Someone explain this to me please. I have read where 5" guns are sometimes referred to as being .38 caliber. Here is where my ignorance kicks in! When I think of .38 caliber, I think of the pistol. Correct me if I am wrong, but isn't a 5" round somewhat larger than a .38 pistol round?!!
O.K., all kidding aside, how does the .38 caliber designation relate to a 5" gun?
