Aloha!

I am new to this forum and new to firearms would be happy to learn a bit more about firearms in general.
Anyways I was wondering the laws about owning a black powder/loose powder gun and if you need to be 21 years old in order to buy one online and own one it legally?
Also if I need a permit to get the components aka the powder, percussion caps,etc? Mahalo for your guys time and I hope to learn more about firearms in the future!

You can't buy black powder here.
You can buy a synthetic  which is Nitrocellulose.
It goes bad over time.
You can buy the materials and make your own real black
powder,  I'm planing on doing that now.
Making my charcoal from Koa is the hard part.
As far as I know you don't have to register or ask permission
to purchase a black powder gun.
I don't know where you can locally get caps,
but there is always a way.
Youtube tells you how to make them.
A Colt Dragoon can get someones attention.

No registration is required, but you still need a permit to acquire.  If it's been converted to use centerfire cartridges, it needs to be registered.

If you bought the gun outside of Hawaii and are just moving here with it, then it's yours to bring -- no registration or permit needed.

§134-2  Permits to acquire.

(a) No person shall acquire the ownership of a firearm, whether usable or unusable, serviceable or unserviceable, modern or antique, registered under prior law or by a prior owner or unregistered, either by purchase, gift, inheritance, bequest, or in any other manner, whether procured in the State or imported by mail, express, freight, or otherwise, until the person has first procured from the chief of police of the county of the person's place of business or, if there is no place of business, the person's residence or, if there is neither place of business nor residence, the person's place of sojourn, a permit to acquire the ownership of a firearm as prescribed in this section.  When title to any firearm is acquired by inheritance or bequest, the foregoing permit shall be obtained before taking possession of a firearm; provided that upon presentation of a copy of the death certificate of the owner making the bequest, any heir or legatee may transfer the inherited or bequested firearm directly to a dealer licensed under section 134-31 or licensed by the United States Department of Justice without complying with the requirements of this section.

§134-3  Registration, mandatory, exceptions.

:
(d)  Registration shall not be required for:

 (1)  Any device that is designed to fire loose black powder or that is a firearm manufactured before 1899;

So I need to get a permit in order to buy a BP gun and I need to be 21 years old in order to get a permit? Also thank you for the quick reply.

That's pretty much how I understand it.

Mahalos for the help!

Just don't get that 50 cal BP one with the suppressor on it.  When they first came out, they advertised "50 state legal".
