I'm surprised no one has mentioned the softening of 7mm mag data as of late. Oh...and some of the first wsm stuff was wimpy as could be too.
I love quick load, old manuals, and new manuals. I can jump back and forth and come up with a compromise. Once I use a powder in a few cartridges I can balance it with quickload and see if it's on track. To be honest quickload has definately been "on track" much better than the newer manuals.
