I don’t know nuthin about spreaders in Canada, but have to admit, I laugh every time I read your sig line...
I was going to say that if you reload, make up some old-style felt wads, not modern plastic shot cup wads. But then you'd have to look for felt wads and probably cardboard fillers, so your best bet might just be buying a box or two of old ammo from the early 70s or earlier.
