You will really enjoy the 7mm mag, Bill. It's an extremely versatile caliber, with a broad range of bullet weights available. They are very easy to handload, not being temperamental in the least, working well with virtually any slower burning powder and appropriate bullet weights.
That said, it has about the widest disparity regarding charge weights between the various loading manuals. More than most other calibers, a good chronograph is your friend in helping you understand where your particular rifle lies in the spectrum of rifles so chambered. Throats vary widely from manufacturer to manufacturer, which is what contributes to the seemingly contradictory information from one manual to the next - often one manual's starting load exceeds another's maximum load with the same powder and bullet. It all depends on the rifle or test barrel used to work up the data. Once you figure out where your rifle is, though, they are a real pleasure to work with. Have fun.
