message: Hello,
I'd like to see added to this page the following links:
http://funditor.110mb.com/sling2.html as How To Make Your Own Sling
and
http://funditor.110mb.com/KeyChain_Sling.html as Keychain Sling, a How-to
Both of these sites provide further information on slings and have been embraced by many in the slinging community (As moderator on slinging.org, I know this well!). They will, in many cases, be celebrated by the Wikipedia reader who finds them. Therefore, I ask: Does anyone object to their inclusion in the external links section?

message: Re: "The reason why the almond shape was favoured is not clear: it is possible that there is some aerodynamic advantage, but it seems equally likely that there is some more prosaic reason such as the shape being easy to extract from a mould or that it will rest in a sling cradle with little danger of rolling out."
An ellipsoidal projectile will 'roll out' of the sling in much the same way an American football is thrown by a competent quarterback - the sling spins the bullet, enhancing range and accuracy.  As a side-benefit, the bullet would hit point-first, maximizing the force of the striking surface.

:The problem of rolling out refers to a bullet that is resting in a sling cradle. A cradle is typically diamond shaped and will wrap around a bullet such that a long elipsoid is unlikely to come out but a sphere could roll out of one of the open ends.
:Just what happens when an ellipsoidal projectile is thrown has been much discussed on the slinging.org forum. Some experimenters certainly reported spinning, but could not confirm that it spins in the way you suggest -- ie point first. Personally, I find it hard to see how that would happen. Gaius Cornelius 13:15, 19 October 2006 (UTC)
replies: text: From personal experience, the spin imparted to a projectile is determined by the orientation of the sling, which in turn is (mostly) controlled by the slinger.  Proper technique allows one to impart a football spin to a projectile with good repeatability; improper technique allows the sling to twist and the projectile may spin any which way. --Swwright 20:33, 23 January 2007 (UTC)

message: RE: "Ancient authors seemed to believe, incorrectly, that sling-bullets could penetrate armour... ... it seems likely that the authors were indicating that slings could cause injury through armour by a percussive effect rather than by penetration."
Citation needed, indeed.  
A lead projectile, shaped like an American football (spinning - using the same physics), hurled with great force (multiplied by the action of the sling), hitting a bronze helmet or breastplate, *would* penetrate said armor, and easily.  I believe that there was confirmation of this on a cable television program (on either the Military Channel or History Channel).  Early firearms, using round shot with only slightly-higher flight speeds, could penetrate iron and steel aromor.
Discussion?  Confirmation?  Mythbusting?

:The ancients certainly did belive those things about lead sling-bullets although I don't have a citation to hand. I don't know of any ancient evidence that sling bullets actually did go through armour. Sling wounds are rarely mentioned, Julius Ceasar tells of a badly wounded centurion hit in the face although that was not through armour. I have seen lead sling-bullets failing to make much impact on reproduction shields, although I appreciate that that is a bit different to armour. If there has been some experimental archeology, then I would be very interested to hear about it although that is unlikely to settle the issue - compare with the argument that rage over the longbow! There are some figures for velocities of comparable weapons in "The Balistics of the Sling", I don't have my copy to hand, but from what I can recall even the earliest firearms achived much higher velocities than the sling. Gaius Cornelius 13:15, 19 October 2006 (UTC)
replies: text: Found the reference I had in mind: Thom Richardson, Ballistic Testing of Historical Weapons Royal Armouries Yearbook, Volume 3 1998, p50-52. Various sling and bullet combinations achieved about 30 m/s and were completely resisted by a 2mm plate. A medieval handgun with a 50gr charge which produced a velocity of 180 m/s and was the least effective of all the guns tried. An arquebus  with a 50gr charge produced a velocity of 378 m/s and easily penetrated two 2mm plates clamped together, the same weapon with a 90gr charge achieved 520 m/s and just failed to penetrate a 6mm steel plate. Gaius Cornelius 20:25, 23 October 2006 (UTC)
replies: text: I have re-inserted the "citation needed" on it being incorrect that a sling could penetrate armour as no citation is present (despite this discussion) and the examples given are insufficient to support a claim that slings can't penetrate armour. "Armour" is a vague term and could mean anything from hardened leathers or thin hammered bronze to the more modern armours of the time of the authors (like the roman lorica); variation in quality of metals might well allow some armours to be penetrated.  Looking at bronze armour, the plates in achaean armour (http://en.wikipedia.org/wiki/Dendra_panoply) were ~1mm thick, which is bronze and half the thickness of the plates tested in the above mentioned study.  Virgil's writing (quoted in that section) is recounting a much earlier tale, and it's entirely possible that slings at that time could penetrate the available armours.  I haven't seen testing, but 30 m/s is quite slow for a sling; I believe you can hit twice that speed (4 times the energy); indeed, the world record distance would require a launch velocity of nearly 70 m/s ignoring the effects of air resistance, so the initial velocity was likely well over 70 m/s. --Synaptophysin (talk) 14:47, 25 July 2013 (UTC)

