I did, but only because I just picked up a .44 carbine and I needed, among other things, dies, brass, and bullets.
But as far as .22, .380, .38/.357, 9mm, .45. .223. and 7.62, I've got what I think I need in reserves. I got into reloading a few years ago and I'm glad I did. Now when I start running low on factory ammo, I've got enough to keep cranking out ammo as I need it.
If things get really bad, I'll adjust as needed and maybe shoot a majority of .38 special and scale back a bit on other calibers, but I can more or less shoot and reload for years to come....
