The Redding bushing die I was experimenting with didn't size the whole neck like the Lee does. I did not like that. I also like the fact that with the Lee no lube is necessary.

Mine all allow me to size the entire neck if I want to which most omly get the top 2/3 sized.

90% of my sizing dies are FL bushing dies, set for a .001" to .002" shoulder bump. Some of them appear to not completely size the entire length of the neck, maybe 80%. But, the ammo chambers, shoots great, and ejects, so I don't worry about that 20%.

Doesn't happen on all. I find it odd, as well.

Picture it...you run your case into a die that forces the case to conform to an exterior profile. It comes out of the die shaped in perfect conformity on the exterior. If the case neck is not perfectly uniform in thickness, what has happened to the concentricity of the interior dimension of the case neck?

It still is not perfect, but better. Some brass flowed outward causing a longer case, and an out of square case mouth.
Yes, no?

What I am trying to point out is that when case neck thickness is not perfectly uniform all the way around (let's say it measures 0.016" thick on one side of the neck and 0.0175" on the opposite side of the case neck) but the outside dimensions are all perfect, then there is no way that the inside of the case neck is concentric with the rest of the case...which means that when the round is chambered the bullet is offset from the center of the bore to some extent.

I can't agree or disagree with that. We might be having to dive into measuring bullets also. Getting into ten thousandths is not something I have the ability to measure, or have noticed any effects from that possible off set.
Interesting discussion nonetheless.

For my money, I'd rather have the inside dimension of the case neck concentric with the case body than the outside, were I forced to choose. Clearance in the chamber can negate the effects of non-concentricity of the outside dimension of the case neck when the cartridge is headspaced the way we both know it should be.

So standard dies, not bushing for you?

I've been working with collet dies the last couple of years, but that choice was made based on some demonstrations I saw on youtube a while back.
These other things hadn't occurred to me until I considered one of your comments above, but then it hit me.
I'm thinking that collet dies stand a better chance of keeping the inside of the case neck concentric when neck thickness varies, but that's just based on intuition.
One clear advantage to the collet system is that you don't size the outside diameter of the case neck to perfection and then drag an expander through it. You squeeze the neck down to force the inside diameter to conform to the central axis of the case body and the neck's outside diameter just ends up wherever it ends up. It all happens in one event, not two.

Anyone know the thickness for hornady or other makers of brass? My alpha is measuring .015 rather consistently and I am curious how this compare to other producers.
