Re: What tools do I need to use 308 brass in my 260 rem?
"I dont know how to tell If I have thick necks?"
The "new" cases look fine.
Few of us have a tubing micrometer so, to check for too thick, seat a bullet in a couple and read the neck thickness with a micrometer or dial caliper. If they are .297" or less you are ok. But prove it by "painting" the necks with a felt tip marker, chamber the dummies and extract them, then check to see of the marker is rubbed off completely around the neck. Anything less than a complete circule rub is okay to shoot, otherwise turn the necks until they are less than .297" in loaded diameter.
Don't worry about a snug or "lumpy" looking shoulders, that will correct on the first firing! Use normal loads to fire form your .260 brass.
