After the recent discussion regarding the FMJ (made by Simrell) and making DIY copper sleeves for the DV, I thought I'd do a little reading about it all. My original intent was to see if others were pleased with it's performance. But the web is always a rabbit hole and I stumbled upon a few things that had me scratching my head and looking further.
Since folks wanted to DIY... I looked at this thread first. While no one seemed particularly concerned in the thread, I was a bit concerned about the image in the first post...
The copper 'sleeve' has oxidized. As has the FMJ that I found in this thread.
This is alarming to me. Inhaling copper oxide nanoparticles can be toxic.
My first search found this article....I have asked the authors for the full article. But this sentence stood out to me:
A Google search of 'is inhaling copper oxide toxic?' brought up this sheet written by "an international group of experts on behalf of ILO and WHO." Note this portion:
So the question becomes... are there nanoparticles of copper oxide going into the air path of the DV when you heat the copper sleeve to the point that it oxidizes like this. Something to think about.

CuO nanoparticles were most potent regarding cytotoxicity and DNA damage.

Effects of short-term exposure
The substance is irritating to the eyes and respiratory tract. Inhalation of fumes may cause metal fume fever. Ingestion could cause effects on the kidneys and liver. The effects may be delayed.
Headache, cough, sweating, nausea and fever may be caused by freshly formed fumes or dust of copper oxide.
