I've been waiting forever for an Assault-Jager and here it is. I know there's a couple other very similar builds to this but I feel this is the best min/max King Crab-000 if not in general. I feel anything lower than a STD325 is too slow and even more important than pulse lasers or AMS. Upgraded Chainsaw IM / Jager-DD for glorious dakka. It's great at PUG carrying as well. Goodbye MC.... Must master this beast.
I'd find the tonnage for at least another ton of ammo, out of leg and/or arm armor. For the comparison I also have 240 shots on my Jagermech, but that's only because the build is severely restricted by tonnage and crit space, sometimes it's short.
You can just drop one of the lasers but I've been running this as a 'PUG carrier' and it easily does over 800 damage with around 15-40 shots left most of the time. So I guess you could take more ammo if you plan on a longer game? 240 rounds is 1200 damage, so if you aim well and the lasers are adding 10 damage at closer ranges I really think it's enough.
