handyman,
This post of mine is NOT meant to be facetious nor smarmy in any fashion so I hope you don't take it that way.
The reason there is a shortage of ammo right now is because Obama has recently been elected to office.To put it bluntly,people are panicking.Whenever a bad ice storm,etc is forecast for the area,everyone runs out and buys bread,milk and batteries (same principle).
The panic will end at some point and I'd recommend you "stock up"when it does.Having something on a shopping list is just empty air.It's far better to actually have it.
I haven't bought any ammo or components in years.I haven't needed to.
