... I suspect a .243 would be effective medicine for them.... . You might consider adding the .260, 7mm'08, and the 6.5x55 Swedish to your list of possibilities - all very mild mannered and capable cartridges cartridges..... .
If your going to all this.Get her at least a Browning.
I have another option for you based on my wife's experiences shooting island deer. Lots of island deer.....
Browning X-bolt Micro Hunter in .260. (my wife actually shoots custom loads in .308, but if we had it to do over again I think we would get a .260)
It fits her well, looks sharp, is wood/blued and shoots really well. The gold trigger isn't really needed, but seems to make a girl feel special. I topped hers with a Vortex Viper 2-7x32 and she smiles every time we get it out of the safe!
