You have to have hazmat certification to ship ammo via FedEx. UPS is the only outlet you can use without one. You just have to mark the box with the correct ORMD labels and take the package to a hub, not a ups store or authorized shipping agent.
This is wrong. You can ship via Fedex ground to the lower 48. You will need a hazmat cert to ship air to AK or HI. I have shipped and received alot of ammo via Fedex ground. To ship, you cannot drop it off at a Fedex store, you must either have an account and have them pick it up at your house or drop off at the fedex hub in your area. Add ORM-D labels to the box and make sure it is sealed up. They are usually cheaper to ship than UPS too.
