonium. Off Topic.

Every bit of research i've done on this including statements from some magazine manufacturers has said that yes, what wears out their magazine springs is repeated loading and unloading, as opposed to keeping them loaded.
hickok45 on youtube also did a good vid on the subject.
While keeping them loaded will probably wear them out a tiny big faster than keeping them unloaded, the difference from what i can tell is pretty small.

I once kept a brand-new PMAG with a brand new Wolff spring loaded to capacity for a year and a half or so, next to a stack of some other brand new unburdened Wolff springs. The loaded magazine spring was about half an inch shorter than the virgin springs upon disassembly, but that's still longer than the used mags I had. So there's a little fatigue from being stored fully loaded, but in that case it didn't seem to be enough to actually make a difference.
that's a nice feeling. I went to my first real gun show after moving from california to texas (California gun shows are a joke. They're basically stun gun and cheap chinese made junk knife shows) and figured i needed a texas gun, i was set on a colt 6920, had a cz527 .223 with a little for sale flag on it. was really afraid it wouldn't sell otherwise i couldn't get the colt, there was only one in the whole building amazingly among the probably half a million guns there. I didn't even make it through the line to get your hand stamped before i had 2 offers on it, 5 steps after that it was sold.
A sabot round is a smaller caliber bullet wrapped in a covering that matches the bore of the gun you're firing it from. When you fire it, the sabot drops away from the bullet after they leave the barrel. The ones you see in the photo are .45 cal bullets wrapped in a 50 cal sabot - for hunting, basically.
The military uses Tungsten inserts and nylon jackets today. So I hear. All of the power goes into the insert, and the outer bit would seal good, while reducing wear on the barrel. Some experimental rounds - eg a 223 bullet in a 50 cal case will work, but wear the barrel out quickly.
Note - I know that Karno knows this stuff. This is for other readers.

Exactly, it tall and goateed one.
'Sabot' is french for 'shoe' (specifically the wooden clog), which is where the term comes into the ballistic sense. The Sabot is the 'shoe' that lets the round fit into the barrel.
Mythbusters also made Styrofoam sabots to launch the poultry from the infamous Chicken Gun.
Even 'wadding' could be considered a form of sabot for muskets, although that might me more like a sock than a shoe.

Um, did I get derailed with my analogy there? I'm not sure.

Tungsten is very very hard and heavy. For this reason it tends to make fine tips for AP ammunition. But at the same time it's very brittle. It's brittleness is compatible to a porcelain plate. Tho, that matters little when it's flying into a softer surface at very high speed. It might shatter into dust. But it's a compact wad of dust that smashes it's way through softer metals. It's also has a very high melting temperature. It's used for the electrodes of welding equipment because of this.
That is some cute loot. You did well! I had forgotten you had a 10-guage.
Yahoo! New England gun shows start up again near the end of September! Maybe I'll find the 8-ga. kiln gun I've been looking for...
