Case neck sorting tool necessary if turning necks?

[thefitter]

This is a related question to the "best case neck gauge" thread. If I'm turning my necks what would be the point of using a case neck sorting tool? The way I see it is that I need a ball mic to establish and log a set neck thickness to turn too. But I'm not sure why I would need to sort the brass by neck wall consistency if I'm going to turn it. What am I missing?

Thanks

They are actually two different types of tools.

The case neck sorting tool allows you to quickly sort through new brass some of which may have necks that are way off and you discard those for precision reloading. New brass that have big neck thickness difference cannot be fixed by neck turning and those are usually discarded for plinking. These tools typically used dial micrometers that allow you to measure down to only about half a thousands difference so not so accurate. They are easy to use and so allow you to sort through lots of new brass quickly because you can insert the case in and rotate the neck and quickly see the difference between the thickest and thinnest part.

The neck gauge discussed in the other board are ball micrometers and are used to accurately determine neck thickness, usually after you turn your neck. They are usually more precise micrometers and can measure neck thickness down to one ten thousands. People use them to assess the quality of the brass they shoot precision rifle with and to determine how well the neck turning tool is working. They don’t work as fast because you can only determine neck thickness is specific areas of the neck.

Different tools for different purpose even though they are related. You usually need both if you are into precision reloading.

i am not sure where you are headed with these questions...

if you have a std chamber, a cleanup cut of about 30/60% contact MAY improve accuracy//
if the brass gets too thin the neck will not/may not align well.
may require bushing dies for correct neck tension

if a custom neck turn chamber..then go for uniformity with 1 to 1.5 clearance for most applications...

If you are turning your necks and are using a ball mic you don't need a case neck sorting gauge. The ball mic measures the wall thickness, even if the ids vary. On the case neck sorting gauge if your ids vary so will your readings so really what is it reading (wall thichness variation plus the amount the id is over the others that fit the mandrel tight compared to the ones the case fits on loose). You could get by w/o the sorting gauge if you have a ball mic and are turning necks anyway.

Thanks. The only reason I'm looking into this is that I'm going to have to use Remington brass for the new build I'm working on. I guess I'm going to have to wait and see how inconsistent Remington brass is and whether or not I need to cull any cases that are way off. I have never worried about this with Lapua brass.

Glad to be of help. I feel your pain. I’ve gone both sides of this myself.

When I used Win brass, I did have to do some culling but it appears that the Lapua brass I am using now seems to be very consistent and thicker! If you want a tool to cull, I would recommend the Redding Case Neck Gauge, it is not too expensive and works well. It comes with 2 mandrels which allows you to do cases from .17 cal to .338 cal.

You probably don't remember the topics we would argue on, not really argue but definitely had different ideas on the subjects, this is really funny though
