An outfit in Quebec (I have had good luck with them) stocks these wads for the 16 bore. I have used the SG16 and it is a good wad. The other I have no experience with. I think they are both made for non tapered hulls i.e.: Federal or Euro. But at least they are 16 gauge wads in Canada.

That looks a lot like the Bp trap commander but I am not sure if they make it in 16ga
Going to have to look now

Yes sir they are both BP wads but they call that one the field commander
Strange for you to find BP wads in quebec. I thought Will B had BP locked down
The Bp specs
Commander 16ga wad (250/bag)
When loaded with 1-1/8 oz of nickel-plated shot, the Commander is truly a proven field performer. An easy-loading, compact wad great for both field and target. The shot capacity is just a bit larger than the standard 16-gauge wad as it is designed for longer ranges. Like the 12-gauge Z21 Trap Commander, the Z16 allows for a final nudge as the shell is closed, so loads are compressed for solid ignition. Designed for heavy 1-1/8 to 1-1/4oz loads, but it can be loaded down to 7/8oz by lightly seating the wad and using fillers.
