Prob part of shipping delays, part due to embargo of Russian goods, someone has to 'be the importer' - don't know who is 'the' importer in Canada, US Barnaul is in Ohio, USA. There are a few calibers available at various Canadian on-line sites but not all in one place that I can see. And when you add shipping ... the cost gets up near US ammo. Add competition with Chinese manf as another 'part'. I've got a few boxes of B left, saving them while I shoot up the Chinese.
