Fired brass looks great as far as concentricity, at least the 4 or 5 I tried. Ordered an RCBS neck die today.

Yep, figured that.
Take a couple those 4 or 5 now fireformed brass and size them in your FL die without the expander stem and check what the runout is afterwards. Then put the stem back in and push the case up over it, check runout again.

My question is that I have 250 re-sized brass that I am sure most are going to be out of spec as far as being 3 thousands and under run-out. Is there a die that I can use to straighten them out?
And the source is inconsistent neck wall thickness that contributes to inconsistent case neck runout.... And for me a LCD solves most of that runout if not all, within .0005 to .001. AND that little bit left will not effect neck tension. TIR shows that. Do you own a LCD ?

Recently got a like new 257 Weatherby Mag Vangaurd in 257WM. Unable to source brass at a reasonable price I decided to make it out of once fired 264 Win Mag brass. Seemed an easy step as I annealed and ran the 264 through the 257 RCBS resizing die and brass looked great. I had some marginal success with a full charge of H4831 and 80gr Barnes ttsx's but was getting flyers in my groups. I suspected that it might have something to do with concentricity so I barrowed a gauge and checked the 20 rounds I had loaded. Seems the best neck was right at 3 thousands out and worst was 10 to 12.
I will admit to being a little lazy on resizing and I am sure that has cost me as I did not lube inside of neck on every brass. I did on some and I always spray 1 shot towards inside of necks when I lube.

Are you trying to tell us the neck walls of his brass are so bad that they produce 10 to 12 thousandths runout?
I know the results l get, and to honest l could care less what you don’t get. Bitch, ain’t that rich. What’s the difference if l show you my dies. You still don’t agree that it takes care of runout, REGARDLESS, if it wall thickness. Do you anneal before you use the die ? Probably not.

I say it avoids runout being introduced in the sizing operation on fired brass that comes out of a chamber pretty straight. I've used them for many years.
If you could show a pic of yours, with an irrefutable personalized note to solidify their provenance, it would at least show you have one even if you really don't understand it.
I don’t understand…. Hmmm. That’s a good one. Any body can use a concentricity tool to indicate a neck, W…. T….. H….. does someone have to understand to know how to read a dial indicator?? LMFAO. You guys are really to much, you really are. Get a LIFE!
If anybody doesn’t understand how a collet sizes more evenly and consistently maybe, just maybe you aren’t as smart as you lead people to believe you are. It’s a very simple concept with a very simple design. AND to top it off, you have nothing better to do than over complicate things. Y’all come back now ya hear !!!
