Bob H in NH

I know, hard question "which kicks more", so let me try this.

I am getting a rifle for my wife, the goal is to use this for the next 10+ years all across north America hunting, we have "dreams" to hunt whitetail, mule, antelope, elk.

By far the most use will be NH whitetails, so 100 yards is a long shot, but we want it to be suitable for up to elk out west.

I have a post elsewhere on the specific rifle, ignoring caliber, so now flip question.

Given the same gun, which fits her, can anyone rank the recoil of several suitable calibers (also, are the below suitable for deer to elk, also any others)

.30-06
.308
7mm Mag
.270

We don't reload so off the shelf bullet selection is important.

I carry a .30-06 and have no issue with having a second one in the house, but not opposed to other calibers as well.

Thanks
