I'm getting a 260AI project going and had a question about fire forming the brass using the cream of wheat method and a false shoulder. Since I need to expand the necks for the false shoulder anyway would there be any advantage to using Lapua 308 Palma brass. The neck is already expanded, the small primer makes a stronger case head, and if the necks come out thicker I could turn them down to fit the chamber and not be so sloppy. Or should I just use 260 Lapua brass and go that route? Thoughts?
