Jim Carmichel had the solution. He has every scope ring and base since the invention of scope rings and bases, and they are all in their original packages in file cabinet drawers, by alphabet.
Keep everything assembled. Tape base screws to the bases. Label everything. Re-package everything. And when, in hunting camp, you need to change scopes, do it over your bunk or your sleeping bag so when you drop the little ring screws, you'll be able to find them again.
