My Experience almost exactly. I was a 01 FFL out of my home for maybe 18-20 years. All I had to do was complete the application and send in $30. While a dealer, I didn't sell much, maybe 12 to 15 guns a year, but I was able to get my supplies pretty cheap. I never had any face to face contact with an ATF agent until I had to give up my license due to the Crime Bill passed by Clinton. The authority to regulate home businesses fell to the local authorities. My local authority (Dearborn) said no home businesses of ANY kind. My business required a Federal license, so I was forced to surrender it. I never did anything that wasn't completely legal. Conversely, a local gun shop owner sold a .25 ACP to a high school student with no paperwork at all, the student was caught and ratted him out, and the dealer never had to surrender his storefront FFL. Interesting...
