"effective range"
This can defined several ways. The US Army says it is the distance that a typically trained soldier using issue rifle and standard ammunition has a 50% hit probability on a man torso target.
The US Marines say anything within sight distance of a Marine with a rifle is in “"effective range”.
I gotta give it to the DevilDogs- The Marine definition is a little overdone but not much- they practice, all ranks and all jobs- drivers and clerks, helicopter mechanics and pilots, IT specialists and signalmen and cooks- every Marine is a rifleman FIRST.
As an Army Infantry officer I envied their general proficiency at the unit level. I had many soldiers who could shoot extremely well, but the Army follows slightly different training doctrine and our training was generally not as extensive or performance demanding as Marine rifle training.
It should be apparent that "effective range" is highly dependent on the shooter and is also closely tied to the appropriate choice of ammunition for your weapon. An AR-15 with a 20" 1:12" barrel may have an effective point-target range of 800 yards when firing 55gr ammunition, but then upgrading to 69gr or 77gr ammunition would see the effective range drop dramatically due to the inadequate twist rate for the higher loads.
Sniper rifle effective range: Sniper rifles are judged by entirely different criteria. A sniper rifle's effective range is judged based upon the range at which one shot, carefully fired by an expert marksman, is guaranteed to strike the target. Sniper weapons tend not to list point or area effective ranges, as sniper rifle effectiveness is not calculated with 50/50 hit ratios.
Cartridge Maximum effective range
7.62×39mm 600 m
5.56×45mm 800 m
7.62×51mm (.308 Winchester) 800 m
7.62×54mm R 800 m
.30-06 Springfield 800 m
7 mm Remington Magnum 900–1,100 m
.300 Winchester Magnum 900–1,200 m
.338 Lapua Magnum 1,200-1,500 m
.50 BMG (12.7×99mm NATO)
12.7×108mm (Russian) 1,500–2,000 m
14.5×114mm 1,800–2,300 m
So what is the range of a 50 cal cartridge? Distance and still have stopping power. Do snipers use this cartridge? If so out to what range?
The 50 cal Barret, commonly in jar head lingo as the SASR, was pushed in by the Navy and the USMC doesn't fancy it, altho we use it. It can engage targets to 2,000 meters. It weighs 28.5 pounds. Not much of a battle rifle, I fancy the SMAW rocket myself. (The SMAW is an 83mm man-portable weapon system)
It's easy to forget, all some of us do is shoot, patrol, hump, swim and shoot more. The Combat Arms side of the military is highly trained and prepared.
It's common to hear of 1000-1100 meter confirmed kills, with the M40 rifle. There was an article before I left were a Reservist Sgt got a confirmed kill on the second shot, if I remember right the distance was slightly over 1260 yards
