@ 2.5 miles
Depends on which machinegun. The M60 has an effective range of 1,100 meters. The M2 .50 Browning is 2,000 yards.
The only way to know is to shoot both.
some shoot far and some dont so they all dont shoot the same length
Very far
Distance depends completely on the caliber and the amunition such as bullet and weight. Recommend you check a rifle ballistics chart which can easily be found doing a google search.
how far does a 50 caliber sniper rifle shoot accuratly
Type of action has nothing to do with how far a weapon will shoot. Caliber and load is what matters.
As far as I know browning did not have any firearms made for them in australia.
yes
ALOT!
How far will it shoot and hit something??? i wouldn't put it past 300 - 400 yards comfortably
They can shoot as far away as they want. There have been successful shots at well over a mile.
