That’s the unfortunate side of US designations. They tended to keep the same designation, even after some changes.
We could say M82 and M82 SC for the 2800 fps variant.
Yeah, but at least in the past the game used to use /L after names for later things, such as the B-17E/L or Typhoon Mk Ib/L. In my opinion the whole word “early” or “late,” such as the T-2 Early, looks really ugly lmao so basically anything that can keep the whole word out of a name is cool
That’s fair. M82E, M82L and M82SC would be fine with me.
Now, the issue is getting Gaijin to implement these rounds.
What does SC stand for? I’m assuming it has nothing to do with time like early or late, so it must be something with the shell
Supercharged. Because there were actually 3 different tested velocities for M82 (2670, 2800 and 2850 ft/s). 2850 ft/s was discarded as it caused too much barrel wear.

The initial M82 was fired at 2670 fps. The plan was to increase the velocity to at least 2800 fps. The 2800 fps variant was adopted and labeled Super Charged to differentiate it from the earlier M82. A version at 2850 fps was tested but wore out the barrel faster.

It seems that the M82 shell will not pen a ~200mm/0° plate, even when fired from the long 90mm gun. Weird. Has this been discussed on the old forums? What was the consensus?
Yeah, it’s known the M82 could not penetrate 8” of 220 BHN plate. The T50 was developed to improve performance of the long 90mm.

This chart is difficult to read but M82 could not penetrate 8” of BHN plate. PzGr 39/43 penetrated the same plate at 2735 fps for army and 3081 fps for navy limits.

Maybe different steel has different properties?
I don’t think you can come to this conclusion based on the German 75mm Pzgr. 39 chart.
And 150 kg/mm² plates appear to offer the best protection as aircraft armor.

Somewhere on the old forum is a decluttered version but I don’t remember who posted it.

It was meeee! :D
Lemme find it for you. Here, I still had it saved:
@KillaKiwi Those numbers in (kg/mm^2) is the tensile strength of steel, not its BHN. 100kg/mm^2 is ~300BHN

Comparison of 8.8cm Pzgr.39/43 and the 90mm M82 shell’s penetration performance:
The T50 shell performance would’ve been be almost identical to the red curve.
Edit: Cool pic:

Does the scaled up 8.8 perform so well because the cap is relatively smaller?
If you mean at low thicknesses (3 - 4 in), then yes. Also, it has a sharp nose, as opposed to rounded tip of M82s body.
But these factors alone cannot explain the growing difference at higher striking velocities. It must be the result of deformation sustained by the US shell.

Yeah, that makes sense. The curves for the M82 start to flatten out and even curve the other way.
The US tree has been in this game for almost a decade now and we are still fighting the same issues since day 1. I understand balance and that not every vehicle gets every round they want but there is something internally wrong with how Gaijin ground devs implement US vehicles. The 90mm is just the most obvious and gets hit with all the inherent biases.

Well said, it’s also frustrating that Gaijin thinks that the gun is powerful enough that any enclosed tank with it is forced into 6.0 and above. The M4/T26 is the best example of the phenomenon which shares the same BR as the Jagdpanther, despite having a gun thats arguably worse than the Panther 75.

The 90mm should be as good or better than the Kwk42, but Gaijin continues to nerf it.
