Marakhtanovs have been doing this research for several years.
It appears that 'the impact of a bullet can induce transmutation of bismuth to platinum..
Mechanical Impact on Metal: from the Destruction of Crystal
to the Transmutation of the Nucleus
Marakhtanov and Marakhtanov, Res Rep Metals 2018, 2:
""It has been experimentally established that dusty products of
an inertial explosion of the projectile containing a
bismuth alloy emit single α-particles with energy of ~ 8 MeV [10].
Spectral analysis showed the presence of platinum and boron.
Of course if one were to ask the DOD if this could happen
with depleted.uranium tankshells they would
probably say IMPOSSIBLE... if anything..
