I downloaded the current FAA Aviation Bill in the Senate. The only information on firearm and ammunition is listed in SEC. 731 Technical Correction, p.310; however, did a scan over the entire bill and nothing but FAA and aviation related. This bill is 336 pages long. I am looking at the ammendments, will post any findings!
This is what ammoland had:

Here is the aviation bill S. 223
Update: I did not find anything in any of the amendments listed to the bill, alot of discussion on Healthcare Reform Issues.
