I became a hoarder in August of 2012.
I use the Internet and also visit LGS often. At LGS I buy what I can and not necessarily what I need. Right now, primers and powder are in very short supply. I can buy brass and lead cast bullets but only at elevated prices.
The choice is obvious; be a hoarder or wait-out the shortage which could take a year or more. Component prices probably will not return to pre-shortage levels.
Therefore, it does not make sense to wait it out.
