"Now lets pretend that for some odd reason you have to replace your belongings in a couple of days and still be prepared to hunt/shoot like you normally do. That will rule out custom jobs and oddball options."
I suppose if I only had a couple of days to get another starting point I would buy and scope an "off the shelf" Ruger or Winchester rifle chambered for one of the 375 cartridges, a Remington 870 12 gauge shotgun, and a good 1911 style pistol chambered in 45. That should give me some breathing room and time to plan the replacement of everything else.
