No postal for assembled ammo, powder or primer.
I did have them deliver a couple thousand 230gn bullets from Missouri Bullet co, (Dont think the carrier liked me that day

), and then two days later a couple thousand 45 auto cases came off of gunbroker. Having seen the companies they were shipped from, plus delivering my handloader mag, two NRA mags and a bunch of Cabelas/Midwayusa shooting catalogs, when she heard the cases clinking in the box, she told my wife, "You know it's illegal to ship ammo through us, right?". My wife told her it was just stuff to reload and not the put together stuff.
