I have a lot of Lee equipment and sometimes defend Lee on this site.
I just bought a Carcano and ordered dies for it. I normally buy Lee and I bought their dies. It turns out that the shell holder that they send is way off. You press in the case and try to get it out, and the rim is ripped off the case. This has been reported by others for quite a while. If Lee knows about this, why don't they raise the price of their dies a bit and buy the RCBS shell holders, or create a new shell holder that works?

Mike - watch out for those Carcanos! They say that when you shoot them, the bolts will come straight back and go through your skull. They also say they explode if you look at them wrong, and.....
Sorry. I just had to do that, before someone else comes along and spreads the Internet gospel.
By the way, is it a 6.5mm or a 7.35mm?
I did note that Lee lists Shellholder #2 for the Carcano, which is the same one used for the .308/.30-06/Mauser cartridges. In COTW, the Carcano shows a rim of .448 while the others are all based on a .473 casehead. Looking for others closer to the Carcano, I see that the #12 (for the 7.62x39mm) is for a casehead of .440. I wonder if that could be made to work better for you. Of course, Lee will be the ones with the answers - but you can always ask that question to them.
Good luck!
