Ok....well luckily the Ingram also has a burst fire mode and is still better than the SCK. Please explain how the SCK is better than the Ingram X since that seems to be the point you're trying to make.
It's better *in some circumstances* because it offers higher accuracy, making it more effective in the hands of a skilled operator. Throw on a GV3, and it actually offers double the non-mounted RC of the Ingram, making it better overall for sustained fire (which matters a hell of a lot more than FA fire, which you would never use for sustained fire).
Full Auto has it's uses, sure, but overall it doesn't make a weapon better - in a sustained firefight, being limited to that or burst fire actually makes a weapon worse than being limited to semi-auto or burst; the SCK in the hands of, say, a Strength 5(7) human can sustain fire for up to 8 initiative passes before any penalty is suffered, while the Ingram can only sustain for 2 initiative passes before penalty in the hands of the same shooter. If said shooter uses the smartgun in wireless mode, has Agility 5(7) and Automatics 6 and is against a target with Reaction+Intuition 8, that means that over 9 passes the SCX delivers 8*(8+2.33) damage against the Ingram's 6*(8+3), or 82.64 vs 66. That's
before bringing Accuracy into play, and it's delivering roughly an extra two boxes of damage per action. Oh, and after those 9 phases, the Ingram is down to 5 bullets in the mag against the SCK's 22.
