Here in Central Alabama, I haven't seen any .30-30 available since the panic buying set in. I can still find a little .30-06, but its getting scarce. .270, 25-06, .243, and some others can easily be found.
For handgun calibers, .45 Colt and 10mm are still easy to find. Everything else has gotten hard, if not impossible, to get.
I've been foolin' around with guns since 1980. Never in my lifetime has ammo been this hard to find.
