>>511336303If you're laying ambushes based on static positions, with intermediate cartridges like 5.56 your effective range is much lower than your visibility on target is likely to be. If you have terrain that prevents anyone from seeing or shooting past 600m it's fine, but if you are in the open, you basically don't have the range or effect on target for the principle of line fire or overlapping fields of fire, or weight of fire to live up to what intermediate cartridges are meant for, and you'll be outgunned by anything with a full sized rifle cartridge in accuracy and effect on target, even if you put out 20 rounds of 5.56 for every single 7.62 coming your way, you're missing by feet and he's missing by inches at the distances supported by modern optics. a bunch of rounds missing by feet is a different kind of suppression to one round missing by an inch. I've been shot at a couple yards out before, it's not paralyzing, but a shot landing a few inches away fucking does spook you. .22 calibre rounds just don't carry the energy for 6-800m sengagements, sure you want weight of fire, but that's secondary to accurate fire.
To ambush them, you'd need to basically have them walk through what should be visibility into a target area, or enter an area where they lack visibility until they're in the killbox, and since your effective range really falters past 500m, you're ambushing people at distances shorter than that, within a couple hundred meters, where you no longer get to use distance for concealment and surprise. Your killbox only springs when you're all in cqb, your no longer have the advantage of a prepared position when you're in cqb gunfight approached by a general angle, you no longer have distance or concealment to support ambushes because you're all spamming fireballs in cqb.
Your gun needs to shoot accurately as far as you can see.
