You have to apply alot of suspension of disbelief to battletech/mechwarrior. I mean lets take a MG. Now we all know that even something like a .50 cal MG can effective engage targets out to 2000 meter in real life. However, it isn't able to penetrate alot of armor at 2000 meters. Therefore I always looked at it as less a factor of not being able to reach the target at 2000 meters and more of it just can't hurt Mech armor at those ranges. Instead it had to be at less than 150m to actually effectively damage the armor.
Of course then the introduced Light and Heavy MGs which blow that idea out of the water. I mean the heavier the MG, the more range it should have and the more it should effect armor. Instead the ranges get shorter for some reason so poof there goes my ability to suspend my disbelief. <sigh>.
Oh, the explanation for that is easy: shot spread.
A GAU-8 has an effective range of 1200 meters, but at that range, 80% of the bullets fired will hit somewhere in a circle 12 meters wide. You average mech is around 10 meters tall and is often thinner than it is tall. A weapon performance like that will have bullets hitting the mech all over the place.
By contrast, a burst from a Battletech (not so much MWO) AC will have an entire burst hit only one location on a mech, which is MUCH smaller than 12 meters. Ergo, AC's need to land very tight shot groups of bullets in order to do the damage they do, and if the bullets spread out to much, the damage to armor from bullet hits becomes negligible and is counted as a "miss" under the TT rule system.
Yes, a 50 cal can engage targets at 2000 meters. But for most targets, it only needs one bullet to hit in order to inflict major damage or injury. But for an ARMORED target? The bullet would just bounce off, maybe chip off a small piece at best when doing so (which is what seems to happen in BT).
In short, BT ACs need to land very tight shot groups in order to do damage, which drastically reduces their effective range. This also explains why effective range shortens the heavier the AC gets. If you actually look at the stats, the weight of ammo goes being thrown downrange goes up linearly as AC rating goes up, but AC weight does not. There's relatively less mass per weight of shot in the heavier ACs than the lighter ACs, which means the heavier ACs have less mass to absorb recoil when shooting, which in turn means they're more prone to having their barrels dragged off target when firing a burst, which in turn shortens their effective range. Outside their effective range, an AC will hit with the first bullet in a burst, but the rest of the burst will go anywhere and everywhere EXCEPT the target due to recoil.
