Hello Folks,
I flyed these days some sorties with the Tank killer Il2. But i didnt't have the feeling that it is a can opener.
Ok... im not the best sharpshooter in the game (rather hitting the target by pure luck or by mistake 
)
The Story: I hunted a T-34 and poured about 80 canon shells in the can - nothing. I used 4 rockets on it and im convinced i did make 2 hits - nothing. I dropped 4 bombs on that monster, and two eggs exploded right by the side of the tank - nothing.
What im doing wrong?

It is all about hit location and angle. Not having film, I don't know what if anything you were doing wrong. High angle, fire at the flat spot on the top of the engine compartment.
As others have said, the T-34 tends to be one of the tougher tanks to kill with cannon only. Had you been hunting a Panzer, Wirbel or Osti, you would have seen more of a can-opener.
As for bombs, again without film it is hard to say. Sometimes it seems terrain features prevent the blast from hurting a tank (hitting the ground above them on a slope, for example), or perhaps your bombs didn't land quite as close as you think. They are only 100kg bombs, not 500 or 1000 lbrs, so your bomb would need to be closer to do any damage.
