So you look to lee and dillon for precision?
Yes I certainly do.

I came from the tool and die industry and have a hard time getting my head wrapped around how any die with a round hole and a floating bushing creates runout. I can certainly understand that some have better tolerances, sizes and finishes but I've not experienced the aforementioned and just don't understand how it's even possible. Been doing this for years and don't get it! The case floats in the shell holder, that can float in the ram(to some degree) and the bushing floats in the die. What have I been missing?
+/- tolerances..002 is a very small amount and I'm not saying the die causes it. But if you have runout what does cause it?

Question
How do you maintain consistent seating depth with a loose or not tighten down die?
All I keep thinking when I read these concentricity threads (besides "pass the Rolaids') is the immutable fact that the brass is the ever-changing variable in this rabbit hole. It gets "hot swaged" in the chamber, then (sometimes) annealed, then cold swaged in a die. And every time it changes. Besides that, it is seldom perfect from the beginning.
I guess I understand for winning BR shooters why this "matters", but the air is so rarified there, when you can "call" a misaligned non-concentric cartridge on the target and not the hundreds of other factors...wind, light, bug in the path...
Now don't get me wrong...I see the fun in these exercises, but at some point, usually early on, it just makes me want to shake my head and walk away.
Donning flame suit as we speak...
Seating depth is a whole different ballgame. Most use an inline die which has nothing to do with the press. Some shooters purposely wear out their sizing press so it has plenty of slack in the ram so the die does all the work. Jackie schmidt comes to mind here- his partner presses he loads his br rounds with rattle when he raises the ram. Dont do anything to influence the case going into the die. The die is the only thing that needs to be precise you dont want a press having any say so in how the die works in sizing.
obviously you don't have a rifle that shoots in the 1's and 2's. if you are not looking for another 0.10 reduction in group size all tbese advanced reloading tecniques are completely unnecessary. fun if you enjoy that kind of thing but you probably won't see much of a change on your target.
Ahh..
Wrong, I do in fact. I didn't say they were unnecessary...I simply said most people are not going to be able to shoot (or own guns that can't) tell the difference. I also think that much of this discussion is belly button inspection. (so apparently it ain''t that obvious. Don't make the assumption I don't have a gun that will shoot, and don't know how to shoot it.)
I guess maybe I should point out that the vast majority of the guys who talk about dies and concentricity (maybe not here but where I happen to have heard it a lot) are typified by the guy complaining to me that his dies were giving him .005 "runout". After some pointed questions I learned he was shooting a Model 43 Winchester in 22 Hornet with a 4x period Weaver. He really should have tossed that C-gauge in the bucket and bought bullets instead. (I just buttoned up the suit and donned my helmet.....)
so going to start reloading for my 6.5 cm and was going to buy a die set. i was sort of stuck with redding on some other calibers but i kind of have my choice now. i just want something i can buy that is already in stock rather than special order a custom die. i have experienced getting more runout than i like using my redding type s full length dies,,,,it always happens when the neck is sized down by the bushing.
how do the whiddens and wilsons OR ANY OTHER BRAND compare to the same type of redding die
i really like the one stroke, do everything aspect of the fl bushing die.
I think you have one too many zeros in each of your 7 examples.I just now went to my reloading room and pulled out 7 different loaded cartridges, from 3 different calibers, and got the following run out:
.0003
.00015
.00015
.0001
.0001
.0002
.00015
