Richard doesn't neck turn for that particular barrel. That is correct. However, he is using Lapua 6br brass in a fully custom rifle
chambered for a non-tight neck but it is still very small tolerances I'm sure. In other words, he is using top notch equipment which means his brass probably had very close neck wall thickness right out of the box. Both my lots of 6br brass had less than .001" variance.
Now, this is one guy with one good group. Now lets look at how many of us buzz our necks compared to the few who don't. It is a high ratio.
Remember, consistency is the key to accuracy. I wouldn't let one isolated scenario lead me to believe that that is the way it should be done always. FWIW. [img]/ubbthreads/images/graemlins/wink.gif[/img]
