I would guess Hodgdon, at least for now, doesn't want to get tangled in MA laws which restrict ammo. Oh, and ammo includes:
"cartridges or cartridge cases, primers (igniter), bullets or propellant powder designed for use in any firearm, rifle or shotgun"
There are sever limits as to the quantity of "ammo" you can possess. With out a special storage permit, you're limited to:
- Not more than 10,000 rounds of rimfire ammunition
- Not more than 10,000 rounds of centerfire rifle/pistol ammunition
- Not more than 5,000 rounds of shotgun ammunition
- Not more than 9999 primers
- Up to (but less than) 16 pounds of smokeless powder
- Up to (but less than) 2 pounds of black powder
I'd need the permit. Even then you're limited to to a total of 100,000 rounds.
Do you have a source for these numbers that you can cite? Somewhere that says they are a legal LIMIT, and not merely a RECOMMENDATION? I have seen this posted an awful lot, but been unable to find these numbers anywhere. As far as I am aware, these are merely recommendations, and, even then, some of your numbers are very wrong.
"11-3.7 Smokeless propellants intended for personal use in quantities
not exceeding 20 lb. (9.1 kg) shall be permitted to be stored in original
containers in residences. Quantities exceeding 20 lb. (9.1 kg), but not
exceeding 50 lb. (22.7 kg), shall be permitted to be stored in residences
where kept in a wooden box or cabinet having walls of at least
1 in. (25.4 mm) nominal thickness."

What is posted above is the National Fire Protection Association code, NOT a hardline law. In fact, you will see a great deal of stores in clear violation of it, as it clearly states:
"11-3.8 Not more than 20 lb. (9.1 kg) of smokeless propellants, in containers of a 1 lb. (0.45 kg) maximum capacity shall be displayed in commercial establishments."
Please, if you have a state or federal law that applies to this, I would like you to cite it.
