Most places sell the same slingshot...has wrist support and the elastic part looks like surgical tubing. They work well. We’ve never ‘shot to kill’ with it; but, we have found large automobile wheel bearings make great ammo.
Problem is, hitting the damn things, especially if moving. I spent many hours with one as a kid, and best I could do was maybe within 6". Would not want to count on one to stay fed.
Wrist-rockets will definitely kill small game. Killed a grouse with one once, had a nice meal while backpacking.
Get a suppressor for the 22.
They work fine but the rubber tubing pieces rot quickly.
This is a fun wrist rocket. Sold at Dicks or Bass Pro shop for about $8.00.
I use 1/4 inch steel shot usually sold in the same isle. $5.00 for 100.
Instead of using a wrist rocket, snares are much better for small game. Even so, you might catch one animal or bird for every 20 snares you set up. And then, likely only in season.
This is a big motivator to raise your own domesticated food animals, and why there are chickens all over the world.
Wrist rocket shooting an arrow. It’s call a “slingshot arrow” very effective against small game if you have any stalking skills.
I haven't used such things since I was a kid. I don't think you can easily take small game with that. There are tons of problems with this thing, but to name just two, its energy is miniscule, and stability of the projectile is nonexistent.
As others already indicated, get an air rifle and/or an air pistol (both break barrel) and two pounds of ammo. Those little projectiles will be pointed, and they will fly the pointy end first, entering the game. Hunting pellets expand, they have some decent energy and they drop a small game (like a squirrel) within 25-30 yards well enough. The barrel has rifling, so the pellets will be spin-stabilized. Air rifles usually produce negligible noise, but some - like Gamo Whisper - come with integrated silencers. I have one, and it is pretty good. The rifle that I have is equipped with a scope (it was part of the kit) and it works pretty well. If you are hungry in the forest, with such a rifle you will have something to eat within minutes. Note also that it will shoot upward, at the bird in a tree, with the same efficiency; pellet drop is small and it's easy to compensate. Outside of cheap low-tech pellets, no ammo is required. This is a pretty useful survival tool.
Finally, here is one more reason to avoid low accuracy weapons. You always want to be reasonably sure what you are about to hit. Primitive weapons require a lot of training; archery, it is said, is an art that one has to study his whole life - and a bow is nearly a point and click weapon, compared to a slingshot. Problem #1 is that you miss your dinner. Problem #2 is that you hit what you shouldn't be hitting. Modern weapons give you far better control over the placement of the shot.
I see you’re in Hawaii? If you haven’t already, check the law—In my state slingshots and wrist rockets are illegal, along with crossbows and throwing axes.
Good for chucking rocks at f e m a troops?
I recommend a 22 air rifle. Not a springer.
I have a crossman Nitro Venom Dusk or some such thing. Maybe $150 with scope from Wal Mart.
Trigger was awful, pulled it out & honed everything, now it is just bad, but liveable....
Squirrels out to 30 steps are clean one shot kills, every time. I admit I’m going deaf, but it is not loud.
Use the heaviest pellets that will group. Expect to run 250-300 shots to get it to settle in.
Spend the $8 and get a slingshot. They are fun and easy to use. Spare rubbers are plentiful, or buy surgical tubing in large rolls. When I was a kid I got a couple of gallons of marbles at a yard sale and killed many squirrels with a wrist rocket.
If your model folds, you will carry it with you more. They are also easy to make and check out some of the flat band models people are making, using medical rehab material of various strengths for the rubbers.
So what if it takes practice. Few skills don’t.
Won’t penetrate a blue helmet, will it?
