There are two broad categories of firearms that would be chambered for cartridges that develop 10,000 joules or more. One is military firearms. It's quite common for military firearms to be over that limit. The second would be rifles designed for hunting large game animals such as African game like elephants and rhinoceroses, animals of that size. It will involve the use of firearms that are chambered for calibres around 10,000 joules. They are not all over. There are calibres that are recognized as being elephant gun cartridges, if I can use a less precise term, some of which are over 10,000 joules and some under 10,000 joules. Where you see that level of energy in a hunting application, it is for large African game in general.
