Countering the Heller dissent

where assault rifle ammo needs be kept in an armory now?

Only goverment issue ammo. That has nothing to do with privately purchased ammo in the same caliber.

and ccw is disallowed for 'self defense'?

Conditions for getting a Carrying Permit[edit]
There are three conditions:

fulfilling the conditions for buying a permit (see section above)
stating plausibly the need to carry firearms to protect oneself, other people, or real property from a specified danger
passing an examination proving both weapon handling skills and knowledge regarding lawful use of the weapon
The carrying permit remains valid for a term of five years (unless otherwise surrendered or revoked), and applies only to the type of firearm for which the permit was issued. Additional constraints may be invoked to modify any specific permit. Neither hunters nor game wardens require a carrying permit.

Certainly easier than getting one in DC, New Jersey, or NYC. Come to think of it, it is easier than Wyoming pre-1995
