Ok now, what the heck are these and who made them? As in a company if anyone knows.

Do I use cast data or jacketed?

:headscratch:An abomination. Guessing there for 9mm. Hollow base is to slug up to bore. I would use cast data, since the jacketed portion is above the cannelure. What do they weigh?

not very well made either.

MY opinion is they are a flipped over half jacket swaged to shape and the cannelure is there to try and keep the cup in place.
the die would be a 2 part [halfs] that squeeze together.
i dimly recall Herters maybe? offering something like that in the past.

Like CW says, sure look like some of those factory AP bullets from the late 70's or so. I never shot any and recovered the bullet. That takes me back a looong way.

After some google-ing, looks like mid-70s Winchester 158 gr "metal peircing"

Federal law (which only regulates the commercial manufacture or commercial importation of pistol-caliber AP projectiles) states that the projectile or projectile core must be made of brass, bronze, iron, steel, tungsten etc. or harder to qualify.

Strange indeed!

Thanks for the help fellas!

Okay, guess that's it. From an era when shooting "at" the vehicle was okay. That stopped being kosher at least 35 years ago in my agency. In fact we had bi-annual classes where we were told in no uncertain terms that unless someone in a vehicle was shooting at you, you could not fire on a vehicle- period. I think it went back to some cases where innocents in the vehicle were hit, so it makes sense. I heard a rumor that has been modified, but it's just a rumor.

Took me a minute to figure out what a "projo" was too. Is that a common term now?

I thought those bullets had a real “homemade” look about them. Wrong again!

Now I remember those! The cutaway view jogged my memory.

I have to wonder what this would do that the .358 version of the 429303 wouldn't do. I have one of each but never shoot them any more. The 303 was purported to penetrate 3/16" mild steel at so many yards and there was a gun mag article on it way back.

"Projo" (projectile)is pretty common terminology in the Field Artillery community for at least the past 35 years that I've been associated with it.

I am looking at these and wondering what advantage they would have with regards to penetration over an ordinary FMJ? Any?

If memory serves me, didn't J Edgar task the industry with coming up with a semi auto pistol which would penetrate car bodies of the era and that is now why we have the .38 Super?
