Dropping the CASE gives 20 salvos by my math, and the LGR is unusual in that it really can use significantly more ammo than other weapons thanks to the extreme range. It is very common to come across machines like the Thunder Hawk or Pillager dug into good defensive terrain to make the enemy come to them, but if you have LGRs you can park outside their range and lay into them until they move. If they are smart, they will realize that they can generally weather 16 rounds of LGR fire and stay put until you run dry so you want significantly more ammo to let you wear them down and force them to move up to engage the rest of your forces which should be dug into good positions just outside their range. Thus many players like to carry 24 or even 32 rounds for their LGRs to allow them to inflict as much damage as possible before the enemy gets frustrated enough to engage. The Medium Lasers on the other hand are really not doing that much for you because this 'Mech does not want to be that close to the enemy if it (or more accurately, its allies) can avoid it, so trading them for extra ammo does not really cost you very much.
That said, I am happy with my own -2M variant which takes things a different direction by building off the -2A (modified to use an Endo-Steel chassis) so it uses a quartet of MPLs for short ranged firepower which gives it more accuracy which helps against the fast movers that will be trying to pick it off at the cost of a bit of raw damage. Seven tons of ammo give it 28 rounds of endurance on the guns and 18.5 tons of armor make bringing it down difficult.
