There are ways to do it legally, but after the export fees and Duty at border financially it hasn't made sense. {Canadian side of border doesn't care, it's leaving the US that's the issue.}That's changed now because primers are so expensive on the open market. But like most folks, I buy them when I see them. Powder isn't great either, about $100 a pound, more in private sales. And you don't get to pick a powder for your rifle, you get to pick what's on a shelf lol. The committed shooters bought when we saw things going bad, and continue to do so. In my life what I've seen is, once the shelves in the US get stocked pretty decent, 4-5 years later we see some product numbers improving up North here.
