Howzit Ah Sook.
Yes, the Pauuilo "range" is still there and available; I've been there several times; last time was about 5 months ago. It is right off the highway, next to the Pauuilo Transfer station, and right off the Old Mamalahoa highway; so expect traffic in your background and right side periphery. It is small, with one mounted bench in between two trees; there isn't alot of room for multiple shooters though I always bring an extra shooting bench and table, just in case. I've lucked out and we were able to shoot without trying to shoehorn in with anyone else.
I'm guessing the length as I didn't measure it all the way...but I think it's only about 200-250 feet (65-85 yards at it's deepest point). We set up a bunch of pistol targets and a silhouette at 150 feet and had some fun. There are no burms, it looks mostly like a small landslide spot in a semicircular shapoe with the fairly high (20-25 feet?) back wall collecting all the bullets.
I'd say it is a gentlemans range; meaning bring alot of humility, a friendly smile and attitude, a sharp mind and good spirit. Oh, a couple trash bags and creature comforts...like losquito repellant. I don't police all the brass, just mine as I reload. I have picked up the plastic shotgun casings though, they really make the aina look messy. There isn't a lua so plan around that. First come first fire so I'd suggest going early; If someone is there ask how long they think they'll be, you never know.
I've shot at Manukaa (about the 83 mm out of Hilo. It's a haul...) you can go to either side. I don't shoot there anymore; as said, it is federal property, there are trails and ohana riding all kinds of off road vehicles. There are makeshift areas, again basically shooting intot he side of a rockslide spot so you and whomever your with should practice high situation awareness. It's much messier than Pauuilo, there is usually choke trash and we easily fill 3-4 55 gal bags. It gets hot, again bring your creature comforts. I've never been stopped and questioned, but that's a risk you need to assess.
