At Profire we used once fired winchester brass that was cut off like you do blackout with a chop saw, resized in a 338 hoosier die, trimmed to final length on a hand trimmer (with drill attachment) than loaded accordingly. Its very time consuming but we did not have much of a problem up-sizing the neck area in the standard form die as long as it was well lubed inside and out. Fired Hornady brass works in some guns, fired 338win works in some too.
The main problem is brass thickness hence new brass does not work in most guns because the chambers are too tight.
What is a 338 Hoosier die? Also, what is "fired 338win"? Did you mean 338 Federal?
Are you saying you shortened and necked up 308 Win brass and didn't have to ream or turn the necks?
