The five-round application had no real time limit
per se. As to being able to perform said under battle conditions, the Boers were doing this to the British Army in 1900-1902; and hence the British developed the same requirement for themselves (and subsequently adopted by other Armies) until about 25 years ago.

Well funnily enough, the Chinese PAP sniper team recently came first in the international police and military sniper competition using a 5.8mm new sniper rifle.
The new Type95G uses the old standard machine gun cartridge for a boost in effective range and stopping power.
There is even a 5.8mm GPMG as part of the Type 95 family, so I don't think there is as much of an issue with the 5.8mm in terms of range as the NATO 5.56.
It is important to bear in mind that the Infantry Companies, Platoons, and Sections/Squads of most (practically all) Armies are trained and organized to fight on foot for the last 200-300 metres of an attack, usually (but not always) after having dismounted from an armoured vehicle (which itself may have been engaging the enemy from a couple kilometres away) just before hand, and to fight at close range, assaulting trenches, bunkers, rooms, etc., often with bursts of full automatic fire - and with the weapon under full control; something that cannot be done with rifles firing full-powered rounds. The weapons carried are designed and issued accordingly.
In
theory, the Infantry's armoured vehicles would take care of enemy troops and crew-served weapons at longer ranges. In
practice, the Infantry's armoured vehicles (IFVs, APC's, LAV's, etc.) could find themselves having to fight the enemy's tanks and other armoured vehicles, and not be available to provide long-range support fires to their own Infantry. By contrast, until a generation or two ago, Infantry was expected to march on foot into battle, and when conditions presented themselves, might start firing at targets out to about 600 metres (especially if they were on the defensive). A bit of an oversimplification of the tactical history of modern infantry, but it'll do for here and now.
Punching paper out to 1000m is common with smaller cartridges; many target shooters prefer the 6mm PPC and other similar rounds, and even 5.56mm is now used in F-Class competitions. The advantage of using such lower-powered rounds in shooting competition (which, incidentally, is a factor that can't be quantified on a ballistics table) is
low recoil - on 6mm/.243 calibre weapons and smaller, there is almost no recoil worthy of the name, and hence very little disruption of aim at the point of firing and during the follow-through, relative to more powerful calibres. Smaller calibre rifles, under the right conditions, are more accurate than larger calibre rifles precisely because of their relative lack of recoil (though they are of course much more vulnerable to wind drift, etc.) But they have to sacrifice hitting power to do so. It would be highly inadvisable to attempt to shoot anything larger than a coyote with such a calibre weapon over about 500m. In many jurisdictions it is illegal to use a calibre smaller than 6mm or .243" to hunt deer with, and deer are much the same mass as humans, only tougher.
The perceived advantages (simplified logistics, more ammo available) of having only one major small-arms calibre in the Infantry Platoon or Section/Squad are sometimes outweighed by the disadvantage of not being able to reliably kill what you hit at ranges much beyond 200-300 metres. Or penetrate obstacles at short range such thick foliage, concrete walls, or whatnot in order to kill or wound enemy hiding behind them.
As to whether there is a substantial difference between the 5.56mm and the 5.8 mm, any such difference itself is unlikely to be of much comparison to the difference between them on the one hand, and full-power rounds such as the 7.52x54R and 7.62mm NATO on the other. Those two calibres have decidely noticeable recoil, but will despatch two-legged targets at ranges of 800 or 900 metres, which 5.56 and 5.8 mm will not. The 7.62x54R and 7.62 NATO rounds were the typical GPMG and sniper rifle rounds for many decades even long after the introduction of the lower-powered assault rifle rounds, and for good reason - at the ranges they could be accurately used, they worked.
But now that kill shots over 1000m or behind armour, masonry, or other heavy/thick media are desired, the 7.62mm itself is being largely replaced in sniper rifles by much more powerful calibres, such as .300 Win. Mag and .338 Lapua Mag, and of course the .50 BMG, etc.
