A bit pedantic, but worth clarifying - p 104 of Total Warfare states "Any hit against the dumping unit on any rear location during the Weapon Attack or Physical Attack phases inflicts normal damage, but it also causes all dumping ammunition that can explode to do so. (Rear locations include the rear torso on ’Mechs, but not the turret on a vehicle that mounts one.)"
Based on the wording, it's safe to assume that arm hits do not cause ammunition explosions. However, is the part in parentheses a comprehensive list of "rear" locations for this context (meaning an ammo explosion on a dumping 'Mech ONLY occurs upon an LTR/CTR/RTR hit), or is it in addition to any possible other "rear locations" that may be present, such as the left/right rear legs on a quad 'Mech?
