Called Brownells about their "additional requirements" for states like NY, IL, CA, CT, DC ... for sales for ammo.
Interstate commerce is covered exclusively by US Congress and they passed 18 USC 922 regarding sale of guns and ammo.
18 USC 922 incorporates firearms laws of states and ammo laws for only armor piercing ammo of the states into the federal section.
Brownells does not sell armor piercing ammo so their policy is moot on that point.
For interstate sales of regular ammo congress decided not to incorporate state/local laws into this section.
Retailers are also protected under federal law from lawsuits too.
So I asked Brownell about why they require "further requirements".
Like on this product:
At first the company said that they were following the law. When 18 USC 922 was discussed and how state laws of other states don't apply to them regarding ammo then they said that it was for their customer's benefit to insure that they don't run afoul of local laws.
Brownell's brought up CT law, CGS Sec. 29-38M(c) that states, in part:
(c) On and after October 1, 2013, no person, firm or corporation shall sell ammunition or an ammunition magazine to any person unless such person holds a valid permit
The limitation is not upon the BUYER but the seller and only to sellers in the state. So it was explained that a person in CT could buy ammo w/o fear of penalty, even within the state. The law is meant to regulate intrastate commerce and not interstate commerce (which a state cannot do anyway).
Brownell's is re-evaluating their ammo selling policies and a decision by next week is expected.
