I've reloaded many thousands of rounds in various calibers of semi-auto, and never had a problem caused by brass that was too long.
That looks like it'd be better than the Lee tool that I have, the one in the bottom right corner of the page in your link.To Chamfer use a universal tool like this for both the inside and outside:

FC = Federal Cartridge.
It doesn't matter if you're using the min charge. If the bullet sets back far enough the pressures will be extremely high
