Amen, brother!

A friend of mine bought me a slingshot once, not knowing that it is the sling that I am into.  It was suppose to be one of the best in the market at the time and it just does not perform nearly as good as the cheap piece of sling I had.

Hi.
Not shure I agre with you there.
Airgun World magasine had an article some years ago where they tested the slingshot.
They used cal 50 leadballs from Hornady and a Barnet slingshot.
The energy they mesured was a hefty180 ft.lb.

When I used the slingshot and some 16mm leadballs, I was able to shoot through a 12mm pineboard at 4 meters.
I dont know how much energy the leadball had, but it had plenty of punch.
I dont think the sling will give more than maybe 150 ft.lb.
If you use a staff sling the energy will likely be much more (I think )

Yeah, you can probably put more power behind a shot with a slingshot than with a sling, but the ammo you have to use with the slingshot is so small, its easily affected by wind and wind resistance and so, it's less likely to give you the range or punching power a 5 oz lead weight hurled from a moderately-sized sling is going to provide. I've got a slingshot and yeah, I've fired it before, but now it's pretty much resigned to sitting in a drawer whereas I was out for an hour with my slings today taking good sized chunks out of dead trees and slinging rocks through branches like they were paper.

It was 3/4" treated CDX plywood to be exact.  I was using 1" steel ball bearings and sometimes they'd go through the thinner plywood I used as a backstop as well!   I once did a video comparison demonstrating the accuracy and penetration results between a compound bow and the sling.

The arrows I used at the time would penetrate the plywood with about one foot or so showing out the backside.  There is no comparison between the kinetic energy output of a slingshot and a sling.

Considering that a 115grn. 9mm round travelling at 1200fps carries 368ft. lbs. at the muzzle.....

Let's compare..... 1" lead spheres weigh 4oz., That converts to 1750 grains, or over 15 times as heavy as a 9mm round.  Travelling at 250fps, the kinetic energy comes to a very respectable 243 foot lbs!

I'd say that Rebel's info seems a bit optimistic.  Considering that A 50cal. lead ball weighs about 180grns....that slingshot is required to have popped them out at a relatively blistering 671fps!  Now, unless that was truly one magic slingshot, (and the Barnett Diablo is pretty close) it's much more likely that their energy in foot lbs was closer to.....say.....36lbs.  


And that's being generously optimistic.


Given that the actual grain weight number is the same as Rebel's stated foot pounds, I'd guess that the grain weight figure might have been inadvertently substituted with foot pounds?


At any rate, Dork's right....the sling is king.


IF that king has seen what most would consider an overwhelming amount of practice!

A small piece of lead cube can be very lethal for slingshot ammo. I think a bigger piece can be used for slings....

Slingshots are fun....no doubt about it.
