There’s something to be said for the KISS principal. You know, Keep It Simple, Stupid. I’m certainly guilty of ignoring it in a lot of areas of life. Ammo isn’t one of them. I’ve chosen most of the guns I’ve bought (and avoided buying others) based on the desire to stock the fewest, most popular and (let’s face it) least expensive calibers. Not everyone follows that principle. Many don’t even give it a thought. Does caliber, availability and cost influence what you buy? Are you willing to hand load ammo for an esoteric gun you own? Does it even matter?
