I've also seen 40 ammo come down in price as well. I think I've seen it online for 11/12 a box.
I've been getting it for $10.50 a box through http://targetsportsusa.com. That's their club pricing on Remington UMC ammo. Makes reloading .40 much less cost effective, so all of my .40 reloading efforts have been directed towards 10mm now.
