Weak deck Gun, 100 shells and still floating...

[Akula]

Hello

I just recently got back into SH3 with the Grey Wolves mod.

What a great mod it is too, but when I went through the training missions with the one where you have to sink 5 merchants with the deck gun, things didn't seem right.

I just simply couldn't sink any of them. I fired about 100 HE shells on one of them and still it just sits there floating.

Am I missing something?

Any advice much appreciated.

Thanks,
Gian
