I find this thread rather interesting for some weird reason.
Still I think most likely a compressed dart of some type with some poison on it's tip would be the easiest to make. . .
I'm only speculating here but. . .
But after careful thought, one really could build a frozen round. Maybe not of ICE if you wanted it to have good weight or sectional density for
flight. But there are other materials one could use.
Most likely you wouldn't use a normal propellant, but a gas that would expand rapidly at a lower temperature or something similar to a cyrogenic
liquid combined with a carefully calculated expanding heating charge of some type. Digging though my old books, LOX (liquid oxygen) for example
expands at a rate of 861 to 1 @ 68 deg F. (I'm not saying LOX is a viable material since it might ignite any oils in your gun. And the fact it's
highly reactive. But something with a high expansion ratio.) It would be a one shot affair however, and unless you can get your propellant to produce
gunpowers pressures forget about cycling the action on some assault rifle or machine gun. . . What you are trying to create is a controlled BLEVE
(boiling liquid expanding vapor explosion) and keeping the expanding gas fairly cold in the process.
As a side note: (I believe most .308 cartridges (closest match to a 7.62 x 51mm Nato) out there produce 50,000 to 67,000 psi at the chamber depending
on what you combine (cartridge, case, primer, , but then again you would have to match up the weight of your bullet to your charge. Bullets for that
caliber run anywhere from 55? grains (plasic saboted - no longer made? I'm thinking of the winchester accelerator ammo btw.) to 250 grains)
Most likey the if you are using ice the round would be in the subsonic catagory unless you took the time to wrap the round in a protein chain or
plasma (not the hot stuff folks but what's in your blood stream) or basically something that will melt off and blend with the target. Ideally you
would put it into a cartridge that would fit a normal gun, and go that way with it. And to be effective you would probabily want to keep it larger
caliber with a lowered barrel spin (rifling)
Something to remember is bullets are made though many methods, some fragmentation rounds are made by pressing powdered metal together. I seem to
remember some claims about some law enforcement officer shooting a pistol out of some guy's hand while he sat in a chair in the middle of some road .
. . and the round that was used was claimed to be one of these 'pressed' fragmentation rounds. To speculate a bit since I don't remember the
details, I think the round was used to prevent a ricochet?
Now that I've said all of that all I'm trying to get you to understand is it's all in how you put the materials together. Don't think at STP or
standard, temperature and pressure. . . (68 degs F and 14 psi / 1 ATM (- weight of atmospheric air btw)) when these bullets are put together but at a
perhapse much lower temperature and quite possible higher pressure. And the same could be said of the propellant.
Something also someone must remember that ideally you will have to store the round somewhere under certain conditions before deployment.
Now rather this is practical? Heh. . . who knows. We as people have built alot of strange things out there, and one only has to do a light search to
find that out. Still I find some of these things interesting to analyze.
