and I say thanks Nitrox! this is a handbook, you will see that everything turn around safety, safety and safety

its a first hand information about the whaling cannons used in the north atlantik. if you take a look into you will notice that shooting a whale is not so different from other animals. the only difference is the exploding harpoon head that kill a whael instantly if you hit him right.
the reloading stuff comes from kongsberg in norway but someone have a sizing die and a press to resize the 50 mm and 90 mm shells.
no doubt the 90 mm kongsberg whaling canon is the biggest hunting gun ever.
