lets wait and see how Power Draw turns out on the PTS,
for all we know we may see recoil added later,

A curious situation indeed. According to BattleTech lore all of the auto cannons are burst fire weapons, and their power and a corresponding recoil determine the effective ranges of their bursts...

The modern 155mm, 45kg projo with a Charge 2 moves about 450m/s and is capable of hitting within 1m of a target out to 2500m.

Well, that's modern cannon at 2,5 km (that is 3,6 degrees elevation direct fire, almost point blank) and 80 years old naval cannon at 30 km comparison. Not that we are comparing sniper rifle to the musket, but a sniper rifle to the long bow. Not fair.

As for the heat... Again it revolves around no-recoil system that generates heat. Plus really the BT universe unobtanium and unbelievelium used for guns and armor should have heat capacity lower than few J per kg per degree or else no chances for that low Mech heat capacity. Real cannon with that heat capacity would've melted after a few shots. Well. This is part of BT lore is really bad written.

Got an uncle who works at Raytheon (is in fact the CEO of the Raytheon Korea) who was telling me about these. theyre cool as hell

i think Future weapons did a Segment on that, its awesome but also scary as hell,

The M109 is Vietnam era though

Although not the tube or FCS, but the tube itself isn't inherently more accurate being a longer caliber, just much better range.

Well its the whole it can be programmed mid flight after being fired and has a HUGE area of mobility as well as accuracy

The really important part about it is the ability to completely negate what's known as Splash Shadow by having the round come down at a much, much steeper angle.

the other thing that was neat as hell that they were working on (that was declassified and was on the history channel) was the anti artillery ballistic systems and the radar systems they had to develop to do that.

Literally, hitting a much larger, explosive, bullet with another, smaller, radar guided bullet in such a fashion that it either destroys it or changes the trajectory in such a way that it no longer is dangerous to those in the target zone

----we need that for the damn long tom in this game lol

Well, the Army has been using AN/TPQ series Firefinder Radars since before Vietnam and they've gotten hellaciously accurate at figuring out the POO and POI and what type of projectile it is.

I just think its pretty amazing that the radar can be so accurate that tey can tell the type of projectile and whose it is etc lol

It's crazy high tech stuff. It's what I do now since I've reclassed to 13R, got to say that it's some impressive schit that I had no clue about.

Maybe in 3062 the unit "meters" is simply another than in 2016

500 m in the 3rd millennium equals to 5000 m in the 2016? Who knows

Half of the barrels on the WWII fields predated WWI and quite a few of the naval cannons predated XX century. Anyway, to make a barrel longer (reasonably) you need a higher pressure in the chamber, so either it is a better alloy (also in terms of microstructure) or thicker walls (higher mass inherently).
And higher range indicates higher initial projectile speed which actually makes shots more accurate by itself. The circle of probable deviation will shrink noticeably, but installing a better FCS shrink it much more impressively.
