I have been keeping more ammo on hand than I have in the past primarily because the prices started to rise. Now it's more difficult to just walk in and buy what you want when you want it, it's turned into a darn Easter egg hunt.
I have a buddy at work that's been making me reloads which has helped out on the "frequent fire" calibers.
Rifle / 2900 (mostly .223)
Handgun / 750 (mostly .45 and .38 super)
Shotgun / 110 (all 12 gauge)
