As far as I know there are no bullet mould manufacturers in Canada and if you want a custom mould check with Mountain Molds, you can design your own bullet using his web site, I have 3 of his moulds for my 500 S&W, 400, 440 and 500 grain for casting gas checked bullets and they are excellent as is his service. The lead time is currently 6-10 weeks according to his site as these are custom made moulds according to your specs. With his program you can see the changes you make to the design of the bullet in the bottom left hand corner of the design page. I bought a Lee 440 grain mould and in my opinion it is a total POS, the block is way too small for the size of bullet cast so it heats up too fast and mine won't cast a round bullet as it is impossible to get the two blocks to line up properly, just pure junk.
