I would say that you need a few fireams just to get by with.
Kimber-22lr.
Savage Accu-Triger/Accu-Stock rifle chambered in 223
Remington Model-700 30-06
Remington 870 Wing Master 12-gauge shotgun
Kimber Model 1911 45-acp pistol.

I would also add to the list if it fits into the budget a custom made rifle. I myself would like a Cooper or Nosler custom rifle chambered in 338-06 or 280-A.I.
