The 75mm KwK 37 L/24 gun (short barrel) has less power than the 75mm KwK 40 L/43, which has less power than the 75mm KwK 40 L/48 (currently in game). The F-34 tank gun on the T-34, overpowers the short barreled L/24 easily... and depending on the ammo used (AP or HVAP) varies against the L/43 and L/48 gun.
You can get all the armor penetration ratings and compare them here:
The Soviet 76mm F-34 tank gun has less AP capability than the M4/75mm, just food for thought.
Also, at 1000 yards, that same F-34 76mm only has 10-12mm more AP ability than the short barreled 75mm on the Panzer IV F (75mm KwK 37 L/24), hardly much worth mentioning, imo.
The T34/76 has a leg up in 1v1 tank duels against the Panzer IV F because of its armor more so than its gun.
Also, HVAP loses any advantage once ranges of 1000-1200 yards, it simply does not have the kinetic energy to punch through. So at ranges beyond 1000 yards, the Panzer F2 and H have a distinct advantage over the T34/76. The HVAP brings the T34/76 up to par with the other tanks. Heck, the H has better AP ability than the T34/85 and M4/76, yet we'd never know it in AH, at least with the current version (never seemed to get the job done like the M4/76 or T34/85). Hopefully, the new model will be more on cue with its true capabilities.
