I made a comparative between 6” and 8” artillery caliber and their damage per minute.

Here is the graphic:

If you look close, you can notice that 6” gun is better than 8”. The reload time for 8” is 116.35% (same goes for 11”) and for the 6” gun is 83% or -17%.Reload for 8” is Extremely high compared to other calibers, for 16” gun is only 90% and for 14” is 95% less.

I checked it myself, I vaporized a BB North Carolina, and CL Brooklyn with my Myoko 6” configuration, but with a 8” almost I can deal some damage ( 90k-150k dmg, not much compared to 6”).

On other hand 8” has better accuracy, salvo speed and low angle than all above.

Post your experiences with 8" and 6" please.

P.S. Ignore the  last 3 in the pic.Is my DPM calculator made in excel.
