Picture would be nice with just a tad of history on the round.

Thanks for posting. I always wanted to know what these rounds looked like. And i believe they don't use them anymore. Something about barrel failure when using them.

the newer ones are a red plastic sabot They have a tungstine carbide pin in the sabot not a regular bullet like that.

The problem is that Carbide and really hard metals are brittle so when these impact at high velocity they shatter and turn into dust. It will penitrate but may not do as much as you think. I wrote up a review and fired three rounds into extraa Rifle plates I had.

Sorry, got as far as posting pics when computer cut out.  The first pic at top of page is the M959-SLAP-Tracer 7.62x51 headstamp WCC/90/SLAP.  Its a M196 red tracer in a plastic sabot for matching the same trajectory as the M948 SLAP with the tungsten carbide penetrator.  They both travel in speeds excess of 4000fps after discarding the sabot about 20 feet from the muzzle.  
Mike, that was me stating that the military had stop useing these after they were having catastrophic muzzle failures.  However, I'm usaully wrong, and just read that the Dept of Defense just ordered $43 million worth of the .50BMG SLAP for the US Army.  (from the NRA magazine article) Was hoping to see if you were going to complete those tests, I'm too cheap to shoot any of mine.

These are pics of the M948 SLAP with headstamp WCC 85 SLAP.  It has a non ferrous tungsten ceramic carbide core with a Vickers hardness of 1450 (armor plates starts around 500)  Thanks for looking.  wolf

I threw out the plates I shot because they were leaking ceramic dust everywhere when I moved them. I intended to see if I could recover any of the projo after it penitrated an undamaged part of the plate and into water jugs.  

That'll probably never happen now, Im willing to shoot two more slap rds 90s production. Let me know what you want to see hit.

What are you using to cut these?

Probably ground down vs cut, belt sander works nice except on tungsten carbide

Yes grind, not cut.  Depending on what is being ground, water is also used for like tracers, incediaries, etc...  The tungsten is so hard that a wet diamond blade did not even scratch it.   Got about 400 different sections, and just finishing a 100 round collection of 7.62x39 for someone else.  Going to think about what you should shoot at, need something good.   wolf

AR500 at 100 yards 3/8", 1/2, 5/8" etc until it stops, then cut/frame the piece with a penetrator stuck in it.

I'll bet it'll melt through mild steel like its nothin. Armor on the other hand I doubt it'll go very far.
