An elderly relative of mine who wanted to clear out some ammo before relocating to a condo gave me a bunch of .303 ammo pictured below.
Boxes are paper sealed and this is the box with the best labelling not too faded to take a picture of. Dated 1941. Is this collectible ammo or should I just go ahead and use it at the range? Is it corrosive? Thanks for the advice guys!
