I would recommend sticking with 5.56 for the safest results until the manufacture states otherwise.

Yes. 556/350 Legend/300 Blackout are the same bolt. There is not a separate bolt for these calibers.

300 Blackout is 556 brass. It is coverted by reloadedrs. Of course you can buy it also. 556 bcg works with 300 Blackout headstamp.
