You think you have problems? Here are some of mine, in approximate historical order:

.577 Snider, 11.43x50R Egyptian Remington, 11.15x60R Mauser, 11mm Gras, 11.15x37R Grenzaufseher, .577-450 Martini-Henry, .44 Henry Rimfire... (yes, I have a revolver in that caliber - and it works!)

Hey, is there such a thing as ready-made ammo? Not for my spectrum of old bangers. I can't even find suitable bullets for most of them. And have to be inventive when it comes to cases.

Once upon a time, the ammo you may be looking for was churned out by the hundreds of millions:

"So how many million are you looking to purchase sir?"
"200"
"OK, we can tool up for 200 million."
"No, not 200 million, just 200."
"Sir, may I draw to your attention that this is a factory, not a delicatessen."

So please, nobody cry because you can't buy milsurp ammo at hundredweight prices any more. Milsurp = military SURPLUS, i.e the leftovers when the original armed forces no longer need it. The leftovers have been pretty well consumed. Make your own and get (in most cases) better performance from your old service rifle.
