But it's still limited in application then there was the issue of a shell that small being useful, air burst test where not superb and penetration of armor was pretty much identical to the 40. Geez I forgot what gun we are talking about,( XM8?) or that goofy one with the integrated 6(or so) shot grenade launcher.(xm29) if it's the later then as a standard issue rifle its a bit too much of jack of all trades master of none. not to mention a bit on the heavy side.
Talking about the grenade itself. I still think it would be a useful armament to have, even if you are right and it becomes a niche grenade. If for nothing more then the smaller calibre would allow a larger amount of grenades then current undercarriage systems. The fact you can just fire it towards the enemy without worrying about ballistic fire path all that much is still a nice feature.
Now if metal storm designed a weapon system around it....
O, okay gotcha. T'would be better than then 40mm as you wouldn't have to "lob" the shell, as a stand alone replacement(ie just a stand alone launcher) for the 40 I would like it. Just more accurate shells lighter weight and such. But as far as integration into a rifle(like the xm29 I would hate the weight and negligible performance. IDK what I would think of an underslung launcher though. 25 mm just seems too small.
I think video games have done a terrible job of explaining precisely why the grenade launcher exists. The reason is simple enough - the grenade is the most brutally effective close combat implement ever invented by mankind. They are small enough that one can carry many of them into battle, yet they have a startingly large radius in which they will render something dead or at least injured and unhappy. They are useful on the offense (either for supression or simply removing entrenched opposition without having to stick your head around a corner to shoot) or on the defense (not as good as a claymore but they can stop a rush, especailly en masse.). Unfortunately, even a well trained and skilled soldier is going to struggle to sling one more than 35 or 40 yards. Artillery in all it's forms is exceptionaly good at delivering steel on target and thanks to it's long proud history of causing death and serious injury it is still considered the king of the battlefield. Unfortunately, thanks to the limitations of the inherent design, these weapons have a miniumum range. Simply put, even a small (say 60 or 80mm) morter cannot fire on a target closer than a few hundred yards.
For ages, this problem existed - too close for the big guns but too far for grenades. So, at some point, an enterprising group of engineers set out to solve the problem of bridging this relatively explosives free gap. Early attempts resulted in the rifle grenade. While functional, the unit was cumbersome and difficult to use. For one, the average rifle was not designed for such a use, and secondly, unless one wanted to have a terrible day they needed to replace their ammunition with blanks in order to utalize a rifle grenade (there's a damn good chance trying to fire a rifle grenade with a live round will cause the grenade to detonate on the weapon). The first truly successful attempt was found in the form of the venerable M79 - which first saw service in vietnam. Like any weapon, it was not without it's flaws. In this case, while the weapon served admirably in the role of "deliver explosives to people you couldn't previously" and there were a wide variety of speciality rounds (buckshot, flare and the like) at the end of the day your grenider had only his grenade launcher and a handgun to his name. At long last, we arrived at the M203 (and the 30mm russian equivalent), which finally seems to have solved the problem. While it is a bit more difficult to reload, the simple fact that one's sidearm has been upgraded from "handgun" to "rifle" means the soldier has tremendous utility on the battlefield and can, at any given moment, act as rifleman or grenadier.
Of course, there have been attempts to improve the permormance. Higher muzzle velocity and better rifling can result in an easier shot, but in doing so one loses out on a great deal of other utility (for example, one cannot launch flares effectively out of a weapon with a muzzle velocity in the thousands of FPS - the flare would end up too high to be useful for illumination). Just as important, the indirect nature of the weapon is as much a boon as a curse - afterall, one can often lob the round over an intervening obstacle - something you can't do with a higher velocity round.
Reducing the round's size for any reason is an exercise in futility - at the end of the day you still rely on weight in explosive to do the job. At 40mm HEDP you have a lethal radius of but 3 meters (down from 5 for the M67 grenade). A 25mm round, even well designed will at best have a lethal radius of a meter or so - quite a step back. Weight of the weapon becomes important as well. At just over 8 lbs loaded, the M-16 is considered "light" compared to weapons of it's era yet even this weapon can rapidly become a burden. Once a weapon exceeds around 10lbs, your average person's accuracy will suffer in most common scenarios (shooting while standing, shooting while kneeling, shooting while prone without support). Once a weapon becmoes heavy enough, fatigue alone will introduce problems to the shooting equation.
Of course, all of these problems may be overcome with clever engineering at some point. The real trouble lies in the simple fact that, even as lethality increase, personal armor becomes more prevelant (and protective). Offensive technology has long outpaced defensive tech, but when you start looking at taking something very small and light (say a grenade fragment) and try and kill someone, even small amounts of protection start to make a huge difference. The flack jacket for example is nothing more than many layers of heavy ballistic nylon and will stop neither bullet nor a knife. Yet, it does an admirable job of slowing or stopping grenade fragments enough that they do not produce life threatnening injuries to the torso. Now, major nations equip their combat forces with legitimate body armor. In the case of the US military, the vest itself provides protection from common handgun rounds and the addition of the SAPI (small arms protective inserts) plates mean it does a fair job of stopping rifle rounds as well. With all components in place (neck/goin/throat protector, shoulder protector) a soldier becomes fantastically well protected against fragments to the vitals.
Of course, this is not always a boon - soldiers survive horrific injuries that previously would have left them dead on the battlefield thanks to the armor, but it often comes at the price of one or more limbs.
