32 ga ???

Jerry, do you know why the cartridge manufacturers referred to the .410 as 36ga? (a sample as shown in Dave's post)

Edgar,

This is only an educated guess but the base diameter of the cartridge/shell is 11.9 mm/.490, so they opted to call it in addition to a .410 a 12mm which is close to a 36 gauge (but should have at least called it a 40 gauge), ignoring that the bore size was actually 67 gauge. I guess 36 gauge sounded sexier than a 67 gauge and would result in more sales.

I thought the 410 was considered more as a caliber than a gauge.

Yup, it's not a 410 bore (though 410 bore is closer) and it's not a 410 gauge either - technically, it's a .410 caliber shotshell/shotgun.
