Just wondering, would like to just shoot air rifles and pistols. Really don't want to trek to H.K. just for air powered stuff.

It's against the law to:

- Carry an air gun on any street or public parcel, unless it’s in a carrying case;
- Discharge an air gun from any street or public parcel;
- Discharge an air gun in a way that endangers people or property;

Other than that, as long as you're on your own property or have permission from the owner, and you make sure the pellets or BBs don't travel outside that property, you can practice pretty much anywhere.

Other than that, as long as you're on your own property or have permission from the owner, and you make sure the pellets or BBs don't travel outside that property, you can practice pretty much anywhere.

Not oahu, BI, but I shoot rifle and pistol in my back yard for practice all the time.   One old crone neighbor apparently called the cops who told her it was quite legal if kept on my property.

I shoot from my driveway into my garage all the time and used to shoot in my Mom’s backyard.
My neighbors are cool though. But nothing illegal.
Just keep pellets on property. I don’t recommend bb’s due to ricochet.

There are targets where the backstop is angled and you can actually shoot indoor and it will catch the pellets
 

Used to do that all the time in backyard (growing up).  A soda box and newspaper makes a great bulletstop.  But, who has newspaper these days. . .

A soda box and newspaper makes a great bulletstop.  But, who has newspaper these days. . .

Made a wood pellet stop with grooves to slide cardboard into and tack on targets.  Ripoff of a design I saw for sale on Amazon.  Cardboard needs replacing fairly often.

Blocks of plumbing duct seal for capturing pellets.   Peal out pellets and replace as needed.  Whack of the pellet hitting cardboard is the only sound.

Let's assume OP or someone else doesn't have a yard or private property to shoot.

Besides Koko Head (or maybe even the private indoor gun ranges), where can one go to shoot air rifles?

I do have a yard with a lot of chickens, that tear up my yard and crap everywhere.  Both my neighbors to the left and right of me feed them. The wife can't stand them. I have a couple of airguns I can use, but the ones I really want to shoot are not backyard friendly. If I remember correctly I wouldn't be able to air up near the benches? I would have to go down to the parking lot. Put it this way, the last time I went to Kokohead, you could shoot at the gong deep in the valley and set up 200 yd targets.

When I was at the range a couple of weeks ago, a guy was shooting an air rifle on the bench next to me. He had his tank in a crate next to the bench and was (or appeared to) fill up every so often. Cool guy and was talking story with him between relays.

Best to check with the ROs one day.

Ask friends that also like airsoft if you can come to their property to shoot?

If you want to just practice for the benefits that translate to firearms practice, where you practice isn't a big deal.

But, if you're looking for more people to shoot with and maybe go to events and competitions, maybe contact the local high schools.

There are also commercial options:

That's just a few.  All depends on what the OP's objectives and desires are.  I also saw a link for Kualoa Ranch -- Private games at $10 per player.

Let's just say, it can be just as irritating as the fireworks we hear going off randomly.

My sister and BIL live in the Nuuanu area and they mentioned chickens getting bad.  I was telling her to shoot them with airsoft, at the level they don't hurt the chickens.  In that context, not backyard friendly means that the "bad" chickens are in the neighbor's backyard and that neighbor are more sympathetic to the chickens. . .  so basically no can shoot um. . .

To be clear, these are NOT airsoft type, green gas, paintball guns....ect.  These are capable if pushing a 34gr. Slug over 1000fps.

Would have been a good thing to include in the first post rather than this:
"Just wondering, would like to just shoot air rifles and pistols. Really don't want to trek to H.K. just for air powered stuff."

You say they are capable of that velocity, but can they not be adjusted to a more "backyard friendly" setting?

Box full of newspaper will still stop it.
Let me know if you need newspaper. Can back it with plywood if need.
.34 gr. Slug. .22LR is pushing pushing 40 gr at 1150 FPS.
Shot a .22LR into a box of newspaper and a plywood backing just in case. Box of newspaper stopped it.

Can you make a homemade suppressor for an air gun legally ?
Didn’t see anything in the H.R.S. Prohibiting it.
Commercial air guns come with built in suppressors.
The .22 caliber break barrel I had with built in suppressor barrel was quieter than my Benjamin pump.

I am not a lawyer.

I have ones that are backyard friendly. It's the ones that are not I'd like to shoot more often. These can't be adjusted down.
