Thanks for the replies guys....
I asked because I recently picked up a new 12ga and the guy was spouting off about how it was federal law that the paperwork had to be done in blue ink.
Dicks Sporting Goods in Fresno, so go figure. Sad, but I expect that sort of thing there. The sales guy there says hes a gunsmith...surely has to be unlicensed if he goes about saying things like that.
