I posted earlier about a smith to build a 6 Super LR. A good friend of mine said I should take a good look at the 6 CM. I have done searches for this but don't get much info back. From what I gather Hornady is the only die maker? The brass is necked down 6.5CM brass, can it be made from other brass? I hear you can make it from 243 brass also with a special die, not sure. Is there actual load data in manuels for this round?
