The case capacity results will be informative. Most of my 458 Winchester brass are WW. I bought in bulk many years ago, following a dry spell of seasonal production runs.
I stated using Hornady brass out of necessity for the 375 & 416 Ruger cartridges. All I can say is, I have not shat-canned the cartridges because of terrible brass. No it is not Laupa, but seems workable.
The Hornady brass is all I have for the 458 Lott. It is not a pretty or perfect as a couple of other brands, but plenty useable for me. Until Michael458 helped me out, I definitely ran some higher pressures than intended or spec'd for the 458 Lott.
The bonded .458 DGX seems to be a very usable bullet. Yep, bless their hearts, Finally!!
