Seen some interest in this topic, so I'll repost my findings from ~ a year ago.
"OK, the results of our findings.
At ranges up to around 150 yards, if the T-34 is exactly perpendicular (within about 2 degrees) to the surface it is shooting at on the Tiger (rear or side) the round will not ricochet. It doesn't seem to do any damage either, which is about right, considering the upper range of its penetration is just about the thickness of the armor on the Tiger.
Inside of 100 yards, it seems that 3 hits to the same panel (the Tiger has a hexogonal turret, front, 2 front side, 2 rear side, 1 rear "panel") will disable the turret. It was always 3 hits, every time we did it (many many times). Again, the T34 shot must come in almost directly perpendicular to the panel you are shooting at, or the round will ricochet off.
Shooting at the rear never knocked out the engine (well, perhaps I just didn't have the patience to do it). Shooting the side (hull) about 12-14 times seemed to kill the Tiger. Shooting the Tiger a seemingly random number of times after the turret was disabled killed the Tiger. These hits didn't necesarily have to be to the same panel you hit 3 times to knock out the turret, sometimes one hit to an undamaged panel will kill the Tiger if the turret is already disabled.
Should a T-34 catch a Tiger with a roof shot (seemed the threshold was fairly steep, we were unable to replicate this other than by having the Tiger basically tip himself over one of the flat sided hills used to get hull down with), it can kill it with one shot inside of about 1500 yards.. takes 2 at that range. I don't see this happening in the MA.
I'd still like to have the BR-350P round modelled with a limited number of rounds per load (4 seems nice, and historical ), simply because I think it is exceedingly unlikely any Tiger would sit still and let a T-34 pound out 3 shots at the exact same panel of the turret without moving either the tank or the turret even slightly.
It is possible for the T-34 to kill a Tiger however, if the Tiger driver is cooperative enough."
Basically grabbed a friend and went to tanktown in the DA.
