With the right ammo: sling vs 9mm pistol = a tie.
Jul 9th, 2009 at 11:55am
 
Ive put a hole into a cinder block wall at an abandoned factory with my short sling. The ammo I used was a 7 oz screw that happend to have the end pointed at the wall (The screw was not pointed), so it made a perfect circle. I hope to post a pic or vid of it soon. We will be doing more tests with 5-6 oz lead balls that we are going to make. Ive read online that a 9mm handgun can penetrate the first side of cinderblock and bounce off the second. And other tests were done with a 9mm and a 45. heres a qoute: "In a self defense video I saw, they fired a 9mm and a .45 at a cinder block. Two shots each in the same spot. Both cratered the block ont he first shot, penetrated the first side of the block on the second shot, but neither went through the block." And here's the site http://www.greenspun.com/bboard/q-and-a-fetch-msg.tcl?msg_id=001bSB ;

And here's a video on youtube of another test with a 9mm pistol (it did as much penetration as a sling projectile).     http://www.youtube.com/watch?v=NVQPBmhpI-Y ;   .

Ill be posting a pic and/or video of other tests, hopefully soon.

The typical 9mm pistol achieves a velocity of more than 1000 feet per second.    The kinetic energy difference between such a projectile and any sling projectile is considerable.
The reason that the bullet may only achieve limited penetration in a substance like concrete is due to the destruction of the bullet.    All of the energy is not expended in penetration.

In flesh, it's not unusual at all for FMJ (full metal jacket) 9mm rounds to completely penetrate the body.

A sling projectile 4-6 ounces in weight, going 150-250 mph. Compared to a very very lite bullet from a 9mm going faster. Even though a sling bullet is going slower, its still going to be heavy and have as much penetration since its heavy. The 9mm has a lite bullet, so that means in order to have as much penetration as a sling, it has to be going fast, since it is a lite bullet. I hope I explained this clearly. (And i hoped i spelled lite correctly.)

That is not correct, doubled velocity quadruples the energy while double weight only doubles the energy.

That may be true, but still, 4-6 ounces of lead approaching 250 mph seems like it would beat a little bullet thats prolly 1/5 of an ounce.

Oh, approaching 250 mp/h, u said 150-250 so let's take the middle. 200 mp/h, that is 320 km/h.
If you manage it, film it, post it and then I will shut up and get serious with my practice because I must be doing something fundamentally wrong in that case.

No no thats the total length of my short sling, from end to end. In fact its 7 1/2 ft not 7. And my long sling is 13 feet from end to end.

Oh so only 6 1/2 feet to the pouch on the long one..
Only over head with that one I am guessing.
But still let's se a video of the speed reached with that baby.
