I was listening to the radio and caught the lyric: "You don't have to live out in the sticks, with an F150 and a thirty ought six" It got me to wondering how you would explain how universal the 30-06 is to somebody who knew nothing about guns. So picked the Tool Analogy. I would say the 30-06 is like a 12 inch adjustable wrench, it might be a bit too big for some bolts, and a little too small for a few of the big ones, but it will work on almost everything. Any other cartridge/tool comparisons? 22 LR? 45 ACP? ETC?
