I'm not sure why we didn't get Sub-Capital Gauss or PPCs, so here's my stab at them:
Weapon Type Ht (Aero) Dmg (Aero) Rng (Aero) Ammo Base Date Cost Weight Space
SC Gauss CAP,AE 7 (7) 60 (6-C) * (Long-C) 6 IS 3073 10M/30K 1,500 1-C*
SC PPC CAP,AE 65 (65) 40 (4-C) * (Long-C) NA IS 3073 1M 1,000 1-C*
I aimed to make the SC PPC heavier and hotter than a NL/35, and shorter ranged and less damage than a NL/45. The SC Gauss was harder to dial in, but I think it works with more range but less damage than a Heavy SCC.
