I watched a 'merican YouTube video review of a rubber band powered 'rifle'. Well it has a shoulder stock, foregrip & trigger, and what else are you going to call it? - I went on AliExpress to see what they had, and when I found one - I bought it. (nz$241.82 inc GST)

"A more dramatic effect on the ballistic dummy than a .22 LR."
'Ballistic Skulls' cost around US$150 - $300+ each
I calculate power at around 6.75 foot pounds of energy with a 32 grain 8mm s.s ball..
A 8mm lead ball weighs 46grain +-
This is around HALF the energy delivery of a quality Air Rifle
- a longbow ranges from 30 ft-lbs to 90 ft-lbs - A 40 grain .22 LR round 80 ft-lbs
Energy calculations are very velocity influenced. - if you doubled that 300ft per sec to 600ft-per-sec you'd almost quadruple the energy figure to 25.6 ft/lbs. (Double the mass and that only doubles the energy)..
However, an 8mm steel ball at 300 foot per second velocity is going 200 mph. - I don't want to be hit by anything that solid at 200mph ..
Now, this 'toy' will do damage by lethal blunt force trauma. Some testing reviews of black powder 'Turn-off-Barrel' Percussion Pocket Pistols with small powder chambers find velocities around 300-400 fps .. they did the job at contact ranges.
- I don't know how to correlate energy level with effective damage or 'knockdown power' or "killing power" for these impact/penetrations at lower velocities. How do you, for example, measure the effective power of a small sharp-pointed low-mass steel dart that penetrates from an air weapon?
Some folk say that an ancient Roman lead slingshot "is as powerful as a Forty-Four-Magnum" - well that's nonsense, but when a low energy weapon kills, would the target be MORE dead from an even heavier blow?

AI says: Muscle-powered weapons are tools that use human muscular energy for propulsion, and they can be categorized into direct-contact and projectile types. Examples include swords, axes, and knives for close combat, and bows, slings, and spears, which have been used throughout history.
Enhanced Version Slingshot Hunting Powerful Catapult Mechanical Slingshot Rifle Portable Stretch Outdoor Distance Shooting Toy 7 sold. (8 now) - I'm always up for a laugh eh ..
Thinking ahead a bit - I also searched AliExpress for steel balls to use as ammo, and ordered 200x 8mm s.s balls (nz$38.14) = 20 cents each but reusable if you catch them ..
Nine days after ordering, the first small square package from Wang Peng, China landed on my doorstep - discreetly labelled as "Bicycle Parts".
The first bits of a new adventure-puzzle - Unwrapped ..
The Third Package ..
I'm not showing the yards of 'Clingwrap' that was wound around all these parts or the securely taped plastic 'bubblewrap', that was all a right pain in the butt to strip off .. Nor am I showing the instruction sheets for assembly - as there were NO instructions.
PENETRATION of the first 8mm steel ball was about 34mm - I located my old test image from 2021 of a Winchester 555 .22 LR that penetrated around 70mm after nicely expanding to 11mm.
46grain lead versus 32gn steel. Same Size.
Never mind eh .. I can do this.
This links to a short assembly-guide video for Falcon GT slingshot:
Putting it together was easy, except neither of the two spare scope-sights I have is suitable so I've gone sightless in this pic ..
The Tranter .44" is there for scale. This Falcon Hunting Slingshot is all CNC machined metal apart from the elastics - and very well made for a "toy".
The new Red/Green Dot sight with side-mounted Laser was affordable @ nz$36.50 - but it was a bit slow to arrive from China, taking 17 days to my front door.
AliExpress deserve a brief plug following more successful deliveries all the way down here to NZ .. in that mostly I have had great service and good value - of multiple purchases from China over recent years - only one item went missing and one wasn't what I thought I had ordered .. out of 100's of purchases of clothing, tools, appliances, watches, and all sorts of stuff. - THEY ARE GOOD.
Right - DOWN TO BUSINESS ..
I "fired" the slingshot into my old red Ballistic Plasticine modeling clay, with the least powerful 'two-tubes' rubber and was truly impressed ..
My second penetration test made a wound channel of 40mm long. -There is zero scientific basis to equate these results .. but the slingshot ball with a tenth of the kinetic energy of a two-two appears to demonsrate more than half of that .22" penetration.
My guess is that equates to penetration in ballistic gel of around three to four inches plus ..
Do not shoot this slingshot at anything you do not want to destroy.

- Might a heavier lead projectile be more 'powerful'? - Take a look at this .. The shiny steel 8mm ball penetrated 5mm less than a 32cal (8mm) lead ball.
This Wang Peng Slingshot is great - it works - is accurate - is quiet - is fun - and is plenty powerful. - what more could you ask for? - Got a possum issue?
The new 850 kW Porsche Cayenne E car-toy costs more than $220,000 .. this is cheap fun for a 1,000 times less - I like WangPeng outside in the garden ..
Life is great,
