OK, left handed. That changes things. The Vanguard does not come in left hand, nor of course the Savage LR Hunter.
You can, however, buy a different Savage in left handed configuration. If so, you can add to the height of the stock to get the proper cheek position. Take a look at the Scope-Eze:
SCOPE EZE - Brownells
Else if you want a LH rifle there is the Remington 700 (one for sale in the classifieds right now) or Wby Mark V or... well, plenty of options, just none in the two rifles you originally mentioned.
