I'm both surprised and very pleased to hear that the Hornady brass is holding up so well. Anything that comes remotely close to Lapua cases is wonderful!

Lapua/AA headstamp
Nosler (this is Norma brass)
Hornady
New lot PPU (120gr MPT brass)
Old PPU (123gr SP)
I have a lot of the Hornady, but have focused mainly on loading Lapua brass. The Lapua and Norma/Nosler come chamfered already, very clean, very high quality. No need to size, just load and blast.NRA Basic, Pistol, Rifle, Shotgun, RSO

The Lapua head stapmed brass also has a slightly larger flash hole compared to the AA head stamped brass. The flash holes in the Lapua brass still appear smaller than the Hornady though. The smaller flash hole was a problem for some who used Lee reloading dies.

I guess I'll have buy a bunch more Lapua brass until I get some that prove me wrong.
I'll see if I can get some measurements of the flash holes
