The square cube law as is relates to mass and weight means that over 20in./50.cm becomes very difficult to operate as a swivel gun.

Sorry for my confusion Hellery but, your vision of typologies doesn't fit into what i humbly understand of these things, namely on what concerns swivel guns. Where would i place in it, for example, barrels of XV-XVI century Portuguese berços, with a length of 162 cms. (weighing 100 Kilos) or 118 cms. long Malasian lantakas ?
I take it for me that, as long as the trunnions are accurately positioned, which is to expect from the gun smithing specialists, "heavy" cannons swivel so easily that their weight doesn't count.
... Unless i am in a different frequency and didn't get your point, for which i would appologize .
