I will echo the above sentiment regarding caution with the selection of the 7 mag, given that you say you are new to centerfires.

That's not a cartridge to "learn" with, formost shooters.

It's very easy, with a lightweight, magnum hunting rifle to develop a flinch when shooting- that can be difficult to undo.

Even if, it's what's needed for your hunting application- you likely would be better off developing basic marksmanship skills, trigger and breathing control, etc. with a rifle that's not going to pound you.

What is your specific application that led you to select the 7 Mag?
