What's the law read for Canadians to purchase shotgun shells in the USA to take back to Canada? I know we can take 10 boxes to Canada, when we go waterfowl hunting in AB or SK. There is a local store that sells the RST ammo, last time I checked, and if close to the US border, perhaps on a trip down sometime, pick some up, if it's this area. I think on the RST website it says who the vendors are for their product, so if you're closer to WA State there may be some RST vendors in the Okanagan Valley.
I see BC and AB license plates here all the time, shopping in CDA.
