It was odd when Imperial stopped selling ammunition. There wasn't any big announcement. They just stopped. In the 1980s and before, you used to see a lot of Imperial/Dominion/IVI ammunition on the US side of the border. It was probably guys coming into Canada that picked up some ammunition while they were here. I never did ask anyone who lived just over the border if there was any for sale in the stores there.
Steve, I lived just over the border…within sight of Brockville, ON. I think I bought the aforementioned Imperial ammo at The Sports Mart in Ogdensburg (right across The River from Prescott, ON.) I wouldn’t say it was everywhere, but it was not uncommon, especially in the less mainstream cartridges. Of course, the border was a lot friendlier place in those days.
To answer your question about whether I use the .22 HP anymore, I play with it. I make .22 HP brass from.30-30. I try different bullets. I haven’t done anything with it in several years.
