Shot density is the name of the game.
Check video on the left for proof. I am a believer.

Shot density maybe great, but you also need PUNCH to tear up the boats that are used aginst actual shipping. this is why the MARINE CORPS & the AC-130’s use them. If the sob’s are sinking they are NO threat to you & your ship.
If you really loved me, you’d get me one for Christmas...
