Why is this even still an argument, even if the M1 had M833 it would be such a minor upgrade it wouldn’t even change anything besides the fact that penetration is now less inconsistent and the sorta fix the low spalling(though this can still be stuck in with the previous statement)
The round is just bad and even things at much lower BRs have better rounds than it such as the T-62M1, Leopard 1A1/5, Radkampfwagen, Leopard 2K, AMX-40 and this keeps going.
in a vacuum of nothing but statistics it looks perfectly fine, the gun might be mediocre but the mobility is amazing and the armor is decent.
But the problem comes in when you bring up the fact it’s war thunder and a real 3D environment, the round it has may usually be able to pen a T-72 turms from the side but the round is bad enough that the contact one on the side can eat the whole thing if you’re unlucky, it’s also 105 when nearly every other MBT has a 120 which in game has (seemingly) twice the spall(combining damage and fragment amount)
In the Leopard 2A4 shooting another 2A4 in the hull often does tons of damage or kills them outright, but in my experience in the M1 with M774 it either kills 1 guy, doesn’t pen or kills 2 and the engine, you could argue a skill issue here but at 10.7 and above you really don’t have time to aim very well most of the time and it’s usually who ever clicks first wins, but not when you click first and the round kills one guy and looses enough power to not kill the second.
M833 isn’t some god round that’ll literally make the M1 the best tank in the game, but what it will do is make it less infuriating to play at times.
(You basically have no chance against stuff like the T-80UD and M833 isn’t going though that thing either)
