[QUOTE="rlspahn, post: 2298280, member: 11120"] Each bullet will be different. For a given cartridge in a given barrel length, moving to a lighter weight bullet may require a faster powder to achieve maximum velocity. I ran into this with a 7 SAUM improved. I could reach max load/pressure with H1000 and a 180 gr bullet. When I tried H1000 with a 155 gr bullet, I couldn't reach max pressure with it as I ran out of room in the case (case fill exceeded 100%) before I reached max pressure. I moved to a faster powder and was able to reach max pressure with a resulting higher velocity. There are a lot of different factors that have to be considered, each with their own impact on achieving a desired result. [/QUOTE]
