I got a call from one of the general managers at the Cabelas store here in town... I must confess that I've pulled a brain fart on his name, but it was about 1/2 an hour ago.
He confirmed that it was absolute smoke being blown by one of his staff. He was very interested in the particular clerk's name, which I also confess to not making a note of in my frustration from the initial encounter. I'm bad with names.
Cabelas does NOT fax their 4473's to the FBI. The purpose of the phone number is in the case of errors on the form, or in the event of a 3-day hold order from NICS.
He is going to educate his folks exactly in regards to workflow of 4473's as well as agencies that have lawful access to the forms.
