If that needs to be used on you you're in trouble...

One of the reasons to not use PVC in gas pressure or a fireworks tubes. It shatters into sharp pieces that the above machine and x-rays don't see. If you're going to be perforated, best do it with steel that is easy to find and remove.

I wonder about the plastic tips on modern hollow points, especially the red ones. How do you find those while dissecting your specimen?

This Hirtz process somewhat an improvement.
Old way, doc poked around and asked "this hurts?".

If you answered "yes" at least you were still alive...

Dependent on specimen, it's so common for a projectile to pass thru after expansion, and some have a bit of cavity behind said ballistic tip. It could be located in ballistic gel, somewhat readily.

Yeah…they don’t use that in surgery. Never seen that in 30 years.
