How long will it be before an executive order will be signed banning the shipping of ammo and or guns?
The fun has only begun.

Soon for sure ,,,,,,,

Disadvantaging interstate trade in lawful goods is prohibited by several previous Supreme Court rulings.

Sounds like packing the Supreme Court will fix that. I have a question, why can't you ship ammo through USPS then?

You would trust them with packages that go boom?

Prohibited Items Developed by the USPS elites....
These are items you can’t ship with USPS—no exceptions! You’ll notice that all prohibited domestic items are also prohibited to be shipped internationally. However, some items (like aerosols and dry ice) are only prohibited internationally and not domestically.

Prohibited Domestic Items
Air bags
Alcoholic Beverages
Ammunition
Explosives
Gasoline
Marijuana (medical or otherwise

Heck, I can't even find any ammo to ship.

I seem to remember Biden saying he would put an end to internet sales of firearms. I would assume that would mean private and business sales... one back door way to practically stop shipment of firearms?
