[QUOTE="RockZ, post: 338787, member: 5750"] US869 is a great powder for an overbore cartridge like the 7ultra mag and would my first choice. It fills the case well and also doesn't have a problem with bridging within the case that could cause extreme pressure variations. Which sometmes can happen with extruded powder. Start with a mid load and work up . It is also pretty temp stable especially for a ball powder . [/QUOTE]
