A 1979 report, titled “Shooting effects of automatic weapons” lays out the statistical methodology that was used to test weapons during the Soviet era. There also is a huge resource of firing tables from 1977, that compare accuracy of various infantry weapons. Both experienced and average soldiers were tested with various weapons, from various stances, including firing from moving vehicles, at night, at even returning fire against muzzle flashes at night. From those tests, a measure of average shots to hit or destroy a target was measured against a variety of targets, including helicopters, cars, and enemy personnel.From one hundred to four hundred meters, the AKM loses a good 60 percent of it's energy .
The Soviets also measured these figures for burst fire against the ak74. Here the softer recoiling characteristics of the AK-74 start to shine. Firing from a supported prone position, a single three shot burst from an AK-74 is all that is needed to hit a running target out to five hundred meters. With the AKM, this can only be done out to three hundred meters. In a bounding overwatch situation, firing short bursts after a quick halt with the average soldier, the AK-74 required two bursts or six rounds to hit a standing target at one hundred meters, and five bursts or fifteen rounds to hit that same target at two hundred meters. With the AKM, eleven rounds are required at one hundred meters, and thirty-three are required at two hundred meters. The difference is dramatic, with almost double the rounds required with the AKM when bursting.
So It isn't really false bro , it's true to a good extent .
Also , Perhaps one of the most interesting tests is the longer bursts. Soldiers were instructed to shoot at a squad target using long bursts from one hundred to three hundred meters out. The number of shots required to neutralize 50 percent and 80 percent of the squad was recorded, against standing targets, and head and chest targets. From the prone supported position, the best soldiers needed twenty-two shots in long bursts to neutralize half a squad, and fifty-two shots to neutralize 80 percent of the squad with the AKM at three hundred meters. The average soldiers needed fifty-one and 119 shots to accomplish the same tasks. With the AK-74, the numbers for the best soldiers dropped to seventeen and thirty-nine, and to thirty-eight and eighty-eight for the average soldier, a marked improvement in full auto control and accuracy.
The accuracy could have improved in AK203 . But the current generation of AKs in IA service aren't known to be very accurate
