My reply about this tank from an other post:
"The VK 3601 with the Waffe 0725 gun would be an absolutely useless tank, due to the gun. Why?
Well, it is a squeeze bore gun, there is already one in the game on a german car. The problem is, that the shell is modelled as APCR.
Now since the last APDS nerf, even APCR started to shatter on everything, and deal absolutley no damage, even if it pens.
To top it all up, Gaijin would implement something like a 6 round ready rack for the tank, and with that 6 round, you might destroy a light tank, and after that, your rate of fire will be horrible, with absolutley no damage.
If gaijin models it as a solidshot, then that tank maybe could be good, since the penetration is close to the Panther’s penetration. But even as solidshot, the damage will be bad at best, so the tank should not have a ready rack (so the reload time does not change depending on the ammo rack location), and a faster reload time, maybe 5s aced, but 6s aced maximum.
The armor would be somewhat OK, but since the side armor is 60mm, you can’t really angle it.
The turret is a Panther-like one, so the mantlet in the middle is ~100mm or so, this means at close range potentially even the american 75mm will pen it, not even talking about the cupola.
So it is a Tiger with everything good taken away from it. Armor, that you can’t angle, no magical inpenetratable mantlet, bad damage.
I would say maybe 4.7. At 5.0, you have the Protopanther, and that is just a better at being a “heavy tank” than the VK 3601."
You have mentioned the 10.5cm and the regular 7.5cm guns.
I would say none of them would make this tank usable.
For my bet, i would say the best option for this is the Waffe gun, but the shell modelled as full calibre solidshot, and the tank could be at 4.7 max. The tank would be bad, but at least usable.
