I sent mine in today. I consider myself lucky to have only recently investigated this option.
For me I just dl'd the form, wrote a check, and sent 2 return receipt letters.
I'm crossing my fingers.
I'm on the fence about the C&R + COE combo.
Not sure it's worth it.
The 10 day waiting is a pain but ifit saves me a hundred bucks it's not that much of a pain.
I thought I read someone hinting about ammunition exemptions too? and more than 1 in 30.
Is there a source for this?
