IfI was in your situationI would buy either a Savage or Remington with wood stock.
Iwould cut the wood stock down and add a good recoil pad for the smaller stature shooters and get myself an aftermarket stock.

I prefer the good ol 30'06.
I think if a person cant kill what they wanna kill with a .22lr a 12ga. and '06 they might as well hang up thier huntin' hat.
I own a couple magnums they are nice but not necessary.

Although I feel that the .308 Winchester is better suited to your needs.

My opinion
