6.5x47 lapua die question

[Idaho Trecker]

Probably a long shot on here but it's the only forum I participate on. I'm going to be buying a redding fl bushing die for this project. I'll start off with I'm an odd one that loves 270 cal. That's neither here nor there but I'll be designing my own chamber reamer to simply neck this up to 270 cal and throat how I want it.
My question:
Has anyone used this specific die on a 6.5x47? I'm wanting to know the OD of your sized case at the 0.200" line and at the shoulder. This will help me with my reamer design to make sure I'll be sizing the brass how I want based off of these measurements.
I'll likely be using peterson brass but open to lapua or alpha. If anyone has average neck wall thickness of any of those brands of brass I'd appreciate that information as well.

I don't have a Redding bushing die, but I do have some Lapua and Peterson brass I shoot in the 6.5x47L I can measure for you tomorrow when I get a minute.

Thank you!

What brass is more important…
My Lapua brass is barely moving, however my dies are not Redding but Forster BR dies.
My brass is also put through a roll die to keep the .200" line at the unfired dimensions.
Depends what end you are wanting.

Cheers.

Turns out my Peterson has all been neck turned to 0.0125". The two different lots of Lapua are both very close to 0.013". Give or take half a thou. I also use Forster BR dies and a bushing shoulder bump die with a .287 bushing. I also have a Redding body die if that would do you any good for measurements.

Thanks for the response @ImperfectLiberty . Can you tell me the diameter of your peterson brass after being sized at the .200" line and at the shoulder?

Let me tell you the CORRECT way to design/alter a reamer.
First off, forget sizing die dimensions. Period.
Choose your brass first, measure everything, look at CIP chamber dimensions, NOT SAAMI, they didn't approve the cartridge until AFTER it was submitted to CIP by Lapua/Nammo.
Base everything off these numbers, if you want a longer throat, measure it, don't guess. Then design the reamer to suit. My reamer is CIP with added throat length, so was my 6.5-284Norma, they are essentially 'match' reamers but on minimum spec dimensions.
I could tell you what my reamer print is for F-class, but I would be wasting my time. You have not yet grasped what is needed.
Fired brass size has zero influence on reamer size, nor does the sizer die dimension…
Contact Manson or JGS before you proceed any further.

Cheers.
