>>6061727I know this is going to probably sound silly, but you want to use it later for general ballistics OR is this some pointlessly veiled and sneaked attempt to get guns, rather than state it outright you are researching guns? Because it does make a difference - not in the research itself, but its application. So if the goals is getting guns, just get those. And if the goal is to get ballistics as such, that's fine, too.
Also, a friendly reminder to everyone that this is a silly kitchen sink fantasy game. Nobody is going to tell you to fuck off if you pull a portable gatling gun made of a diplodocus, bamboo, linen and pebbles. In fact, that's always far more interesting than the standard version.
