[QUOTE="shinbone, post: 2536043, member: 15248"] Looking at Nosler load data for the 125gn Ballistic Tip in a .300 WSM, N550 seems to be the peak for speed and accuracy of the 10 powders tested. As usual with the slower burning powders, the challenge is stuffing enough powder into the case to get good velocities. N550 is close to, if not at, that limit. The Nosler data shows their max N550 load at 102% load density, meaning it is slightly compressed. Considering all-copper bullets tend to take up a little more case volume, powder compression could be the reason that my previous load work with N550 stopped a 69.5gn despite no pressure signs. Looks like I definitely need to redo my N550 load workup at the higher end. And go in smaller powder steps, [I]and take better notes. [/I] [/QUOTE]
