Are all 7mm Remington rounds of the magnum persuasion and can I order some online?

I'm the owner of a Rem. 770 bolt action chambered in 7mm Rem. Mag. My ammo is rather expensive and I was looking on Cabela's website and I saw some bulk rounds (quality isn't a problem, I'm a target shooter mostly). Here's the listing:... show more I'm the owner of a Rem. 770 bolt action chambered in 7mm Rem. Mag.

I was wondering if the "7mm" option is the same as a 7mm Mag.
Also as a secondary question I was wondering if it was legal for me to order ammunition in the communist state of Kalifornia. Your help is appreciated.
Update: I got this gun because in the area where I live hunting is very common and before owning this rifle I didn't have a large enough gun to go hunting for most game.
