Yup listen to the myth of tiger gunners that would come back with hundreds of hits but alive.
Does that mean a tiger gun will kill any tank at any range no matter where it lands? Nope. That's just complete bolloks.
You guys really have to stop to take individual anecdotic accounts and produce extremely overgeneralized and wrong statements.
With you logic, I could claim "some 109 pilots did kill hundreds of enemies - the Me 109 was superior to all fighters and would always shoot them all down."
Tiger rounds did ricochet of simply fail to penetrate, depending on range armor thickness, sloping and shot placement. The Tiger was a fearsome enemy, but not the "awasome invincile supertank" of newspapers, movies or cheap TV shows.
And if you would really look at the armor thickness values of WWII tanks you would notice that the M4A3 did not have "thin armor" at all.
