I was going through my ammo and discovered about 30 of these. They appear to not be completely jacketed but do have a visible lead center to the slug. Somebody please tell me what I have here. They are only marked as Win 9mm Luger.

Thank you. I have no idea when I bought it, but now I will use it at the range since it is not hollow point.
The early non-toxic primers had a VERY short life expectancy.I got hold of a box of the .40 version, same bullet style, WinClean...no idea how old it was, but about a third of the rounds failed to fire, with good primer dents, and multiple tries. Something about the non-toxic primer didn't quite work out.
