At least Federal brand has always been spotty for availability. Dealers get in one huge shipment every several months, no consistant supply. When they show up again buy a couple cases. They're cheap enough, if stored properly wont "go bad", and a few
thousand should hold you a while.

You want to do it that way for "lot consistancy" anyway!
ccd, and deamonpi make good sense.
Have you seen the price of bullets lately?! Thats what I ran out of. Cant bring myself to pay more for bullets than I did a year ago for loaded ammo!! I'd consider casting (as you do), but the jackets have to many benefits to me.
