My first questions would be what is the underlying cause of the TIR you're currently getting? What setup are you currently using that gives the occasional case with excessive runout? How much TIR do you consider excessive? I personally wouldn't be concerned about TIR of less than ~.003" (or greater), especially if you are running a no-turn neck chamber. This is likely because with the long tight freebores we typically use in F-TR, the side clearance of a no-turn neck chamber generally means the bullet will center itself with respect to the bore axis when you chamber a round and close the bolt.
Certainly an improperly set up sizing die, or one that has a defect, can be the cause of excessive runout. However, uneven case wall thickness will also cause runout over time as the cases "banana" more each time they are re-sized. In the olden days, shooters sometimes placed a notch or other mark on the base of the "banana'd" case so they could orient the mark/loaded round in the chamber with the same orientation in relation to the "banana" curve every time. It worked fairly well. In general, no re-sizing die on the planet will fix runout caused by uneven case wall thickness. Neco (the outfit that sells QuickLoad) sells a case wall thickness/concentricity gauge:

It's pricey, but so are custom resizing dies, especially if your current dies themselves aren't actually the cause of the TIR. Even the very best brands of brass currently available can have the odd case with non-uniform wall thickness. Just a thought.
I had a 7-08AI bushing resize die made off brass I sent them several months ago. The Dies I received are flawless. Perfect in every way.Has anyone had Whidden make a sizing Die
in the last 2-5 months? Reason being, I'm also needing another custom made.
(stupid wild cat) I had one done this past spring---3 times. Dimensionally way wrong and gouging, not scratching brass. I would try them again if it's been straightened out.
Good to know. I may try againI had a 7-08AI bushing resize die made off brass I sent them several months ago. The Dies I received are flawless. Perfect in every way.

Just to clarify, 3 pieces 3x fired plus my Reamer print sentMy experience with a Whidden custom bushing die is nothing short of phenomenal, although I've heard of some complaints as evidenced right here. I sent them my reamer print and 3 pieces of 4x fired brass that had been neck sized only. After 4 firings, this brass was really tight in my chamber. Whidden used that brass to make me a bushing die than minimally sizes my cases all the way down, including diameter reduction at .200 line. I couldn't ask any more of this die. Perfect sizing and no clickers.
I know guys send them the reamer print only and they will make the sizing die from that, but they say right on their website that is not the ideal solution. They would rather have the fired brass to work from.

That's hard to do. Every firing and sizing cycle makes the brass harder. Therefore the tension and amount of bump changes. You might get close if you have a good annealer and annual every time. MattIs that a Lee collet die?
If so, I'm trying to avoid bumping shoulders in one step, and sizing the neck in another. I could pretty much do that now with my current whidden FL die, and mandrel it back up (or use pin gauges).
I shoot a lot, and I'm also very lazy.
I'm really looking for a 1-step sizing process that gives me .001 tension, .002 bump, zero run out, and hits those numbers every time. That's not asking too much is it?![]()

Its not side to side play its the squareness of how it sits there. It needs to be able to float but it can float less if the die is straight.I believe you. I just don't understand..I guess the whiddens don't allow as much side-to-side play with the bushing?
Here's where I'm hung up....If the die is bored out to .5" in the bushing area (hypothetical numbers), and the bushings are .495 OD, then how does the die affect neck concentricity.
Whidden or harrels for 30br?
