H.R. 2710, "Lawful Purpose in Self Defense Act"

H.R. 2710, which is commonly referred to as the “Lawful Purpose in Self Defense Act,” would:

eliminate ATF’s authority to reclassify popular rifle ammunition as "armor piercing ammunition;
provide for the lawful importation of any non-National Firearms Act firearm or ammunition that may otherwise be lawfully possessed and sold within the United States;
protect shotguns, shotgun shells, and larger caliber rifles from arbitrary classification as “destructive devices” which under federal law subjects them to onerous registration and taxation provisions and creates a ban on possession of the firearm in some states;
broaden the temporary interstate transfer provision to allow temporary transfers for all lawful purposes rather than just for “sporting purposes.”
