No, It's not advisable to strip copper pyro for it's content and pyro is priced accordingly to accommodate the mineral contained within that protects the inner core from being damaged by fire or water.
Pyro is extremely rigid and difficult to strip unless it is done in an industrial stripping machine such as a cable granulator. Even then, will it have to be passed along a conveyor system where the mineral/dust can be blown off and separated properly.
The mineral/dust when inhaled can be quite toxic to the human body too. Leave the stripping of  clean & PVC Pyro to the metal recycling professionals.
