[QUOTE="nevada75, post: 1741014, member: 75285"] I had the same problem forming 30-30AI using PPU brass using a mid-level charge. After lots of measurements and weighing individual cases I found PPU is heavy, thick case walls, etc reducing internal case capacity thus resulting in higher pressure. Sort like loading military surplus brass. I backed off to a lite starting load with lightweight bullets and the issue went away. Keep in mind the pressure issue when doing load development with your fireformed brass. I couldn't get anywhere near max published loads before pressure signs and higher velocity occured. [/QUOTE]
