fair enough. My calibers right now are 9mm .45 acp and .223/5.56.
I don't see myself adding any others for a fair amount of time. I rarely shoot .45 because of the expense and only having the 1911 chambered in it.
I mostly practice with my rifle with the .22lr conversion in, cheap and close to real life. I always end my rifle sessions with 60 rounds of 5.56 practicing malfunction clearing and proving accuracy.
9mm is my carry and game ammo, it's what I order most often.
I can't convince the old lady that throwing out the spare bed in exchange for reloading equipment is a good idea. Maybe when we get into our first house I can have a man cave but until then, I'm lucky to have what storage space I do.
