Can I legally make my own black powder in Hawai’i?  Process looks easy, needed compounds seem easy enough to get.   All feedback welcome.

I follow the Don't ask,  Don't tell philosophy in da land of Hawaii, currently being run by people with Communist inclinations.

Based on this reading of an ATF response to the question, you can make it for your own use, but you need a license to transport it -- even if only taking it from your home to the range.

I know C&C of Honolulu Ordinances have rules about storing explosives, such as fireworks and other explosives.  You'll need to stay within the amounts allowed for safe storage and fire ordinance compliance.

DIY Black Powder Legal? A lot of people won't like the answer!

Thanks for the responses.  I’ll have to talk to some muzzleloading enthusiast here in Hawaii when the range opens and get schooled on how they work with this.  I am actively searching for a Flintlock rifle and pistol and I have been reading that Pyrodex is not gonna work very well for that. 

the gun show is in a month
you should be able to find some people there to talk to...

I was kinda thinking about getting into black powder as well. It’s so easy to go to the range and waste a bunch of ammo. Slowing things down could be a lot of fun.

per RSN
never ask for permission.
be vey careful.
shit can blow up on you.
just need pure sulfur (Pharmacy supply) tree stump remover(Home depot) and charcoal.make your own or buy at the store
mixer well away from home.
making FFG or FFFG is an acquired skill.
 

I tried when I was about 10 years old. Mine didn't work too well.

now you tell me.....50 years too late

i've mentioned before a series on the The Blaze network called Independence USA about a family that moved to a remote farm and started a bunch of projects to learn how to live off the grid should there come a day when society starts to break down.

One episode included making a firearm and the powder plus the musket balls needed.  I think they used a factory-produced firearm to test the powder, but they did make a firearm as well (the father had a blacksmith setup where he was able to forge all sorts of useful things).

I think the result was, although they could make powder in a pinch, it made much more sense to buy it and store it.  Consistency and availability of quality components was a concern.  A blackpowder rifle is great for hunting, so you aren't using that much powder over time.  But for self defense, trying to reload another shot isn't practical.  So, they built a reinforced basement storage room for all the firearms, ammo and ammo components for reloading cartridges and blackpowder loads.

it all depends on your intended purpose/anticipated needs.  If it's just for research and education, maybe transport the components to the range and combine them there?  Not blackpowder nor an explosive until then.   

No discussion about black powder would be complete without mentioning Captain Kirk and the diamond cannon vs. The Gorn.

trivia: the voice of the Gorn was Ted Cassidy from the Adams Family (Lurch)

i'm sure the poster previously known as "darmok and jelad at tenagra" is fully aware of that episode

Violations don't always result in enforcement.

Mixing it up dry in a ball mill (glass jar with a shaft on the lid plus marbles) works OK for experimental amounts, and it will go bang if it's confined.  But it just fIzzes when burned in the open.

"Corning" is the process of dampening the mixture so that the KNO₃ dissolves slightly and thoroughly and intimately coats every tiny particle of charcoal and sulphur,  After it's dry, you can break it into suitable granules, and this "corned" powder is what goes FOOM in the open.

I leave the legalities to the law types and the knowledgeable BP  shooters.

I leave the problem of scaling up from the glass jar and marbles setup to the individual's engineering skills.

Do not use or have nearby any steel or iron tools or anything around when messing with BP.  Commercial powder MFRs had special bronze and brass implements where needed.  Also be Aware of static.
