Neck turning's a whole additional process too obviously. Not something for the majority of reloaders I'm sure...
but essential for good concentricity IMHO, i am amazed how much variation i often find in neck thickness, even when using quality brass like lapua. most sizing dies will make the outside of the case neck concentric to the case but any uneven neck thickness will leave the inside of the neck out of alignment with the bore of the rifle. not good for accuracy
how much difference it makes to your own group sizes from your rifle is for each shooter to decide but i believe it helps reduce the number of unexplained fliers. some target shooters will set aside a case that produced a flier for rechecking, weighing or simply put it aside for fouling or sighting shots but as we know this simply may not apply to most shooters, rifles or hunting ammo
