As the name suggests, its for a round for a science fiction kind of thing. How can I get a rough estimate of a fictional round of roughly modern levels of technology? Really, I am here for just creative purposes. Most of what I know was from other hand loaders and other professionals.
Anyhow, the rounds I'm thinking of are rather crude, consisting of .323 caliber straight walled, untapered cartridges, headspaced entirely at the mouth. So of course, they would have to be very long for their diameter, proportional to the very powerful sharps rounds such as the .45-120 or .50-140. Though of course, overall smaller. The three rounds I'm thinking of are of course divided by the engagement ranges or size of game.
Though what I'm thinking long and hard about is the longest one. I'm thinking of a around that would fire a 160 or so grain spitzer bullet at 2500 feet per second for 2200 foot pounds of energy. How long would the brass case have to be? I'd suspect pretty long, but not precisely how long.
