They are made in Ste-Justine-de-Newton, Qc. Canada (from box label). In .410 do not have a shot cup. As a result although they shoot fine, in my .410 it is a bit of a lead mining operation to clean the barrels properly after use. I believe the other gauges do have a traditional shot cup that holds most if not all the shot.Just about nay hull can be reloaded at least a few times. Where are they made? That should give you a hint as to whose hulls they are.
