Lead Projectile Core Marked "JP" Over "124"

I'm reading an autopsy report at the moment that describes a lead projectile core recovered from a body as being "inscribed" with the letters JP over the number 124.

Does anyone know which ammunition manufacturer marks their cores in this way, and what the markings mean?

I figured the 124 may mean 124gr, but the only casing recovered at the scene was a .40, and the docs did not attempt much in the way of measurement of the projectile as it was extremely deformed.

It will be another week before I can inspect the projectile personally. Any info will be greatly appreciated.
 
Bump.

It's very unusual, I've never seen writing of any sort on small arms projectiles with the exception of an "F" stamped on the flat tip of Federal EFMJ bullets.
 
it could be marking placed by the discovering officer (JP) and his/her badge number (124). Cops used to be taught to do this, scratching their initials and badge numbers into high value recovered stolen guns, cameras, etc.
 
Thanks.

Saw a photo of the projectile today and couldn't see anything like the markings described in the report, but it wasn't a very good image.

I should see it in person tomorrow, and will have the doc available for inquiry...
 
Could it be a 124 grain lead core from a 40 caliber 155 grain "Jacketed Projectile". Swaged bullets have a thicker separate copper jacket which alone weighs 35 grains in a 230 grain 45 caliber projectile, so I can see the 40 having a 31gr. jacket which separated from the core recovered. I know it's mangled but the core should only be .39 diameter.
