My C&R license arrived the other day. I know I have to record qualifying firearms that I use the license to acquire in a bound book, but is there any reason I should (or shouldn't) transfer the C&R guns I bought previously via normal retail channels into my C&R book? I think the procedure would be to record them as "transferred from my private collection" and the day I made the transfer as the acquisition date, but I'm wondering if there would be any benefit to doing so. Any thoughts and advice are appreciated.
