Supporters jcheeseright Posted August 29, 2013 Supporters Share Posted August 29, 2013 indeed, the whole 'you don't even need to hit a man with .50cal to kill him' is bullshit... 20mm maybe, 30mm almost certainly but 12.7mm no. Link to comment Share on other sites More sharing options...
Supporters Airsoft-Ed Posted August 29, 2013 Supporters Share Posted August 29, 2013 30mm is just totally over kill lol. The A10 Warthog doesn't need missiles, or rockets, or bombs. Link to comment Share on other sites More sharing options...

When the rounds are the size of a milk bottle you can't carry that much ammo... Link to comment Share on other sites More sharing options...

Supporters Ian_Gere Posted August 29, 2013 Supporters Share Posted August 29, 2013 The Navy used to call it "wind of ball" when cannon shot killed people without touching them. I dunno what size or weight a projectile needs to be, but you'd have to imagine that it can be caused at relatively low muzzle velocities, compared to modern firearms.

Supporters Lozart Posted August 30, 2013 Supporters Share Posted August 30, 2013 Or fire for that long, as the recoil can stall the plane Yeah.....that's not actually true. The worst the recoil can do in terms of flight speed is slow it down a couple of knots. The "stalling the plane" thing came from the problem with the amount of gun exhaust getting into the intakes of the engine. As gun exhaust is oxygen free it would cause a flame out in the engines, a problem that has since been fixed with a change to said engines in the form of a self sustaining combustion chamber. The gun is also mounted off centre to counteract the effect of the gun firing at the 9 o'clock position that would have otherwise yawed the aircraft. The casings for the 30mm rounds carried for the GAU8 are also made of aluminium alloy to save weight which of course gives an increase in the amount you can carry. It is also linkless for the same reason. The one piece of specialised field equipment the aircraft must have to operate though is the machine that loads the ammo.

Good question. There is a target practice round which may well be what you have a casing for as they are made down to a budget to keep costs down. All the "proper" stuff is Aluminium cased.
