It does indeed rupture, but with the light weight it doesn’t have much force behind it. You get possibly one or two pieces of metal detaching, rather than a fanned out fragmentation spread, with a large surface area but lightweight piece rather than small dense pieces that will go further and faster. Hence words like “minimal” rather than “none”.
And where, exactly, does that “thin bodied metal” go when it explodes?
