Aren't LRMs treated in groups of 5? So theoretically, one LRM20 launcher might fire 20 missiles, and another 5, and another 10. That would probably clash with TT AMS mechanics, however.
Though, the claim that ACs fire different projectile sizes and have different rates of fire despite the same classification also doesn't seem to be represented well in the rules, either. If an AC/20 really fires sometimes 1 big bullet and sometimes 20, why do they all land at the same hit location?
Well - of course you can use that approach - same for ACs
To admit - it is the most common - in newer novels.
But the good old Gray Death Legion - used other design idioms.
The AC 5 Whirlwind of the MAD - 3D was a 120mm caliber gun firing 5 shells per shot. With a ammunition storrage of 20 clips.
The AC 5 of the Rifleman were 60? or 80mm firign 10 shells.
The AC 10 of the Centurion was 80mm too.
The Pontiac 100 AC 20 was listed as 60mm gun firign 100 shells in 6 seconds. (thats 1000 rpm)
- what about the missiles - In
Tactics of Duty the Doombud LRM 20 of Alexander Carlyle fired a dozen missiles. (I read all the novels in German - so i don't know if there are translation mistakes)
A dozen is interesting (the Archer has 12 shots per launcher) - because it is a known mistake for some players that are new to BT - to place 3tons of LRM ammunition to the LRM 20 - because 3tons = 18shots,
So what if you look behind the figures - try to imagin how a weapon could work - when you only have the artwork:
here are some examples:
Condor II -> Valiant Arlabest LRM 15 -
You see 16 large war heads - and I don't think that it is possible to reload them through the launcher - so the Condor II can only fire 1 missile per tube. That means its 16 shots (2ton of ammunition = 16 missiles) that means each missile deal a total of 15 damage.
That damage in 5 brackets could happen: proximity fuse - and the blast damage the Mech. Sub Munition - AMS or other Hard Kill system - can shot down the missile - before it arrives - reduced damage through blast - or it shots down some of the sub munition.
Or look at that Atlas:

You have something that looks like a bit bore recoilless rifle
a launcher with 6 tubes at the chest and 5 tubes at the hip next to the recoilless rifle.
Next you have a tiny long barrel cannon at the other hip - and something black - were i don't have any idea what it could be:
So this Atlas may have a reloading system (revolver) at the chest - launching 6 missiles (LRM) - and a OS LRM launcher at the hip - while the SRM is the big bore recoilless rifle.
However - at the TRO 3025 revised cover

The Atlas is - "fixed"
The SRM 6 at the hip has 6 starters (with 1 - moved back)
The LRM has 4x5 starters - but in the lore are named only 5 tubes
Quote
the designers decided to install five tubes with a feed system that can shoot four salvos within 10 seconds
I don't like this explanation - its to "boring" like in the novels were the writer just wrote down how the weapons hit - not because it is interesting but because he has to fill pages (Prince of Havoc is the best example - for this skill - I know the reason however)
OK - most Mechs have the correct number of tubes: only vehicles are curious:

The tripple barrel Chin mount is a AC 2 - and the launchers (2 at each side) is a SRM 4
Striker:
The Big tubes - are LRM 10s and the small tubes are SRM - doesn't look like a good ratio
BUT that is not only part of the missiles:
here the favorite example of artworks gone ill:
THE BIG bore is a LBX 20 - with ammunition in the rear legs...how could that work?
Never - you can not explain the LORE of cluster ammunition - because that Gustav class grenade has to be stored somewhere. So the best explanation - if you need one is - that this BIG Bore is a Metal Storm system - all small caliber shots are stored withing multiple barrels - (did you read John Ringo -
When the Devil Dances, 2002 - the 40mm system with 100 barrels or the 105mm with 12 barrels) - a cluster shot is one grenade of each barrel - a slug round is - all shots of a barrel.
Well you can explain it in that way - or you modify your barghest mini to be a 7 version with 4 laser and a MML
So I'm still not done:
Look at the two lasers of the Barghest - that are large lasers.
Well now take a look at the arms of that thing:

thats large lasers too:
or the "pistol"
Thats a large laser - too.
That is just a small trip into the madness of BattleTech.
Lets think about if all those guns with all there different manufactuers and behaviours.
I think it is more simpler - to say all Lasers, guns and missiles have the same performance - and leave the details to the players. (for example - like assault rifles - different calibers, weights and manufactuers - but in the end they are good at medium range - and can kill people)
In general you can say:
BT - weapons are to heavy
BT - ammuntion is to light
BT - armor is magic
