I started from "kintaro2", 6xLRM5 and TAG. bUT None of my mechs is ammo-only. So I got back to mechlab, and present you the most FUN build I've found for Bushie P1: BSW-P1 "kiTARADO3" 6xLRM5 (4t) RAC2 (1.5t) ML XL280 Avoid using both the missiles (allways chainfire) and ML/RAC2. Can be used for short time. But usually I'm either shooting missiles far away OR I'm RAC'n and Lasering someone nearby. I'm often running out of LRM, then I rush forward until I'm out of RAC2s... still a ML to use! So I tried replacing the DHS for +1 LRM ammo, but gets too only even only using missiles. If you want more ammo, replace the RAC2 with AC5, LB5x or (u)AC2, but you'll lose a lot of firepower and the impact of a RAC... And it's always fun see a light rushing towards me expecting a full larmer, and ML+RAC starts pounding... Of course ammo placement is for clarity, near its weapon. Adjust properly.
