I declared my package as one containing ammuntion intentionally.
There seems to be a huge contingent on this site who seem to feel that whenever they run into a law which prevents them from exercising a perfectly reasonable course of action (like shipping a couple of boxes of ammo UPS Ground--I'd say that is a perfectly reasonable activity) that breaking the law as it is written is a viable option, because they don't think they're actually going to get caught, and pretend that therefore this is viable advice. It isn't. Perhaps you haven't noticed but there are HUGE penalties in place for shipping undeclared HAZMAT. And yes--preventing private individuals from shipping ammunition is absolutely a political objective of the gun-control left--but that doesn't mean that you can decide to just whimsically ignore the power of their regulations. They have the power to f*ck you--and hard. And that is something that they would LOVE to do--so the battle must be fought over making compliance a REASONABLE exercise.
Simply ignoring the regulations they are putting into place against you is a win for THEM.
