1. Reload ammo for sale, you better have a license as a manufacturer. 2. Shoot other people's reloads? Only when I share DNA with that person. Shooting reloads from someone I don't know is no better an idea that using atoothbrush found on the sink in a public restroom.

3. Shipping ammo better be UPS GROUND, marked ORM-D, Cartridges, Small Arms. If you are looking for specimens of different cartridges for a collection, check auctionarms.com, under AMMO, FOR COLLECTING. The cost of shipping will make you weep. Be prepared to provide proof of age.
