You can NEVER have enough ammo. Well, if you can't walk around in your living room because of the ammo crates, then perhaps you do have enough. Until then...
It's been a while since I've counted. I'm a bit down on .223. Probably less than 500 rounds, so I'd best buy some more. Close to a 1000 in .308. Another 500+ in 7.62x39 Those are my main defensive calibers. So I'm not as concerned that I'm a bit short on 30.06, 6.5x55, .303 Brit, and 7.62x54R. Only a thousand rounds or so of .22lr (really should stock up, it's cheap). A bit short on 00 buck (only a hundred or so) and slugs.
Probably 500 rounds each of 9mm, .38, and 45, with the components to reload 500 rounds of each. A bit short on .40. A couple hundred .380ACP.
Guess I need to start ordering ammo again.
