Dear Guys,
The ammunition companies are now sitting on two full years of back orders for 9mm and .223 ammo. To them, it is like gold just sitting there to be plucked. They are also sitting on, and will be forced to fill, the contracts they signed a year ago with the big boys (WalMart, Dicks, Cabellas, Midway, etc.) to provide the annual fall ammo for hunting season in the ordinary calibers (.22, .243, .30-30, .270, .308, .30-06, 7 Mag, .300 Win Mag.) These big boys will readily sue them if they don't fill the orders as promised. The same probably goes for .38 special, .357 Magnum, and .45 auto as well.
With all of this demand in the pipeline for literally hundreds of millions of rounds of ammo in the most popular calibers, they have exactly zero incentive, financial or otherwise, to switch their production lines over to make the limited special runs of the classic but far less popular ammo. By that I mean .35 Remington, .30-40 Krag, .300 Savage, .303 British, 8mm Mauser, 7mm Mauser, .358 Winchester, .444 Marlin and the like. If you look at the Midway website, for example, they say that the earliest that they may get .35 Remington again is March of 2014, next year! Doubtful I say.
So, it appears to me that it may be many many years (if ever) before any of the big ammo makers stop the presses and re-set the lines to make any of the old classic cartridges again. Once things stop getting made, they have a bad habit of never being made again. And of course, the ammo companies have a ready excuse: "Due to unprecedented demand for ammunition, we cannot predict when these rounds will be available again."
Accordingly, these classic rounds may have overnight been relegated to "handloader" status only. But from what I understand, you can't even get the components for handloading anymore.
