I have a 7x64 and a 30-06. I dont think the recoil is different enough between the two to make a difference. If you dont think she could take the recoil of an '06, she probably wont like the 7x64.

For comparison, my 7 is a 24" Howa in a McMillan and the '06 is a 24" Ruger in a McMillan. Scopes are both 3.5x10x40's. They are probably both very similar in weight. The 7 shoots 140's jsut below 3000 and the '06 shoots 165's at 2800ish.

There is no way to coexist no matter how many bumper stickers there are on Subaru bumpers!
