which ammo to saw off wings and blow up fighters

[David198502]

hey guys.i wonder which ammo i should use in my bf, to saw off wings and get spits and hurries to explode.with my current bullets, i only make a lot of wholes into them.sometimes they begin to smoke.most of the times i think i kill the pilots.when i shoot at beaufighters,they mostly catch up fire near the engines.but spits and hurries just look like swiss cheese after i shot all my ammo at them.i played now 60hours this game but only managed once to detach a wing from a hurrie and i think twice to explode a beaufighter.what are your experiences?
