I shouldn´t post with sleep deprivation.
Anyway, yes the mech was oversinked.
Now to optimise it I would put the ammo in the arms with CASE II installed, so as to protect the pilot from taking damage from ammo explosions. Splitting the ammo to both arms means I still retain fighting capability with less ammo if an arm gets blown off. One ML is installed in the head.
If you think the amount of ammo is too much you can always choose TC SRM ammo for double the firepower for half the amount of reloads the mech can hold.