thread_title: Maybe we should move "Kestros" info to its own page

message: A citation has been called for, concerning this sentence: "In the latter case we may imagine that they were impressed by the degree of deformation suffered by lead sling-bullet after hitting a hard target."  I have found several sources of information concerning this, two of antiquity and one modern.  I will give the citations and then ask how best to add them, because I am rather new here...
Lucretius, in his "On the Nature of Things", says (in William Ellery Leonard's translation): "A leaden ball, hurtling through length of space, / Even melts."
Virgil also says something about this in the Aeneid (John Dryden's translation): "Him when he spied from far, the Tuscan king / Laid by the lance, and took him to the sling, / Thrice whirl'd the thong around his head, and threw: / The heated lead half melted as it flew; / It pierc'd his hollow temples and his brain; / The youth came tumbling down, and spurn'd the plain."
These two translations are available at The Internet Classics Archive (http://classics.mit.edu/index.html).
The modern source is a member of an internet forum devoted to slinging.  I know him only as "AjlouniBoy" which is his username at Slinging.org.  He has himself slung an lead fishing weight against a concrete block; the impact seriously deformed the projectile and generated enough heat to be noticeable.  His message on this subject is at http://slinging.org/forum/YaBB.pl?num=1130967387.
So, how do I get this information into the article?  Just start writing?  Add footnotes?  Thanks in advance for your advice and assistance!  --Swwright 01:31, 24 January 2007 (UTC)
replies: text: Thanks for your encouragement, Gaius Cornelius.  Bold it is, then!  I added three footnotes about lead glandes melting in flight, citing Lucretius and Virgil and a modern slinger of my acquaintance, and a new "Footnotes" section. I also removed the  tag. --Swwright 23:21, 26 January 2007 (UTC)
thread_title:  Melting projectiles 

message: In the section on construction, the text says that braided cords improve the design of a sling because they resist twisting, while later in that section, it mentions that braided cords improve the design by not stretching.
Theoretically, a braided cord would be more likely to stretch than a twisted cord simply by the nature of how a braid is made.
Can anybody take a look over that (the entire section could use a good reworking, really, as it seems very informal and conversational)? ~ Caejis (talk) 04:04, 18 April 2008 (UTC)
thread_title:  Conflicting Information 

message: This passage sounds like a dialogue and needs a knowledgeable re-write: An archer can easily shoot from behind protection or fortification — including downwards from the top of a wall — whereas a slinger must expose his person to the missiles of the enemy - not true, an experienced slinger could easily arc his stone over any intervening object. An arrow is more likely to penetrate armours or shields due to its sharp point, but a sling could do damage to relatively soft armor (such as quilted cloth) by percussive force without the need to break the surface of the armor itself. It has been said that to achieve range and accuracy with a sling required a long period of training. However, this is probably no more the case than for the bow, and when the target was a mass formation great accuracy was probably not so essential. This is incorrect - accuracy with a sling is usually only acquired after several years of use - accuracy with a bow can be achieved in a matter of days. — Robert Greer 
:I certainly agree that some expert input, not to mention some cited sources would be very welcome here. I guess that the point about fortification is that a slinger needs to move his entire body to sling - at least this is true if the sling is to be used to maximum effect. As a re-enactor, I have had a go at slinging; I am certainly no expert, but would think that it is difficult to sling out of a narrow window or between crenelations and very difficult to aim for a particular target under some circumstances. Also, while it is faily easy to imagine an archer to lean out to take a downward shot from a window or crenelation, it is difficult to imagine how a slinger would shoot effectively at such an angle. In any case, there are certainly plenty of ancient illustrations of archers shooting from fortifications, but I don't recall seeing any of slingers. Gaius Cornelius (talk) 17:14, 12 June 2008 (UTC)

message: How far can a slinged stone go? 
According the article "In general, a sling bullet lobbed in a high trajectory can achieve ranges approaching 600m". A recent experimental study in the Journal of Archaeological Science suggests skilled Quechua-speaking herders in Puno, Peru using adjacent cobbles could not do more than 130m. New experimental data on the distance of sling projectiles 
The statement in the article comes from a paper that is online The Sling in Medieval Europe 
Reports of estimated range of the sling varies in recent literature. This may stem from the inability of historians to find individuals who can properly demonstrate the sling. The bow, crossbow and firearm, if operated correctly, will produce the same effect the weapon had hundreds of years ago. However, the sling requires tremendous skill, and only people who have had extensive training can claim to match the ability of ancient slingers. Existing literature quotes ranges as little as 150m to as much as 500m (Demmin, 1964; Hogg, 1968; Korfmann, 1973; Wise, 1976; Connolly, 1981; Ferrill, 1985; Richardson, 1998b). Larry Bray set the Guinness World Record for a stone cast with a sling in 1981, achieving an impressive range of 437m (Norris, 1985). In retrospect, Mr. Bray believes he could have surpassed 600m mark with a better sling and lead projectiles (Bray, Personal Communication, March 21st, 2004). Presumably, professional slingers of antiquity who trained from childhood and relied on the weapon in battle could achieve even greater distances, perhaps approaching 700m.
I am confused since the sources conflict. The text needs to be changed but I am not sure how. --LittleHow (talk) 14:27, 11 August 2009 (UTC)

message: I haven't looked at this article in years.
In the intervening years the article has gone from giving roughly comparable weight
to the military stave-sling and the David-style sling, as described in the Bible, to
devoting almost all its text to the style of sling described in the Bible.
I strongly suspect that the military sling was of greater importance.  Geo Swan (talk) 15:30, 19 July 2011 (UTC)

What's clear is that this method was described in the fictional novel The Clan of the Cave Bear:
What's less clear is whether this method has ever been performed outside of fiction.  The folks on the slinging.org forum don't know of any real person who has been able to do it.
If this text is ever put back in the article, it needs a huge  tag on it, unless it has reliable sources.  --Hirsutism (talk) 21:19, 11 October 2011 (UTC)

message: I can't believe it is as simple as described in the article. 
"The sling essentially works as a extension of a human arm. By increasing the length, it allows stones to be thrown much farther and harder than they could be by hand."
I am hoping to pique the interest of someone with a physics/engineering background, in the hopes that a more accurate description of operation can be found.
For a start I believe the effective radius of the sling is decreased during the moments immediately before release, increasing projectile energy.
I would prefer to remain anonymous and simply seed a discussion as this is not really my area of expertise. I hope this isn't too much looked down upon 49.225.148.211 (talk) 23:12, 29 October 2021 (UTC)
