Re: what makes lapua brass so good??
It is good because one case is about as close to being identical to the next one as you can find. Meaning your carefully measured (weighed, thrown, whatever) powder charges will have the same space to combust in each time. And your bullets will have equal neck tension to overcome each shot.
It all has to be in their manufacturing process and quality controls.
That said, it can still be improved with a little work if the gun, shooter, and purpose is up to it.
