Interesting parts:
Depth of penetrations: 60mm.
In the 1943 trials on Tiger I this gun (well technically the F-34 gun on a T-34 tank) achieved:
Distance: 400m,
Shell: AP
Target: Side.
Results: Dent 35mm deep.
Distance: 200m,
Shell: AP
Target: Side.
Results: Dent 40mm deep.
and this is against a vertical plate, while here it achieved deeper penetrations against a plate of same thickness sloped at 25° (provided the measurements were taken in the same frame of reference). Could mean this gun was using BR-350B shells with better integrity than the early models.
