Waiting on my new barrel to get here from mystic and I am starting to accumulate the components, I usually used the more common brands but would lime to make the most of my lapua brass and get the most accuracy I can from the new barrel. Like the idea of bushing dies to maintain concentricity

Mine should be done by the end of april. Im pretty pumped to try it out.
I ordered the Redding type s match die set with a 0.289 bushing.

Whidden Gunworks. Stopped using Redding and haven't looked back. Excellent quality, great pricing. Really like the option of a full size die with a bushing. Comes with a micrometer seater die. Around $200. Can get them direct or from Bighorn Sales. Gary is a stocking dealer.
The bushing size has nothing to do with a fired case. You seat a bullet in your sized brass, and measure the neck OD, then subtract .002" for the bushing size.
It looks like 7mmremmagnum made a good guess and picked the middle of the road bushing. If he is neck turning then he did not guess and knew what thickness he would turn the necks and ordered the correct bushing size. (ahead of time) 
All Forster Precision Plus Bushing Bump Neck Sizer Dies come with three bushings to cover neck thickness variations between case brands and desired neck tension. The .287 bushing would be a good choice if you do not plan to turn the case necks and use the expander that comes with the Redding type S dies. The .289 bushing that 7mmremmagnum ordered falls in the middle and is a good choice when just ordering one bushing for starters and .012 to .013 neck thickness.

I run Redding full length Type S Bushing for my 6.5x47 with a .287 bushing and the carbide expander option. I run all Lapua brass. I've just started neck turning, so we'll see. I have the Redding micrometer seater as well, and have runout that measures under .001 most times.
If you look at the Whidden custom die web page they state that they get better concentricity with a standard full length NON-bushing dies.
My first choice would be a Forster full length die with the high mounted floating expander for less neck runout with a standard SAAMI chamber. If you ordered a tight neck chamber with your new barrel then a bushing die would be better. Anytime you reduce the neck diameter .005 or more using a bushing die it will induce neck runout. And this is why it is recommended to reduce the neck diameter in two steps when reducing the neck diameter .005 or more.
Forster will also hone the dies neck to your requested diameter making them a very good choice for a non-bushing die.

Simply put, you control the case neck thickness so you KNOW which bushing to use.
Outside neck turning is a must do with bushing dies and since you will turn to the SAME thickness and anneal, you can pick the bushing you want to use right now.
Give me a shout.... options to offer.

I find that I can't quite get the bushing guess/math right Jerry - I have had to seat a bullet to get my proper measurement to subtract .001 or .002 from.
Am I missing something?

Below is the math...
(Case neck thickness X 2) plus bullet diameter defines the diameter of the seated bullet.. now the fun begins... the guess is how much spring back the case necks will give you vs the neck tension you need/want.
For precision work, rule of thumb is 1 to 2 thou of neck tension.. anymore and you will likely introduce runout.
So seated diameter MINUS 2 to 3 thou is the typical place to start with bushing sizes.
Because there is no way to know what the actual spring back will be (varies due to alloy, actual thickness, and work hardening), you play with bushings in 1 thou increments until you get a warm fuzzy feeling... if you need a 4 thou smaller bushing then the seater diameter, me thinks you need to quickly move to...
Proper annealing to soften very springy brass.
Constant and proper outside neck turning WITH annealing will help to keep the necks consistent so the "bullet pull" you just tuned for stays consistent.
For hunting, a bit more neck tension will not be a bad thing as failure to function trumps a tenth or two at the target.
Enjoy...
