Which of the old HYUD are you talking about? The "I wanna be WoT clone" or the "I'm actually an game made by Obsidian that isn't trying to blatantly copy wot"

Some further detail would be useful here AP and HEAT can easily fail if the target turns when you press the trigger and you either hit a stronger armor part or a era pack or grill. What tier, what vehicles, what ammo did you find more success. Just saying do this mission it's easy is not much of a guide.
