I've never had a problem with necroing thread that are like this one. If someone want to discuss this type of thing, this can just as easily be the clearinghouse of information.

I am not a bow expert, but it is not difficult, for me at least, to understand penetration as a mixture between projectile mass and velocity and strike area, which yields power delivered per unit area. If I understand basic bowcraft, you get more overall stopping power from a large (higher grain) arrow than a small arrow, but less accurracy. This means that loading the projectile with energy is a function of some kind, and not just a gross number as in you get such and such joules or watt/hours or whatever, per pull (also, the last inches of pull seem to load more, so longer arrows seem to have more power).

So, most bows of whatever type should have fine penetration.

There was not a great deal of variety in materials for bows in medieval times, and crossbows were generally not 5 feet wide, as a long bow might be tall. From what I have seen, long bows also flexed quite a bit more. This would generally seem to favor the long bow for loading capacity over the crossbow, even if it take more weight to pull back the string. Modern crossbows, though still often narrow, flex like crazy, to a point I've never seen anyone do with a bow. Compound bows still seem superior however. Though it's likely there is a comparative crossbow variety as well. Most compound bows are composite of some sort and so are crossbows, but compound bows seem to be more wood like, whereas crossbows seem to be more like metal springs. I haven't a clue which is necessarily more powerful, becaue the compound bow is generally much larger, and crossbow remains nocked. Thus, there is not much of a clue from user interface. My assumption is that at the high end of penetration in the modern world are sophisticated compound crossbows that are quite large and are pulled back with a mechanical device. This seems like the most reason and sane way a person could load a projectile with as much force as can be reasonably accomplished.

But what about slings? I looked around at sling information, and it seems that slings remained effective for a very long time. Even now they have their harrasment value with certain irregulars. They use a blunt object, so the object needs to be very heavy or very dense. Indeed, when there was metal armor, the slings used lead shot, which was quite deadly, on the Romans.

However, the ranks of slingers dwindled, and this is likely to be due to skill and culture limitations. I've never used a sling, but they aren't and obvious as a bow, and certainly no were near as obvious as a crossbow.

In ancient Israel, they have found a lot of sling stones, some quite large (fist size!). There is some evidence that the Ancient people of the region used slings to achieve great results (also explaining why other nations came up against them with calvalry and chariots). One -could- assume that sling use was a sort of national pass time in the region. This would explain the various size and sling projectiles as well, and the skill involved. Contemporary persons skilled with the sling are quite effective and accurate. I would concede that such a situation could easily be like that with English Longbowmen, only, it seems, on a grander scale, as all the peasantry use the sling. I can picture granny giving the little ones their first sling lesson, because the men are to busy seeing who can sling the 3 pound monster stone the farthest.
