Buy it from where? I have a handed down .30 cal M-1 carbine, it has been more years than I care to think about since I bought any ammunition for it. Locally Cabela's--- nope. Bass Pro--- nope. Wally World--- nope. A mom and pop gun shop that would be a nope. I am not a gun nut, I would like to have say a 50 round box on hand for use against varmints and such.
