I've only tried it in 7mm Rem. Magnum. Worked as well as anything else, but was very heavy brass, 14% heavier than Winchester and with a reduced internal capacity. Max. loads worked up in Winchester brass require a slight powder reduction with PPU brass to get equal muzzle velocity.
That’s really interesting. I use PPU brass in my 7x57 and find it comparable in weight (within 4 to 5 gr.) to Winchester, considerably less than Remington and way way less than Federal. Would be interesting to hear head to head weight results in other cartridges. Perhaps they have different standards with different cartridges. Nonetheless, I’ve found PPU excellent in the 7x57. Every bit as good as any of the other three mentioned brands.
