lol, thank you but my knowledge is pretty limited. i've spent a great deal of time surfing the net and reading the occasional book on cartridges or firearms, otherwise i lack any real education on either topic. its thanks to this forum i've had the chance to speak with some real authorities on both topics!
some very wise people on this forum, to learn you just need to take the time to read and ask questions of your own.
on a similar note if you like dangerous game cartridges i recommend a book i picked up in South Africa. its called "African Dangerous Game Cartridges" by Pierre van der Walt. i dont know where/if you can find it in the USA but its a great read on the topic and covers some fairly rare cartridges. i especially find Mr. Walt's theory on what makes for the ideal expanding bullet very interesting!
