My list is:
1. A traditional black powder rifle or smoothbore (shotgun or fusil). A bit of respect for those who came before and were the basis for this country.
2. A good .45 SA revolver. Same reason as above
3. A .38/.357 K or L frame
4. A .45 1911
5. A CZ75- one of the best 9mms designed
6. An 870 or 1100- your choice. Wonderfully modular and reliable do anything shotguns.
7. A Marlin 336 in .30-30. IMO the best lever action made
8. A Marlin 60 or 995. Both are superb .22s
9. A good bolt action .22. CZ is one of the best currently made
10. A Ruger 77, Model 70, or Savage 110 in a good hunting cartridge like .30-06
11. A 20th century milsurp rifle, 03, Garand, or 98 Mauser action-your choice
