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.

Winchester Winclean.

Winchester WinClean Ammo 9mm Luger 115 Grain Brass Enclosed Base

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.

Back 20 years ago or so, I also got a Speer 124gr that looked like that.......
it is not made any more.

Lots of things are not made any more............
Now we shoot coated bullets....... what's next ?

I prefer a bullet of this type for a defensive round, it will penetrate deeper before starting to expand than a full hollow point will. Some hollow points will start to expand as soon as they hit the bad guys clothes and only penetrate a couple of inches. A painful wound for sure but not lethal, a consideration in the winter when the bad guy may be wearing heavy clothing.

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.

The early non-toxic primers had a VERY short life expectancy.

The factory loaded ammunition should have expiration dates. If I recall, the Federal ammunition had the date on the full cases and not on the individual boxes.

That's an old misnomer that is getting re-looked at by lots of folks today. Flat points or truncated bullets transfer a lot more energy into the target, causing a lot more damage. Pictures of soft points opened up are pretty intimidating, but there are mitigating circumstances. First, even with thin jackets, it takes velocity to get a hollow point to open up. Some handguns don't provide that velocity, especially out of a snub nose revolver. Next, some have such thin jackets to overcome the velocity issue that they open up and fragment and these fragments, lacking density, lose velocity, thus effectiveness rapidly. One of the major gun magazines put out a very interesting article on it a few months ago. The only two magazines I subscribe to are American Rifleman and American Handgunner, but I think it was in the Rifleman.

The flat nose bullet isn't anything new on the ballistic scene, invented well over 100 years ago, but for some reason was overlooked by the home defense crowd. By not fragmenting, or losing velocity to the forces required to expand their nose, they transfer all their energy into the subject while providing a nasty wound channel that outperforms same size/velocity hollow points. What zonker5 said is true. Lots of ammo makers are making the switch back to these bullets for their handgun defense ammo.
