Rotting ammunition
Encourages unloaded weaponry when not in use, and has a “use-by” date once open | |
These bullets are packaged in a way that prevents their
contact with open air. Upon breaking the seal to get
them
out, a chemical barrier, perhaps hydrophilic, starts to
change state inside the shell, eventually exposing the
gunpowder
and whatever chemical encased therein to a quick
spoiling
reaction that prevents the ammunition from
firing off
after a reasonable time period—say 12 hours perhaps.
Keeping such rotten ammunition from ruining the barrel
like a spoiled battery is the tough part.

Limited-life cartridge primers [xaviergisz, May 24 2018]

I don't know about rotting, but having it not fire
after a few hours might be something that would
prevent accidental shootings. |
|
| |
Heck, have it only last for a few minutes before
"expiring". Pull it out of it's wrapper, load it and
shoot it. If one's left in the weapon accidentally,
it's inert after
14 minutes or so.

I think you'd simply have the primer, the only part
of the explosive part of the cartridge exposed to
air, change. |
|
| |
Ok, here you go. There's a solid piece of something
that quickly deteriorates and turns soft after a few
minutes of exposure to air between the primer and
the hammer. It's hard enough to transfer the
impact of the hammer to the primer for a few
minutes, then it degrades and gets soft so when
the hammer hits it it simply absorbes the blow of
the hammer without transferring any impact to the
primer. |
|
| |
You'd peel a little metal tab off the rear of the
cartridge to arm it and expose it to the air to start
the degrading/di-fusing process. The metal being
necessary to block the hammer if the tab was left
on. |
|
| |
There's already a bit of metal between the primer and the hammer. A
spent round has a neat little dent in it where the firing pin hit it. Your
proposed tab needs to be strong enough to resist this impact, but
flexible enough to peel it off; sounds like a tall order to me. |
|
| |
Maybe a disc of material that expands as it absorbs moisture from the
air, gradually moving the whole cartridge slightly further down the
barrel, eventually reaching a point where it's too far away for the firing
pin to reach it? |
|
| |
Why would any gun owner buy this ? It's not useful in any way. |
|
| |
Throughout your history the emphasis has almost invariably been on improving the shelf life of products. For example, a well-known brand of fast-food hamburger can be stored at slightly above body temperature for years with no degradation of taste, texture or nutritional value. Admittedly it didn't have any of them to begin with, but the principle remains valid. |
|
| |
Well, it seems to me like a great way to issue ammo to armed police.
Ideally you want them to just go in there and get the job done quickly,
and with minimal risk of their ammo being useful to any criminals who
might get their hands on it. If things go sour and the operation takes
longer than anticipated, the guys could probably use a break anyway,
so send in a second squad with fresh ammo to take over. |
|
| |
I was reading how controlled the issuance of ammo
is in the military, and trying
to think of ways to bring the same effect to the
general public. |
|
| |
You wouldn't want the transition to be a slow one, as
that could be
unsafe for the owner and/or spoil the weapon. |
|
| |
I think some reasonable number of hours, say, for a
hunting period,
extended police shift, or somesuch would be a good
timeframe. |
|
| |
//Your proposed tab needs to be strong enough to resist this

|

Easy, picture a dime with a piece of tape over it. No need
for flexibility on the blocking piece, just the tape holding it
in place. |
|
| |
I wouldn't want the technology chosen to be of a
type that would be easily defeatable, and I suspect
the only way to get it into the marketplace would be
to mandate it as a requirement. |
|
| |
Could also replace the tape with a snap on / snap off cap
that was big enough that it wouldn't fit into the clip or
chamber until it was removed. |
|
| |
Idea number two: Peel off the tape, the primer is exposed
but there's springs that pulls a blocker into place. This
spring is coated and infused with a solid material that
evaporates or softens when exposed to air. After a few
minutes the spring, no longer held in place by the material
pushes or pulls the blocker in front of the primer. |
|
| |
I'm still leaning towards something that spoils the
gunpowder. |
|
| |
Problem is that powder in the cartridge is sealed up air
tight. Unless you're using something else to start the
degrading process no air is going to get in there. |
|
| |
Just make the seal between the shell and the casing degrade on contact with air and humidity will soon spoil the powder. |
|
| |
Looks like it might be time to start stocking up... |
|
| |
That’s what I’ve essentially proposed. A degrading
chemically-timed seal that once degrades opens a
fast path to powder spoilage, which would be
encouraged by some chemical means. |
|
| |
Packing them in tobacco tins full of bacon grease will cure that right up. |
|
| |
There weren't many things I got to learn from my grandpa... but that was one of them. |
|
| |
...an other thing was that, if you get your hogs hooked on canned corn they will uproot any stumps within their enclosure if you've auger-ed holes beneath the roots and poured canned corn down them before letting them into their new home.
Tilled and fertilized... for the cost of a couple of cans of corn. |
|
| |
Oh!... and that you can train a turkey to attack the legs of anybody who doesn't know his name through the steps leading up to your house if you make that its pen. |

The other Grandpappy taught me the correct Quebec pronunciation over the France pronunciation of the phrase 'baby duck'. Still remember arguing with him about it as a three-year-old to this day. |
|
| |
Aren't grandpa's just totally friggin awesome? |
|
| |
Anyone that gets access to imprinting state will always be
frigging awesome. |
