I'm familiar with HR45. However, I have not seen bills for (2--ammo accountability), (3--expanded AWB) and (4--Expanded "Lautenbach" amendment). Do you have these available?
Google Ammunition Accountability. They have bills pending in many states now, and are currently lobbying for a federal bill which many Dim congresscritters back. Microstamping has been talked about by the Brady Bunch.
The new AWB as described here is backed by Feinstein, Pelosi, Bloomberg, et all
Lautenbach amendment upgrades would be part of the licensing requirement
The licensing requirement comes from HR45. The insurance requirement was a bill tested in IL by one of Obama’s former colleges (Trial balloon for a Federal law)
