Well, I don't know if this is the best way to ship, but it's certainly the most expensive. For long guns, USPS is the most economical and, IME, is as good as any of the ground shipment alternatives. Just be sure to pack it well (I find a sturdy cardboard box with a good cushion of bubble wrap) works well. You can't ship handguns via USPS, BTW--these must go UPS or FedEx overnight air. Very expensive. You're probably better off to get an FFL holder to ship handguns for you. They can ship USPS, we peons can't. BTW--don't tell the shipper the box contains machine parts or anything like that. You gotta tell them it's a firearm. With USPS, failing to do so violates federal law. I don't know what UPS or FedEx can do to you. So far as I know, this is, for them, a matter of company policy.bdale said:I've been told to ship next day if using UPS this assures it gets preferred treatment, and every move documented.
