Sorry for no intro or request to join - this is my first post here. So hard to sit back and shut up when the "Swede" comes up.
Ben, I've used PPU ("peh, peh, oo" - our alphabet/their sound system) in an M38, a 94 Carbine and in an '09 Argentine with a A&B 6.5x55 barrel shooting only 160 grain (jacketed) bullets and it has been excellent brass. I got mine as loaded "surplus-looking" ammo and haven't kept track of the number of times I've loaded it. I load the Swed pretty mildly and counting firings just gets boring.
I had no idea you could just buy it as new brass.
I use mostly Norma for the 'Swede - simply exquisite brass.
I have some Remington as well and no complaints, but the Norma dimensions are more correct and consistent.
The PPU, in my experience, falls between my Remington and Norma in quality - Better (nicer) than the Remington but not quite as nice as the Norma.
I have 200 rounds of Ingram FMJs to shoot up or pull, which looks very nice too, but the flash holes are small and pull the decapping pins out of my LEE dies.
All but the Ingram was acquired 20 to 25 years ago, so quality may have changed, but I'd buy PPU brass again myself in a heartbeat.
By the way, I'm not sure how the new brass is headstamped, but mine uses the Cyrllic alphabet and looks like "nny." If you see it at a gun show or yard sale, grab it.
