A quick search on YouTube will bring up several videos of big game, deer etc dropping dead as they were shot with a .50 cal. This might sound unsurprising , but in every case the round missed. The animals were not hit. The shockwave killed them - eyes ruptured and lungs trashed.
I cannot say unequivocally that this armor won’t stop a .50 cal as I have not seen it, but I would be absolutely amazed.
