As far as I can determine, Cascade Cartridge Company NEVER used CCC as a headstamp.
IIRC, they used Cascade Cart. Co.
Also, I don't know of any manufacturer using CCC in the 1960s.
I would bet that it is marked CCC .45ACP and has an early 1980s year code on it.
That would be Connecticut Cartridge Company. Supposedly it was MADE by CCC to US military specifications (hence the headstamp and the primer crimp), but it wasn't, and it apparently had only the most tangential association with CCC.
It was apparently made in Taiwan, the brass is crap, and the primers are both corrosive AND mercuric.
General rule of thumb is if you run across these stuff you shoot it, scrap the brass, and clean your gun with lots of hot, boiling water.
Or, you just scrap the loaded rounds as being too much of a pain in the ass to deal with.
