Yo,
An acapulcoite might have a chondrule, but a lodranite, given the
increased metamorphism, highly doubtful.
That's what differentiates lodranites from acapulcoites - larger grain
size due to more intense/prolonged periods of metamorphism.
I would say a mesosiderite - compare to Clover Springs or Vaca Muerta.
 I suppose it could be a CB/CH, though - but the olivine would suggest
otherwise.
Nice find, regardless.
Regards,
Jason
