The HESH is quite decent ammunition on the T58, unlike most of the other tanks, thanks to the 2.6-second reload, which compensates for the unreliability of the HESH. Just shoot under the bottom of the tank, or the lower half of the enemy's side armor, so it one-shot much more often.

The tank has the same reverse and forward speed - frequently it might be better to drive towards the enemy with the back-first to increase overall survivability.

Move the scope to 100 meters from the beginning of the battle, since the first 100 meters of the projectile has a very flat trajectory, this will make it easier to aim both in close combat and at medium range.
