[QUOTE="Mikecr, post: 2959586, member: 1521"] Any method or brands will work as well -while everything lines up in your favor. But odds seem better with inline seating. It isn't just low runout, but also consistent seating depths, as press flex/play is removed. I've yet to run into an issue with Wilson inline dies, or Wilson die blanks chambered with my finish reamers. If necks are normalized for friction, then seating force variance correlates with comparative neck tension (what matters). Once you've seated bullets to identify outliers, I don't see where you can do anything but separate them out. So instead of seating force (with bullets), I measure pre-seating force (with an instrumented mandrel die). Here, I can adjust neck tension to match them all, before seating actual bullets. Mandrel expansion is another contributor to low loaded runout, as the mandrel pushes most thickness variance outward, without a possibility of offsetting necks (like button expansion does). Then your bullets seat straight with well centered necks. [/QUOTE]
