Well, maybe you know nothing about anatomy???

If a pellet entered the bloodstream, it will eventually travel to the heart. However, that is not what they are saying happened. The Doctors said it was lodged near or in the heart muscle, which caused inflammation, or a silent heart attack.

So a "peppering" (look up the definition) of bird shot can enter thru the mulitple laters of cloth, then skin, then muscle, to lodge against the heart.
The magic shot theory.
