I like PPU brass. It has come a long way in the last twenty years. The first Privi brass I picked up was a pain. It was in 7x57 and the standard #2 Lee Shell Head Holder was to small. The root diameter of the rim was over max. One time use only.
Never had an issue with rimmed cartridges they offered in Canada at all.
I find all of the cases which were once military are made to milspecs, hence the thicker sidewalls. Surprising, that extra material doesn't come cheap. It sizes well and will go around 4-5 reloads before needing to be annealed again.
