Yes you have to pay hazmat. No I wouldn't do it for 1 jug. If you are picking up other powder and primers before they are sold out then it is worth it.
It's kinda like H4350 of which they had 7 jugs left, I grabbed one because I never know when they will have it again. I don't think we've reached peak stupid yet.
Once the free money goes out this will be like toilet paper at walmart. If there are supply chain disruptions how long until stuff is available. I'm not thinking about now, I'm thinking long term.
3rd Gen had CCI 450 small rifle magnum primers in stock so I grabbed some. http://store.thirdgenerationshootingsupply.com/
Things are starting to fly off the shelves so I'm topping off. I've heard that most powder is imported and repackaged here. Can't prove it but acting accordingly.
