I recently upgraded my office/gun room (thank you thank you) and was forced to go through my paraphernalia that I have accumulated in the short time I have been reloading. Impressive how quickly that stuff adds up! Anyway, I came across this old round in my ammo storage and I don't know what it is and don't remember where I got it. It's stamped W•W and appears to have an aluminum tip. Any help is much appreciated. Thanks!
