chillidogs please go to wikipedia or a reloading site and look up the cartidges and you will find some of what you have been told is NOT true. Just what some thing is currect. Not simple to explain the differences between cartidges and even the bullet used by like sized cartidges. .
I haven't seen anything that has been mentioned that is completely incorrect. Some things have been simplified a bit, but nothing that isn't right. Please enlighten us.
