The Dual 425mm Autocannon should use medium ammo, have the same range, tracking and sig as the 425mm autocannon, with twice the rate of fire.
The Dual Heavy Beam Laser should use medium crystals, have the same range, tracking and sig as the Heavy Beam Laser, with twice the rate of fire.
The Dual Heavy Pulse Laser should use medium crystals, have the same range, tracking and sig as the Heavy Pulse Laser, with twice the rate of fire.
The Dual 180mm Autocannon should be renamed to the Dual 200m Autocannon, use small ammo, have the same range, tracking and sig as the 200mm Autocannon, with twice the rate of fire.
The Dual 250mm Railgun should use medium ammo, have the same range, tracking and sig as the 250mm Railgun, with twice the rate of fire.
The Dual 150mm Railgun should use small ammo, have the same range, tracking and sig as the 150mm Railgun, with twice the rate of fire.
There used to be blaster and artillery guns named “Dual …” (I think one was named “Quad …” !!) and those names should be brought back and given the same range, tracking and sig as the single smaller gun, with twice the rate of fire. Doesn’t have to be twice the rate, balancing may require it to be higher or lower than that. The point is gunnery ships ought to have the same option as missile ships to fit turrets that can use the smaller ammo and hit smaller targets more easily.
And why not have some gunnery ships with sig radius bonus, like some missile ships have explosion radius bonus? I think this is one of the things that makes missile ships so much more preferred than gunnery ships in roles like mission blitzing.
Anyway, that’s my suggestion.
