I read that he was shot, Ill look through my books but I am pretty sure it was a bullet.
He just died in 2002, little guy too, 5'3"!

Both. He got shot in the face with an exploding bullet - and still killed the sniper who shot him before going into a coma.
On the Eastern Front during World War II, both German and Russian snipers were officially authorized to use explosive spotter-type rifle ammunition (B-Patrone for Germans, PZ for Russians) on human targets. The projectiles in the ammunition contain a charge of highly reactive phosphorus and a priming compound, and explode on impact.
