One can at most wield two firearms. And one is most effective concentrating on just one. The booger eating mouth-breathing MAGAts may own many more guns than the rest of us. But they can only use one or two at a time. And lots of us ALSO own some firearms. We just usually don’t make a fetish of them. Furthermore, owning a bunch of different caliber weapons complicates your supply issues. I have concentrated on 7.62x51/.308, 12 ga, and .45.
