I have shipped reloads to my buddy in Colorado through the USPS. I told the clerk it was ammo and he said OK. No joke. It got to Colo Springs A-OK in three days.
eford, I didn't think it was possible to ship ammo via USPS so I looked on line and found this:
Can ammunition be shipped USPS? No, you are not allowed to ship ammo via the United States Postal Service.Jul 9, 2020
USPS prohibits the shipment of ammo both domestically and internationally. Therefore, you'll need to use another carrier such as UPS or FedEx if you wish to ship ammunition.
