For those of you that use a NECO concentricity gauge or similar style...

IMO, it's the best one out there.

I did check that one out and agree it looks quite nice. It is to rich for me right now though. Thanks for mentioning.

The only way to fix runout is fireforming/refireforming. A die cannot do it.

The primary cause of runout is thickness variance of a case.
The initiator of runout is sizing, and misaligned sizing can also directly cause runout of course.
A minor contributor is misaligned seating.
To make straight ammo you need to address the actual source/cause of loaded runout.
Culling cases by thickness variance, neck turning, minimal sizing and seating with inline dies, etc.

Once you've made crooked ammo, you can adjust only eccentricity of it, possibly with a cost of increasing runout further(neck bending). But concentric ammo that is crooked won't chamber and fire the same as straight ammo. It's not the same thing.
You can make it straighter by firing it in your chamber, and then try again to size & load it straight as measured on a runout gage.
Work out the bugs a couple times & you'll get real good at it across the board.

The NECO is an excellent gage if you're set on it. I just prefer Sinclair, and I also prefer their neck turning system, and neck thickness gages, yadda, yadda. I spend a bunch there I guess...
Im getting 1000 pc of winchester .308 brass for a LR308. What I usually do with a new lot is full length size, flash hole deburr sort neck thickness with Redding neck thickness gage, keep the ones .0015 or less , neck turn 80% of the neck and hard into the shoulder, uniform p.p.,then weigh sort.
These are to be partial full sized and annealed every time. THIS BEING A GAS RIFLE, in your opinion would I be better off spending time on other things or am I on the right track?

Whoa on the hard turn fella. Don't go crazy there.
I would invest in a neck mic rather than the Redding neck indicator, and cull brass not only on thickness, but thickness variance.
Drop case weight sorting(meaningless).

Sounds like you got a good plan to begin though.

I meant to say variance. (I keep those whose neck varies .0015 , supposedly the case is the same thickness variance all the way down).
I use a ball micrometer also. It verifies my dial indicator reading.
