"...Is the recoil on 270 higher then(sic) a 7mm mag?..." Think physics. A heavy bullet going fast has more felt recoil than a lighter bullet at the same speed. It's a law.
Typical bullet weights for a .270 are 130 or 140 grains. The 7mm goes to 175 grains. With 140 grain bullet weights, the 7mm starts at 250 fps faster than the .270. The muzzle energy is 474 ft/lbs higher. Higher speed and energy adds up to more felt recoil. However, that does not mean you can't handle it. Stock design and rifle weight reduces felt recoil.
Personally, I'd go with the lighter one. Shooting for the sake of shooting is fun and you have to sight in and practice. Heavy felt recoil reduces the fun of shooting for normal people.
Oh and you don't need any magnum anything for deer. A 130 grain .270 bullet will drop a deer like a ton of bricks if you place it properly.
When you get your rifle and assuming your not reloading, you'll have to try a box of as many brands of ammo as you can to find the ammo your rifle shoots best. Then sight in with that ammo and practice, off hand(standing), at 100 yards using a 9" pie plate. When you can hit it every time, you're ready to hunt. Everybody who shoots anything with factory ammo has to do this. No two rifles, even two identical rifles, will shoot the same ammo the same way. It has to do with the manufacturing tooling, not the shooter.
And buy your ma something special for Christmas. Most mom's would defecate bricks if their son even thought about having a rifle.
