Sniper rifles are very well manufactured, well maintained, they usually use special ammunition which is fit for sniping with the specific gun for the best accuracy, they shoot on semifire at a relatively stable targets, they have good scopes to aim with and most of all the operators are usually highly trained and talented experts.
WWII .50 caliber machinegun is about nothing of these..
Manufacturing quality was probably at an average level compared to nowdays production... including also manufacturing of the ammunition, which were in varying types.
In WWII they didn't make a big issue out of metal wear!
The spare parts for planes alone must been enough to give a life long nightmares for FAA inspectors.
Where a sniper can hit man sized target from over 1.5km, I'd give quite smallish chances for a person with 100 rounds and a .50 cal machinegun to hit a fighter with any chance for some kind of actual damage.
Hitting alone is so-so and thats required to make damage... then theres only very small areas on planes where the hit will do damage.
Once again, to qualify with the M2 .50 cal you have to hit a BMP
(frontal) sized target at 1,000 yards using less than 14 rounds. Open sights, flex. mounted. It can do this without much trouble by walking one or two bursts into the target. I have no doubt that if you present the aircraft equivalent of a stationary plywood target at 1,000 meters, then it wouldn't be too hard to "walk the rounds in" in that environment as well.
And if you ever saw an M2, or had even the slightest amount of RL experience with the weapon and its capabilities, you might know better instead of spouting off ill informed opinions. The M2 is not a stamped, cheap modern weapon. It is highly machined and hard to replace even today. The only real wear component is the barrel, wich is easy to replace and which were replaced regulary in USAAF units because of the abundance of spares and materials our airforce enjoyed.
As far as sniping capabilities, M2s were used in single shot mode as sniper rifles in VietNam.
Marine Corps sniper Carlos Hathcock recorded a 2,500 yard kill against the Viet Cong using a sandbagged AN/M2HB and 8 power Unertl telescopic sight.
I think that if you locked convergence at 400 yards max much of the whining would die down.
