RE: Most Important Reloading Measure
The old timer might be right, but I believe the difference in acuracy you get by neck turning (outside?) is of more interest to a bench-rest shooter than to someone using a factory-built sporting rifle for big game hunting. I am pretty happy with 1.25 MOA for five shots from a hunting rifle, although I have several that do somewhat better than this. Neck turning is a real pain! I suppose it does add to the reloading experience, however.
