A new monolithic bullet has arrived in Germany, an interesting two part construction (threaded?) concept.

I assume its to stop the copper from unscrewing.
Interesting.
The advert states - Alternative copper bullets often have the problem of precision: they are often manufactured using a simple press-upsetting process; the concentricity is then often suboptimal, which then results in a loss of precision.
What it fails to mention is that many copper bullets, I do not know if all are or not, are produced on Swiss lathes and have concentricity better than non-lathe turned bullets, copper or otherwise.
Here, the manufacturer has achieved a pure, mechanical connection between the hollow point bullet tip and the brass bullet tail, which requires no chemicals other than contact adhesive.
The contact adhesive, would it not be a chemical? Surely, if there is a contact adhesive then there is not a pure mechanical connection between the two metals.

As i read the OP the cavity was from the rear of the copper top part rather than traditional HP.

Most modern barrels are RH twist, so with a RH thread that won't be an issue as the reaction torque will tighten the thread
"Most" that's reassuring!!!
Tends to be older rifles such as Enfields that have a LH twist, I think? Or I guess a custom build could be specified as such? There's a train of thought that theorises a left hand twist can counter the natural tendency for a right handed shooter to pull the barrel to the right. How much truth is actually in that theory I wouldn't know

How long, perhaps, before the Glaser Safety Slug gets re-invented with copper shot filling instead of lead shot?
Two metal bullets have been around since some big game hunters first started casting lead bullets with cast in iron tips, since Remington's famous "bronze point" bullets and of course since the German TIG and TUG bullets.
Albeit these new offerings don't use lead but the recently the redesigned non-lead PRVI GROM bullet also doesn't use lead but is using tin. . But it's merely surely re-inventing the wheel?
My concern would be that on impact the two parts would separate and not perform as they are supposed to perform.

ha I still have a few .45acp Glaser Safety Slugs from back in the day over here in sunny overseas.

This might interest some on here with an interest in how lead free performs and a few hours spare.
80 pages long with many pictures of real life expansion.
