backstep11,
My first question to you would be - "what are your interests" ?
Check the ATF web site for a partial list of guns you could buy, and remember that any gun 50 or more years old is also C&R.
There are so many guns that qualify that the list is mind boggling.
Keep in mind that a C&R license, when buying/selling guns, is only useful for out of state deals, and in-state deals when shipping is required.
For face-to-face, your C&R license is of no value, and my experience is most FFL's don't even want to know about it. Again, I mean for FTF deals.
And yes, there are some firms who will offer a discount to you for supplies, etc., but that is a courtesy, and is not the reason ATF issues C&R licenses.
Good luck, I hope you find some great deals.
