[quote=@Romero] Uranium is used to creates nuclear fission, this controlled nuclear fission energy is used as the substitute for the gunpowder giving the cartridge a huge amount of energy, far more than it would normally gain from igniting gunpowder, and so is fired at a far higher velocity. They're not nukes for a start. And to put it lightly, they're not beyond our technology, this little reactor isn't going to be able to power a city or anything, it will just be able to give the power for the firing of the rifle. So all you need is a source of radiation, in this case uranium which is handily abundant in my land, and some basic control rods to stop the chain reaction. The first nuclear fission reactor was built in 1942 I'm pretty sure, but it could have been built earlier fairly easily. All that happened was they then spent all their time and money looking at the bomb capabilities. The obvious risk of holding a small radiation producing stick of uranium is the inevitable radiation poisoning, but the sad truth is my nation nearly all already have it after the Fall. Why I want them is because A) It looks Hella nice and B) Granted you may have to stretch the imagination a bit, but not hugely and I like the idea of it! I could already write pages and pages about this nation and their interactions with their neighbours! And thanks [@ClocktowerEchos], but my nation is all burnt up and poisoned with radiation, it's either radiation powered guns or deadly sightseeing � [/quote] I am no radiation expert or science expert, but I can easily call out BS on this. I know for a fact that uranium needs more power than something a gun or even a heavy ass back pack can produce in order to use as substitute for gunpowder. I'm not even sure if you could get it to work without violently exploding and killing your own guys accuming it would work. Also, may I ask how the hell did your [i]entire[/i] nation get radiation fallout? If that's the case, the entire fucking [i]world[/i] would be having some trace of fallout with wind currents and stuff. In short, where the hell is all of this stuff coming from? How the hell does a former colony have such advanced nuclear tech that they can make guns out of it (that wouldn't work). The rest of the world is most likely just getting started with nuclear reactors and you're chilling over there with uranium guns and nuclear fallout which some how doesn't affect anyone else.
