Question conerning geck gun attacks

[John W. Hamm]

From time to time I read that some parts of ships are not as well protected and by placing a well aimed shot depending on the type of ship, you can sink them with ease, I use the newest verion of RFB.

The issue is I attacked a medium old freighter I had only 1 torpedo left so I took aim and hit at the rear of the ship near the prop, she took on a bit of water and isted according, and she even slowed a souple of knots.

So I was forced to surface and whip out the old deck gun I more than likely put about 82 shots (all I had left) all in the same place (waterline rear right by the propellers) and would you believe I didn't even put a dent in it !!! not one scratch hell I bet it didn't even bend a screw. needless to say no speed was ever lost. I just thought I might mention this
