I concur with your thoughts about using 338-06 data as starting loads.
The Nosler 280AI case length is 2.525 and neck length is .345". After my got her 280AI I had 30-280AI build and after I got few cases fire formed I neck up some to 338.
I've got a set of dies for a 338-270HGT and the body length is 2.090" has 40 degree shoulders and neck length is .370" and case length is 2.490" long. there is article in Wildcat Cartridges Vol II page 461 about this wildcat and it's about the only written information about this case. It's pretty close to a 338x280AI. they have data for a 200gr Speer@ 2900fps plus and 250gr Sierra mid 2600fps.
I used 280 cases to fire form reason for that 270 case to the shoulders is 1.948" and the 280 length to shoulders was 1.999". I have the dies in storage not sure if I have any cases and if your interested you can have reamer made from the dies and I'll send along the loading data and it be a good start on something no one else has. You have to talk to reamer guy might be able to use 280AI reamer any way if your interested PM me and you can have them.
