I believe last October update made AP shells give accuracy and damage bonus against heavily armored enemies and installations. Perhaps the bonus isn't as much as the Type 3 shells, but it is more versatile, since it also allows you to reliably bring down those pesky Rus and bosses that isn't installation, like Abyssal Nagano.
