A type of Rifle round (.30-30). The 150 is the grain. Not sure what that guy is talking about with the whole rape thing, couldn't find anything about it.

Also, the name of the first track of Stone Sour's album "Come What(ever) May."
My Remington fires a 30/30-150.

Stone Sour's new song 30/30-150 is awesome.
