303 ammo

[Bruce_in_Oz]

The ONLY "service ammo" that was "non-corrosive" before about 1950, was .30 Carbine, and the only reason that happened was because of the "non-user-serviceable" gas piston setup. (Beware of the odd batches of Chinese Carbine ammo made in the last couple of decades; definitely corrosive. Come to think of it pretty much ALL "Eastern Bloc / Chinese" and "client" sourced ammo is corrosively primed, but it works fine and your guns won't rot away if you use it, unless you fail to perform correct cleaning practices.

If you are in a very dry place, like Northern Canada in mid winter, or the middle of the Atacama Desert, not a problem. If you live in places like Florida, coastal Queensland or similar, you will hear the rust forming overnight.

The stuff is NOT mercuric primed, thus it is reloadable brass. Better to sell it as "collector" ammo and buy nice new commercial brass and primers with your winnings.
