Not that I do this but I have seen powder and primers shipped FedEx ground many times as just a regular item and no Hazmat fee paid. As long as it goes ground and there is no chance of it going up in an Airplane I see no fear of what is in the package, it's when the package is at 35,000' that they might want to know what's in it and they wont ship it that way anyway so just stick with anonymous ground packages and you'll be fine. I know a Police Sergeant that received 5lbs of Varget and 5K CCI BR2 primers this way a few times with no problem at all. Just an observation of mine if you know what I mean.
