In Regards to the M4/75mm performance vs the 76mm on the T34 using data supplied from AH:
Gun Penetration (mm) 0k 1k 2k
M4/75 91 80 70
T34/76 90 75 63
T34/76/HVAP 124 82 55
So in other words my memory was right on.
That is just the AP data. That does not even take in to consideration the reload rate or the optics. Oh, and the HE damage the US 75mm provides another 30 lbs of damage as well.
Yeah, I still think the KV-1 would be a sitting duck even more so than the M4A3/75mm since it is about 6-7mph slower. The KV-1 obviously has better armor, but once the US76mm and better is brought in to play it matters not.
Edit:
Regarding the performance of HVAP ammo: the round relies far more on velocity than it does weight hence the inability to maintain enough kinetic energy over time. Most people keep firing away with their HVAP ammo at targets well beyond 1200 yards because they do not know better. Up close there is not doubt, use it.
