Just a bunch of #######s who bulk buy and resell at double the price or more on sites like ###########
Apparently individuals can import small arms ammo into Canada without a import permit as long as it’s under 5000 rounds and for personal use not resale (reselling would require an import license)
You are right about lots of 50AE & 500 s&w ammo in the US if interested i can supply you a large quantity of ammo and have it shipped to Canada, but you are looking at about 25 boxes +50AE to make it worthwhile so you would have to resale on the site but that is not a lot if you are shooting a box a week so think about a bulk purchase and you are correct about max. quantity of 5000 rounds at once "FOR YOUR OWN USE" but that is a large amount of cash to lay out i also have Hornady bullets & 1s fired brass as i don't shoot 50AE anymore, but i do shoot 500 s&w now and then
