Most of us are pretty independant, that being we are reloaders. I've collected enough components that I don't worry about running out in my lifetime. I've a 308MX and its my favorite rifle by quite a bit. I'm set with nearly innumerable bullets and 500 cases. I'm not worried. People like youself have been saying this forever since well before 2007 when I got my gun. Hornady developed the Leverevolution line not all at the same time, but inventing a new one when another older one has proven successful. I'm sure some more popular than others.
