Most of the info you can get directly of the Armys web site. Lots of info on there
Effective range (military specifications)

Effective has to be related to the target surely. You can reliably hit figure 11 at 800 yards with 5.56 NATO Radway Green 62gr ammo but if that was effective then they wouldn’t have had an emergency procurement of 7.62 rifles in Afghanistan.
Seems a complex analysis to me

I think that’s only the accurate ones !
That was more to do with snipers not getting the time to build a shot.
Getting a cumbersome 338 into position is a different beast to getting into position with the 7.62 sharp shooter.
High mag scopes were utterly useless in a lot of cases , as was the 338 round

Effective Range is very very much open to discussion. As a deer stalker effective range is the range at which the shooter, rifle, cartridge, sighting and support system can reliably and humanely take a deer or similar sized game animal. We are concerned about putting a bullet through the vital organs so that the deer doesn’t go very far and dies with a few seconds.
This is a very very different requirement to taking a snap shot as you are running through the African bush after insurgents as the Rhodesian Troopies did with open sights and an SLRs or trying to put a bullet through a generator set that will knock out the power of an enemy command post.

To save everyone here's an answer. The answer is in a table contained within a tamm used by field commanders. Explains max effective ranges etc.
Effect is military terminology and not related what you think "effective" is.
Will also find that machine gunning hasnt changes since ww1 in concept and the ramge tables we have are exactly the same as draughted up then.
Gpmg employed in sf role is used out to 1800 in map predicted fire and the sight goes to 2500. Is it accurate- no. Is it effective - yes.
Your not using it for precision fire, its probably not going through body armour at that range. But what it does is pour 7.62 ammo into an area creating suppressive fire for a platoon attack on an objective or a block against the enemy force.
I dont care who you are - you are not walking through that unless your in armour that can take 7.62 - to get around that you just lay effects on top of eachother to really screw them up.
Obviously it breaks down for example if your using a weapon system against an enemy in armour, overhead cover, light cover etc.

If you want a quantitative report you should get a copy of Bryan Litz phone App "Applied Ballistics Quantum" which has a paid "Pro" level that can calculate a "Weapon Employment Zone" function. Inputs are such parameters as :
Rifle + Shooter precision (grouping)
Bullet wt, velocity, ballistic coefficient
Uncertainty in: wind estimation (really the main factor over 300m), range estimation (huge unless the user has a rangefinder), slope, barometric pressure, muzzle velocity etc
You specify the target size, it gives a graphic of 1000 simulated shots and hit percentage.
The remaining KE and velocity at target are also reported of course.
Here is the output for a 3006 165gr @2800 f/s shot from a backpack rest with good dialup scope (0.4 mRad dia 5 shot grouping) at a laser ranged 400m with realistic wind uncertainties (sd 2m/s full value) : 42% hit probability on a 20cm diameter circle. At target we have 1509 ft.lb KE, velocity is 2029 f/s (marginal for expansion of a hunting bullet on a deer)

CG 45 were accurate too 200m and sighted even for 300m, 9mm+p submachinegun ammo.
